    Study Notes

    Urinary Calculi

    • Urinary calculi (kidney stones) are formed by crystals of varying sizes.
    • Calculi can obstruct the urinary tract.
    • Pain associated with renal calculi occurs when the stone irritates the ureter lining.
    • Pain management is crucial for patients with renal calculi.
    • Urinary calculi are a common cause of upper urinary tract obstruction.
    • Lithiasis refers to "stone formation".
    • Nephrolithiasis refers to stones formed in the kidneys.
    • Urolithiasis refers to stones formed elsewhere in the urinary tract (e.g., the bladder).
    • Stones can obstruct the urinary tract at any point.
    • Renal calculi affect approximately 1 in 11 individuals in the United States and other industrialized countries.

    ### Urolithiasis

    • Balance: Kidneys balance water conservation and elimination of insoluble materials such as calcium salts.
    • Factors Influencing Balance: Diet, temperature, and activity affect this balance.
    • Inhibitors: Protective substances like pyrophosphate, citrate, and glycoproteins prevent stone formation.
    • Urolithiasis Formation: Supersaturation, nucleation, and lack of inhibitors contribute to the formation of stones.
    • Supersaturation: High concentration of insoluble salts leads to crystal formation.
    • Nucleation: Crystals can form around an organic matrix or mucoprotein nucleus.
    • Stimulus: Minimal stimulus can initiate crystallization in supersaturated urine (e.g., high salt meal, decreased fluid intake).
    • Urine Acidity/Alkalinity: The pH of urine influences stone formation.
    • Calculus Inhibitors: Presence or absence of calculus inhibitors can influence stone formation.
    • Calcium Calculi: Most common type (75-80%), composed of calcium oxalate and/or calcium phosphate. Associated with high calcium in blood or urine.
    • Uric Acid Calculi: Develop with high uric acid concentration in urine. More common in men, may be linked to gout. Genetic factors play a role.
    • Struvite Calculi: Associated with UTIs caused by urease-producing bacteria (e.g., Proteus). Can grow large, filling the renal pelvis and calyces.
    • Cystine Calculi: Rare, associated with a genetic defect.

    Calcium Phosphate/Oxalate Stones

    • Most prevalent type (75-80% of cases)
    • Associated with high calcium levels (hypercalciuria and hypercalcemia) due to conditions like hyperparathyroidism, immobility, bone disease, and vitamin D intoxication
    • Other risk factors include renal tubular acidosis, prolonged steroid use, alkaline urine, dehydration, and inflammatory bowel disease
    • Management involves pharmacological intervention with thiazide diuretics and potassium citrate
    • Dietary modifications include limiting sodium and animal protein, maintaining calcium intake, and increasing foods that acidify urine
    • Lifestyle adjustments include increasing hydration and engaging in exercise

    Struvite Stones

    • Predominantly caused by urinary tract infections (UTIs), particularly those caused by Proteus bacteria
    • Constitute 15-20% of all kidney stones
    • Management focuses on antibiotic therapy to treat the underlying infection
    • Surgical removal or lithotripsy may be necessary for stone removal

    Uric Acid Stones

    • Associated with gout and high purine intake
    • Characterized by acidic urine
    • Account for 5-10% of all kidney stones
    • Pharmacological management includes potassium citrate and allopurinol
    • Dietary restrictions involve following a low-purine diet
    • Increasing hydration is essential

    Cystine Stones

    • Least common type of kidney stones
    • Result from a genetic defect that increases cystine excretion
    • Acidic urine exacerbates stone formation
    • Treatment involves medications like mercaptopropionyl glycine, potassium citrate, and penicillamine
    • Dietary restrictions include sodium restriction
    • Increasing hydration is crucial for stone management

    Prevalence

    • Prevalence of kidney stones has risen in developed countries, from 5% in 1994 to 9% in 2010 in the U.S.
    • Half of individuals with kidney stones experience a recurrence within 10 years.
    • U.S. incidence varies by region, with the highest frequency in the South.
    • Kidney stones are more common in males than females.
    • Non-Hispanic white populations and those of lower socioeconomic status are at a higher risk.

    Etiology

    • Most kidney stones form in the renal pelvis and are composed of calcium salts.
    • Majority of kidney stones are idiopathic (unknown cause).

