    Study Notes

    Urinary System Notes

    • Kidney Infections: Ascending bacterial infections, often E. coli in women, can cause painful, enlarged kidneys and symptoms of a urinary tract infection (UTI). Prompt treatment with broad-spectrum antibiotics is needed. Massage treatment may be postponed until infection is resolved. Symptoms include fever, flank or mid-low back pain, nausea/vomiting, urgency, frequency, and possible ureter spasm causing renal colic. Diagnosis involves urinalysis, blood tests, and imaging (MRI, CT, Ultrasound). Complications include pus accumulation, pyonephrosis, sepsis, and kidney failure.

    • Kidney Stones: Increasing fluid intake may aid stone passage. Alpha-adrenergic blockers (Tamsulosin) can be used, alongside analgesics. Stones may pass without intervention. Stones are typically composed of calcium oxalate (80%), uric acid, struvite, or cystine. Formation may be prevented with dietary changes, particularly for diets high in protein, vitamin C, and calcium. Genetics, hyperparathyroidism, and gout can be factors. Symptoms include hematuria, frequency, urgency, dysuria, and urinary retention, along with nausea, vomiting, sweating, chills, fever, and lower abdominal pain. Diagnosis involves urinalysis and imaging (US, CT). Treatment includes increasing fluids for smaller stones, alpha-adrenergic blockers, analgesics, and potentially shockwave lithotripsy or endoscopic techniques for larger stones. Prevention involves increased fluid intake, and possible dietary adjustments based on stone composition (calcium, uric acid, oxalate).

    • Glomerulonephritis: Inflammation of the glomerulus can result from past strep infections, hypersensitivity reactions (type II), bacterial infections, hypertension, or lupus. Symptoms include edema, visual disturbances, seizures, and hypertension. It's often associated with proteinuria and hematuria. Prolonged infection and/or hereditary factors can contribute. Acute and chronic forms exist, with acute typically presenting with nephritic syndrome. Chronic more commonly causes nephrotic syndrome.

    • Nephrotic Syndrome: Characterized by insidious onset, normal blood pressure, proteinuria, and hypoalbuminemia. Features include hyperlipidemia and edema. It can result from scarring of the glomerulus.

    • Acute Glomerulonephritis: Abrupt onset, increased blood pressure, significant proteinuria, and hematuria (including RBC casts). Serum albumin levels are low.

    • Chronic Kidney Disease: Progressive damage can lead to kidney failure and/or dialysis. Conditions like polycystic kidney disease can cause fluid-filled cysts. Symptoms in polycystic kidney disease can range from no symptoms to flank pain, frequent infections, and kidney stones. Diagnosis involves blood work (BUN, Creatinine, GFR), and imaging (US, CT). Treatment involves treating sequelae, such as UTIs, hypertension, and kidney stones. Dialysis or transplantation may be necessary for kidney failure. Systemic circulatory massage is inappropriate for edema-related kidney conditions. Minimal abdominal and CVA pressure may be used, while avoidance of low back massage is advised. Lymphatic drainage has limited evidence for benefit.

    • Urinary Tract Infections (UTIs): Infections spread along the urinary tract by bacteria, viruses (like HSV-2), fungi (like Candida albicans), or parasites. Symptoms include frequent, painful urination with urgency, painful ejaculation, and discharge. Risk factors include diabetes, immunocompromised states, obstruction, abnormal bladder function, neurologic diseases, and prostate enlargement. Treatment includes antibiotics. Tight, non-breathable underwear should be avoided. Ascending infection is the most common route. Increased fluid intake helps to flush out bacteria, and hygiene practices like wiping front-to-back can reduce the risk of acquiring infections.

    • Urethritis: Inflammation of the urethra, often caused by sexually transmitted infections (STIs) like chlamydia or gonorrhea. Symptoms include pain during urination, discharge, and difficulty emptying the bladder.

    • Cystitis: Inflammation in the bladder, often accompanied by LUTS.

    • Urinary System Cancers: Renal cell carcinoma (RCC) is the most