    Risk Factors

    • Prior history of kidney stones is the greatest risk factor.
    • Genetic predisposition to mineral accumulation in urine or lack of protective factors may explain familial link.
    • Other risk factors include:
      • Dehydration
      • Obesity
      • Excessive dietary intake of calcium, oxalate, or protein
      • Gout
      • Hyperparathyroidism
      • Urinary stasis or repeated infections
      • Loss of calcium from bones (e.g., due to immobility)
      • Living in a hot climate
      • Certain medications (e.g., probenecid, protease inhibitors, lipase inhibitors, triamterene, chemotherapy, vitamin C, vitamin D, calcium, carbonic anhydrase inhibitors)
      • Sex (Males at higher risk than females)

    Prevention

    • Adequate fluid intake is crucial for preventing all types of kidney stones.
    • Specific measures can be taken to prevent different types of kidney stones:
      • Calcium stones: Reduce sodium and animal protein intake, ensure adequate calcium intake from food, avoid foods high in oxalate (e.g., spinach, nuts, wheat bran).
      • Uric Acid stones: Limit animal protein intake.
      • Medications: Thiazide diuretics (calcium stones), allopurinol (uric acid stones), antibiotics (struvite stones).

    Clinical Manifestations and Therapies

    • Urinary calculi symptoms vary based on size and location
    • Obstructed urine flow causes distention
    • Rough-edged crystalline stones cause tissue trauma
    • Calculi in kidney calyces and pelvis may cause few symptoms
    • Gradual or partial obstruction of urinary flow can cause dull, aching flank pain
    • Renal calculi are often asymptomatic
    • Bladder calculi may cause dull suprapubic pain with exercise or after voiding
    • Renal colic occurs when a stone obstructs the ureter, causing ureteral spasm, stretching, and dilation
    • Renal colic pain radiates to suprapubic region, groin, and external genitals
    • Renal colic pain causes sympathetic response with nausea, vomiting, pallor, and cool, clammy skin
    • UTI manifestations like chills, fever, frequency, urgency, and dysuria can accompany calculi
    • Calculi can cause trauma to the urinary tract resulting in gross or microscopic hematuria
    • Gross hematuria is a common sign of bladder stones

    Urinary Stone Complications

    • Urinary stones can obstruct urine flow at any point in the urinary tract, leading to complications like hydronephrosis and infection.
    • Obstruction can occur from the calyces of the kidney to the distal urethra, hindering urine outflow.
    • Slow-developing obstruction may present with minimal or no symptoms, while sudden obstruction, like a blocked ureter, can cause severe symptoms.
    • Urinary tract obstruction can lead to renal failure.
    • The severity, location, and duration of obstruction determine its impact on renal function.
    • Hydronephrosis is the accumulation of urine in the renal pelvis due to obstructed outflow.
    • Hydroureter is the distention of the ureter with urine.
    • Continued pressure from obstruction can damage the kidney's collecting tubules, proximal tubules, and glomeruli, leading to gradual loss of renal function.

    Acute Hydronephrosis

    • Sudden obstruction leading to acute, colicky flank or back pain
    • May radiate to the groin
    • Hematuria, pyuria, fever, nausea, vomiting, abdominal pain
    • Treatment includes IV therapy, pharmacotherapy for stone composition, lithotripsy or surgery for stone removal
    • Dietary modification, monitoring BUN and creatinine for kidney damage, patient education for recurrence prevention

    Chronic Hydronephrosis

    • Gradual obstruction often asymptomatic until complete obstruction
    • Dull, aching flank pain, hematuria, signs of UTI (pyuria, fever, discomfort), palpable flank mass
    • Treatment includes evaluation of kidney function, IV therapy, lithotripsy or surgery if needed, dietary modification, and patient education for recurrence prevention

    Kidney Stones

    • Often asymptomatic
    • When symptomatic: Dull, aching flank pain, microscopic hematuria, UTI symptoms
    • Treatment includes hydration, pharmacotherapy tailored to stone composition, dietary modification

    Ureteral Stones

    • Renal colic: Acute, severe flank pain on the affected side, may radiate to suprapubic region, groin, or genitals
    • Nausea, vomiting, pallor, cool, clammy skin
    • Treatment includes hydration, dietary modification, analgesics (morphine sulfate, NSAIDs like indomethacin), and pharmacotherapy based on stone composition

    Bladder Stones

    • May be asymptomatic
    • If symptomatic: Dull suprapubic pain, possibly related to exercise or voiding, gross or microscopic hematuria, UTI symptoms
    • If asymptomatic, increased hydration may be the only treatment

    Acute Hydronephrosis

    • Characterized by colicky pain on the affected side.
    • Pain may radiate into the groin.

    Chronic Hydronephrosis

    • Develops slowly.
    • May cause dull, aching back or flank pain.
    • Can cause a palpable mass in the flank region.

    Other Symptoms

    • Hematuria may occur
    • Signs of UTI: pyuria, fever, and discomfort.
    • Gastrointestinal symptoms: nausea, vomiting, and abdominal pain.

    Infection Risk

    • Urinary stasis increases risk of upper and lower UTIs.

    Nonpharmacologic Therapy

    • Small ureteral stones can be treated conservatively as an outpatient.
    • Patients should strain their urine to detect passage of the calculus.
    • Calculus composition should be analyzed.
    • Increased fluid intake reduces the risk of further stone formation and promotes urine output.
    • Recent research does not support fluid intake for promoting stone passage.
    • IV fluids may be needed if patients are dehydrated and cannot consume fluids orally.
    • Kidney stone recurrence is common following the first episode of a symptomatic kidney stone.
    • The highest rate of recurrence occurs during the first year.
    • Dietary changes are recommended based on stone composition to reduce recurrence.
    • See Table 5.6 for specific dietary recommendations.

    Pharmacologic Therapy

    • Acute renal colic is treated with analgesia and hydration.
    • Nonopioid analgesics, such as NSAIDs, are preferred over opioid analgesics.
    • IV NSAID Ketorolac may be administered if oral NSAIDs cannot be administered due to nausea and vomiting.
    • Morphine sulfate, a narcotic analgesic, may be given to relieve pain and reduce ureteral spasm.
    • Indomethacin, an NSAID, may reduce the amount of narcotic analgesia needed for acute renal colic.
    • Anti-emetics can be given for nausea and vomiting.
    • Antibiotics are prescribed for patients with a UTI.
    • Passage of small ureteral stones (5-10mm) may be aided by alpha-adrenergic blockers to relax smooth muscle of the ureters.
    • Thiazide diuretics are often prescribed for calcium calculi to reduce calcium excretion.
    • Potassium citrate alkalinizes urine and prevents stones forming in acidic urine (uric acid, cystine, and some calcium stones).
    • Allopurinol reduces the risk of recurrent calcium oxalate stones when hyperuricosuria and normal urine calcium levels are present.

    Surgical Intervention

    • Surgical removal of calculi is indicated in cases of severe obstruction, recurring infection, intractable pain, or heavy bleeding.
    • Surgery may also be considered for patients who do not pass a stone after 4-6 weeks of outpatient treatment.
    • Lithotripsy, using sound or shock waves to crush a stone, is the preferred treatment.
    • Extracorporeal shock wave lithotripsy (ESWL) is a noninvasive technique.
    • Acoustic shock waves are aimed at the stone under fluoroscopic guidance and shatter the stone.
    • Shock waves travel through soft tissue without damage and pulverize the stone into fragments that can pass through the urinary tract.
    • Lithotripsy can be performed during an office visit or as an outpatient procedure.

    Collaborative Care for Urinary Calculi

    • Focus: Relieving acute symptoms, destroying or removing stones, and preventing further stone formation.
    • Asymptomatic stones: Managed conservatively on an outpatient basis.
    • Urgent Treatment: May be necessary depending on stone location, obstruction, pain, bleeding, kidney function, and UTI presence.

    Diagnostic Tests

    • Urinalysis: Assesses for hematuria, WBCs, and crystal fragments.
      • Urine pH: Helps identify stone type.
        • pH < 5.5: Suggests uric acid calculus.
      • Nitrites, WBCs, and bacteria: May indicate a UTI.
    • 24-Hour Urine Collection: Determines urine volume, pH, and levels of calcium, oxalate, uric acid, citrate, sodium, and potassium to identify causes of lithiasis.
      • Elevated Calcium Levels: May be due to hyperparathyroidism, Cushing syndrome, or osteoporosis.
      • Elevated Uric Acid Levels: May be associated with gout or risk of uric acid calculi formation.
      • Urine Oxalate Excretion: Helps differentiate calcium oxalate from calcium phosphate stones.
    • Stone Analysis: Determines stone type and guides prevention strategies.
    • Serum Electrolyte and Renal Function Tests: Evaluate kidney function and identify factors contributing to calculus formation.
      • Electrolyte Abnormalities: Possible in patients who have been vomiting.
      • Serum Calcium, Phosphorus, and Uric Acid Levels: Can help identify factors contributing to calculus formation.
      • Serum Parathyroid Level: Obtained if hyperparathyroidism is suspected as a cause.
    • Imaging Tests:
      • KUB (Kidneys, Ureters, and Bladder) X-ray: Can identify calculi as opacities.
      • Renal Ultrasonography: Detects stones, evaluates kidneys for hydronephrosis, and is preferred over CT for pregnant women.
      • CT Scan of the Kidney: Identifies stone size and location, ureteral obstruction, hydronephrosis, and other renal disorders.
    • Cystoscopy: Visualizes and potentially removes calculi from the urinary bladder and distal ureters.

    Percutaneous Lithotripsy Techniques

    • Percutaneous ultrasonic lithotripsy utilizes a nephroscope inserted through a flank incision to access the kidney pelvis.
    • An ultrasonic transducer fragments the stone, with fragments removed through the nephroscope.
    • Laser lithotripsy offers an alternative to ultrasonic lithotripsy, using laser beams to disintegrate stones without harming soft tissue.
    • A nephroscope or ureteroscope, guided via cystoscopy, delivers the laser probe to the stone.

    Post-Lithotripsy Procedures

    • A double J stent may be inserted into the ureter after ESWL or other lithotripsy procedures to maintain its patency.

    Surgical Interventions for Calculus Removal

    • Ureterolithotomy involves an incision in the ureter to remove a calculus.
    • Pyelolithotomy entails an incision in the kidney pelvis for stone removal.
    • Nephrolithotomy may be necessary for staghorn calculi invading the calyces and renal parenchyma.

    Bladder Stone Removal

    • Bladder stones can be removed using an instrument passed through a cystoscope to crush the stones.
    • Remaining fragments are irrigated out of the bladder with an acidic solution to counter the alkalinity that contributed to stone formation.

    Urolithiasis in Newborns and Infants

    • Urolithiasis in newborns and infants is less common in the United States but has seen an increase in incidence over the past 10 years.
    • Risk factors for infants include low birth weight, furosemide use, and metabolic disorders.
    • Clinical presentation in infants is nonspecific, but vomiting and restlessness are common.
    • Limited research exists on stone resolution, medical, and surgical interventions in this population.

    Urolithiasis in Children and Adolescents

    • Urolithiasis incidence is increasing in children, but data is limited due to lack of central database and consistent reporting.
    • The most common symptoms are dysuria, hematuria, and sharp pain in the back, lower abdomen, or groin.
    • Pain can be short or long-lasting, accompanied by nausea, vomiting, fever, and chills.
    • Some children pass stones without symptoms, while others require interventions like shock wave lithotripsy, cystoscopy, ureteroscopy, or percutaneous nephrolithotomy.
    • Factors increasing risk include urinary tract defects, metabolic disorders like hypercalciuria, family history, dietary factors, cystic fibrosis, obesity, and repeated UTIs.
    • Follow-up care involves screening for risk factors with a 24-hour urine sample analysis for hypercalciuria, hyperuricosuria, hypomagnesuria, hyperoxaluria, and hypocitraturia to prevent renal insufficiency.

    Urolithiasis in Pregnant Women

    • Symptoms during pregnancy are common and can be misdiagnosed as appendicitis, diverticulitis, or placental abruption.
    • Complications from untreated stones include premature labor, intractable pain, urosepsis, and interruption of normal labor progression.
    • Diagnosis and treatment are complex due to limitations in using radiation, anesthesia, and surgery.
    • Renal ultrasonography is recommended for imaging, and conservative management, ureteroscopy, or nephrostomy are used for larger stones.

    Urolithiasis in Older Adults

    • Common presentations include atypical or absent pain, fever, diarrhea, pyuria, UTIs, and bacteremia.
    • Diagnosis is often delayed with older adults due to atypical presentations and increased incidence of conditions like UTIs and diarrhea.
    • Higher suspicion for urolithiasis is needed for earlier diagnosis and interventions, improving outcomes and prognosis.
    • Uric acid stones and atypical stone compositions are associated with older age.
    • Older individuals are less likely to pass stones spontaneously and more likely to need surgical intervention.

    Nursing Assessment for Urolithiasis

    • Patient Observation: Nurses should observe for signs of pain, including grimacing, moaning, guarding the flank area, bending at the waist, pacing, and seeking various positions.
    • Patient Interview: Obtain dietary history including calcium, sodium, fluid, fruits/vegetables, protein, high-oxalate foods, and purines intake. Review medications for potential stone-forming risks.
    • Pain Assessment: Focus questions on flank, back, or abdominal pain, including location, radiation, characteristics, timing, and aggravating/relieving factors. Inquire about nausea/vomiting, dehydration, prior/family history of kidney stones, and current/past treatments.
    • Physical Examination: Assess general appearance, position, vital signs, skin color, temperature, moisture, and turgor. Note abdominal/flank/costovertebral tenderness. Examine urine for volume, color, and presence of hematuria, bacteria, and pyuria.
    • Kidney Assessment: Palpate and percuss the kidneys carefully, remembering older adults may have difficulty with palpation due to decreased adrenal cortex mass. Avoid blunt percussion in frail older patients. Palpate the costovertebral angles and flanks for pain/tenderness..
    • Flank Color: Carefully correlate flank color and symmetry with other diagnostic findings. The presence of ecchymosis (Grey Turner sign) may indicate trauma, such as blunt wounds, penetrating wounds, or lacerations.

    Urolithiasis Diagnosis Problems

    • Patients with urolithiasis may experience acute pain.
    • Urinary retention is a possible problem for patients with urolithiasis.
    • Lack of knowledge about urolithiasis can be a challenge for patients.
    • Patients may neglect adequate health maintenance.
    • Anxiety is a common problem for patients with urolithiasis.
    • Patients are at risk for infection.

    Urolithiasis Treatment Goals

    • Pain control: Patients should report pain levels of 3 or less on a scale of 0 to 10.
    • Adequate urine output: Maintain a urine output of 2500 mL per 24 hours.
    • Prevention of UTI: Patients should not experience signs and symptoms of urinary tract infection.
    • Recurrence prevention: Patients should verbalize a plan to reduce the risk of future urolithiasis.
    • Anxiety management: Patients should express reduced anxiety about urolithiasis-related pain.

    Urolithiasis Implementation

    • Treatment for urolithiasis typically occurs in an outpatient setting.
    • Hospitalization is needed for patients with acute pain or large stones.
    • Collaboration with healthcare teams is crucial for managing complications such as UTI, obstruction, and hydronephrosis.
    • While pain management is immediate, patient education and health promotion are critical for long-term urinary health.
    • Lifestyle modifications are essential for patients with urolithiasis to reduce the risk of stone recurrence.

    Urolithiasis Pain Management

    • Pain is a primary symptom of urolithiasis, especially when a stone blocks the ureter (ureteral obstruction).
    • Invasive and non-invasive procedures for stone removal (like lithotripsy) can also cause pain.
    • Assess pain using a pain scale, including characteristics of the pain.
    • Administer analgesics as prescribed, monitor their effectiveness using the pain scale, and document the patient's response.
    • NSAIDs can significantly decrease the need for narcotic analgesics for renal colic.
    • Encourage ambulation, unless contraindicated, to help the stone pass through the ureter.
    • Use non-pharmacologic measures, such as positioning, heat, relaxation, and distraction, as adjunctive therapy.
    • Monitor urinary output, catheters, incision, and wound drainage after surgery.
    • Pain after surgery could indicate a blocked catheter, infection, or hematoma at the surgical site.
    • Teach outpatient patients how to manage pain.

    Urolithiasis: Urinary Output Monitoring

    • Urolithiasis can cause urinary tract obstruction, which can lead to hydronephrosis (swelling of the kidneys).
    • Monitor for signs of hydronephrosis, such as dull flank pain and changes in renal function tests.
    • Measure urine output, especially if the patient has a catheter.
    • Strain all urine to collect stones, which can be analyzed to prevent future stones.
    • Document hematuria, dysuria, frequency, urgency, and pyuria. These symptoms can indicate stone passage, complications, or a UTI, which may require antibiotics.

    Urolithiasis Overview

    • A completely blocked ureter can lead to hydronephrosis and kidney damage on the affected side.
    • While one ureter is blocked, the other kidney continues to function, so urine output may not significantly decrease.
    • Early signs of renal failure include an increase in BUN and serum creatinine.
    • Obstruction can cause stasis, infection, or irreversible kidney damage.

    Nursing Care for Urolithiasis

    • Ensure the patency and integrity of catheter systems to maintain free urine flow.
    • A kinked or plugged catheter, particularly a ureteral or nephrostomy tube, can harm the urinary system.
    • Properly label catheters to avoid mistakes like inappropriate irrigation or clamping.
    • Measure urine output and adjust fluid intake to maintain 2-2.5 L of urine per day.

    Patient Teaching

    • Educate patients about urolithiasis, its consequences, diagnostic and therapeutic procedures, and prevention strategies.
    • Instruct patients to collect and strain all urine, saving any stones for analysis, and to report any changes in urine output or characteristics.
    • Emphasize the relationship between renal calculi and UTIs, highlighting preventative measures and the importance of prompt treatment.

    Reducing the Risk of Recurrent Urolithiasis

    • Discuss the importance of adequate fluid intake to reduce the risk of recurrence.
    • Encourage increased fluid intake during warm weather and strenuous activity.
    • Explain the relationship between weight-bearing activity and calcium retention in the bones.
    • Encourage physical activity to prevent bone resorption and potential hypercalciuria.
    • Teach patients with frequent UTIs measures to reduce their incidence and lithiasis risk.

    Evaluation

    • Evaluate patients based on selected outcomes and nursing diagnoses, adjusting the plan of care based on their response to interventions.
    • Assess for potential complications like infection or kidney damage, even if a stone has passed.
    • Expected outcomes include pain relief, absence of UTI signs and symptoms, appropriate dietary choices, and adequate fluid intake.

      • Medications: Probenecid, furosemide, and certain chemotherapy agents
    • Complications
      • Obstruction of urine flow, potentially causing hydronephrosis and renal failure
      • Infections due to urinary stasis
      • Chronic pain and urinary retention
    • Diagnosis
      • Urinalysis: identifies hematuria, pyuria, and crystal fragments
      • 24-hour urine collection: assesses stone composition and risk factors
      • Imaging: Ultrasound, CT Scan, and KUB X-ray to locate stones and assess complications
      • Chemical analysis of passed stones helps prevent recurrence
    • Management
      • Pain management: NSAIDs (first-line), opioids if needed, antiemetics
      • Hydration: maintain a urine output of 2 to 2.5 L/day
      • Lithotripsy: shock waves break stones into smaller fragments
      • Surgery: Ureterolithotomy, pyelolithotomy, or nephrolithotomy for large stones
    • Prevention
      • Increase fluid intake: at least 2.5-3 L/day to reduce recurrence
      • Dietary changes: adjust based on stone type (e.g., lower purines for uric acid stones)
      • Medications: thiazide diuretics for calcium stones, allopurinol for uric acid stones
      • Treat and prevent UTIs to decrease the risk of struvite stones

    Normal Urinary Function

    • The urinary system filters blood, produces urine, and regulates blood pressure
    • It consists of kidneys, ureters, bladder, and urethra

    Kidney Functions

    • Filters blood to remove waste and excess substances
    • Reabsorbs nutrients and water, glucose, and electrolytes
    • Produces erythropoietin for red blood cell production, calcitriol (active vitamin D), and renin for blood pressure regulation

    Normal Urine Composition

    • Clear, pale yellow to amber
    • pH: Slightly acidic (around 6)
    • 95% water
    • Electrolytes like sodium, potassium, and calcium
    • Metabolic waste products urea, creatinine, and uric acid
    • No significant bacteria, white blood cells, blood, or crystals

    Normal Urine Output

    • 1-2 liters per day in adults
    • Output varies based on hydration, diet, and activity

    Prevention of Stone Formation

    • The kidneys balance conserving water with eliminating calcium and oxalate
    • Citrate and glycoproteins in urine prevent crystal formation by binding with minerals
    • Normal urinary function keeps potential stone-forming compounds in solution and removes them regularly

    Dietary Factors

    • High sodium, animal protein and high-oxalate foods (e.g. spinach, nuts) increase risk of urolithiasis.
    • Dehydration or insufficient fluid intake promotes stone formation by concentrating urine.
    • High purine intake is linked to uric acid stones.

    Medical Conditions

    • Hyperparathyroidism increases calcium in urine, increasing urolithiasis risk.
    • Bone disease and vitamin D intoxication elevate calcium levels, increasing risk.
    • Gout is linked to uric acid stones.
    • Obesity and metabolic disorders (e.g. hypercalciuria) increase urolithiasis risk.

    Medication Use

    • Furosemide and certain protease inhibitors increase the risk of urinary stones.
    • Calcium and vitamin D supplements can elevate calcium in the urine.

    Infections

    • Frequent urinary tract infections (UTIs), especially with urease-producing bacteria (e.g. Proteus) are a risk for struvite stones.

    Demographic and Lifestyle Factors

    • People living in hot climates are at an increased risk due to dehydration.
    • Low birth weight in infants and genetic predisposition are risk factors.
    • Physical inactivity potentially increases calcium excretion from bone loss, raising risk.

    Anatomical and Structural Factors

    • Urinary stasis or congenital urinary tract defects promote stone formation.
    • These conditions allow minerals to accumulate rather than being flushed out regularly.

    Pain Behavior

    • Patients with urolithiasis (kidney stones) often display severe pain indicated by grimacing, moaning, and guarding of the flank area.
    • Patients may bend at the waist, pace, or assume unusual positions to relieve pain.
    • Responses to pain vary: some patients are pale and stoic, while others cry out during intense pain episodes.

    Dietary and Medication History

    • Dietary history should include assessment of calcium, sodium, protein, high-oxalate foods (e.g., spinach, nuts), and purines intake.
    • Review medications for those that increase stone risk, such as diuretics and calcium supplements.

    Pain Characteristics

    • Assess pain location (flank, back, or abdomen), radiation, characteristics (e.g., sharp, dull), timing, and factors that aggravate or relieve pain.
    • Also inquire about additional symptoms, such as nausea, vomiting, chills, or fever, and any history of kidney stones.

    General Appearance

    • Assess vital signs (monitor for fever, tachycardia).
    • Observe skin color, temperature, and moisture for signs of distress.
    • Assess turgor to identify possible dehydration.

    Abdominal and Flank Examination

    • Palpate for tenderness in the abdominal, flank, or costovertebral regions.
    • In older adults, palpation may be challenging due to age-related changes (e.g., reduced adrenal mass).

    Urine Assessment

    • Observe urine characteristics such as color, pH, and presence of hematuria, pyuria, or bacteria.
    • Strain urine for any passed stones, saving stones for analysis.

    Kidney Assessment

    • Palpate the costovertebral angles for tenderness (avoiding blunt percussion in frail individuals).
    • If ecchymosis (Grey Turner sign) is present, consider other possible injuries (e.g., trauma).

    Overall Assessment Approach

    • This assessment approach emphasizes the importance of pain characteristics, dietary and medication history, urinary symptoms, and physical signs to indicate the presence and impact of urinary calculi.

    Diagnostic Tests for Urolithiasis

    • Urinalysis is used to detect blood in urine (hematuria), white blood cells, and crystal fragments.
      • pH level indicates the potential stone type:
        • pH < 5.5 suggests uric acid stones
      • Nitrites, WBCs, and bacteria suggest a UTI
    • 24-hour urine collection assesses urine volume, pH, and levels of calcium, oxalate, uric acid, citrate, sodium, and potassium.
      • High calcium may indicate conditions like hyperparathyroidism, Cushing syndrome, or osteoporosis.
      • Elevated uric acid levels are linked to gout or uric acid stones.
      • Urine oxalate excretion helps differentiate calcium oxalate from calcium phosphate stones.
    • Chemical analysis of passed stones determines the stone composition.
      • This helps tailor preventive measures for recurrence.
    • Serum electrolytes and renal function tests evaluate kidney function and contributing factors to stone formation.
      • Electrolyte imbalances (e.g., from vomiting) could indicate dehydration
      • BUN and creatinine levels assess kidney health and risk of renal failure
    • Serum calcium, phosphorus, and uric acid levels identify metabolic issues contributing to stone formation.
      • High calcium or uric acid may indicate conditions like hyperparathyroidism or gout.
    • Serum parathyroid level assesses for hyperparathyroidism as a possible cause.
      • Elevated parathyroid hormone suggests a metabolic contributor to stone formation.

    Imaging Tests

    • KUB (Kidneys, Ureters, and Bladder) X-ray identifies calculi as opacities in the urinary tract.
    • Renal Ultrasonography detects stones and evaluates for hydronephrosis. This is the preferred imaging method for pregnant women due to the absence of radiation.
    • CT Scan of the Kidney locates the size, position, and obstruction caused by stones, hydronephrosis, and other renal disorders.
    • Cystoscopy visualizes and can remove stones from the bladder or distal ureters.
    • These diagnostic tests are essential for identifying stone composition, kidney function, metabolic contributors, and any complications related to urolithiasis. The results guide treatment and prevention strategies specific to the stone type and patient’s health.

    Surgical Interventions

    • Indications for surgery: Severe obstruction, recurrent infections, intractable pain, heavy bleeding, or failure to pass a stone after 4–6 weeks.
    • Types of surgery:
      • Lithotripsy: Uses sound or shock waves to fragment stones.
      • Extracorporeal shock wave lithotripsy (ESWL): Noninvasive method using shock waves outside the body to break down stones.
      • Percutaneous Ultrasonic Lithotripsy: Uses a nephroscope inserted into the kidney pelvis to fragment stones for removal.
      • Laser Lithotripsy: A laser disintegrates the stone without harming soft tissue.
      • Surgical Removal:
        • Ureterolithotomy: Incision in the ureter to remove stones.
        • Pyelolithotomy: Incision in the kidney pelvis for stone removal.
        • Nephrolithotomy: Removal of staghorn calculus extending into the calyces.

    Pharmacologic Interventions

    • Pain Management:
      • NSAIDs (first-line) for acute pain relief in renal colic.
      • IV ketorolac for patients who cannot take oral NSAIDs.
      • Morphine sulfate if NSAIDs do not control pain or if ureteral spasm is present.
      • Indomethacin suppositories may reduce the need for narcotics.
      • Antiemetics for nausea and vomiting associated with pain.
    • Medications to Prevent Stones:
      • Thiazide diuretics: Reduce urinary calcium to prevent calcium stones.
      • Potassium citrate: Alkalinizes urine to prevent stones that form in acidic environments (e.g., uric acid, cystine).
      • Allopurinol: Prevents calcium oxalate stones in patients with hyperuricosuria and normal calcium levels.
      • Antibiotics: Prescribed if a UTI is present to prevent struvite stones.
    • Alpha-Adrenergic Blockers:
      • Alpha-blockers relax ureteral muscles, aiding the passage of smaller stones (5-10 mm).

    Non-Pharmacologic Interventions

    • Hydration: Maintain high fluid intake to achieve urine output of 2–2.5 L/day.
    • Straining Urine: Patient should strain urine to capture stones for analysis.
    • Dietary Modifications: Tailored to the stone type:
      • Limit sodium, oxalate, or purine intake based on stone composition.
      • Increase foods that acidify or alkalinize urine as needed.
    • Physical Activity: Encourage weight-bearing exercises to prevent bone resorption and hypercalciuria.

    Collaborative Care

    • Healthcare Team: Collaborate with urologists, nephrologists, dietitians, and other specialists.
    • Dietitian Consultation: Develop individualized dietary plans based on stone composition.
    • Patient Education: Provide information on hydration, dietary changes, and lifestyle adjustments.
    • Diagnostic Support:
      • Assist with diagnostic testing (e.g., urinalysis, imaging) to monitor progress.
      • Educate on the importance of regular 24-hour urine collections for patients with recurrent stones.
    • Follow-up Care:
      • Regular check-ups to evaluate kidney function, stone recurrence risk, and patient adherence to lifestyle changes.

    Outcome Evaluation for Urolithiasis Interventions

    • Effective Interventions:
      • Pain management successful if pain is at 3 or lower on a 0-10 pain scale, allowing for daily activities
      • Consistent adequate urine output of 2 to 2.5 liters per day, urine appears clear, no hematuria, and appropriate pH for stone prevention
      • No presence of UTI symptoms with lab values within normal limits
      • Adherence to dietary recommendations (dependent on stone type) and consistent maintenance of hydration, with understanding of these adjustments
      • Reduced anxiety regarding urolithiasis and clear understanding of prevention strategies, ability to identify and report potential complications

    Ineffective Interventions:

    • Uncontrolled Pain:

      • Continued or increasing pain above 3 on a 0-10 scale, impacting daily activities
      • Pain-related anxiety and potentially ineffective use of nonpharmacologic pain management techniques

    • Insufficient Urinary Output:

      • Urine output below 2 liters per day, suggesting insufficient hydration
      • Hematuria, cloudiness, or odor in urine may suggest infection or stone movement
      • Rising BUN and creatinine levels may indicate declining kidney function or obstruction

    • Signs of Infection:

      • UTI symptoms (fever, dysuria, pyuria), indicating inadequate infection prevention or need for further intervention
      • Laboratory tests confirm infection requiring immediate treatment and reassessment of prevention measures

    • Non-Adherence to Dietary and Lifestyle Changes:

      • Continued stone recurrence despite recommendations, potentially due to poor adherence
      • Urinalysis or 24-hour urine tests reveal unaddressed stone formation risk factors

    • Persistent Anxiety and Lack of Understanding:

      • Continued anxiety or uncertainty regarding urolithiasis management and incomplete understanding of prevention plan
      • Difficulty recognizing symptoms requiring medical attention, increasing risk of complications

    • The outcome evaluations serve as a gauge for intervention effectiveness and help guide adjustments to improve the patient's condition and prevent complications

    Urolithiasis Management in Unique Populations
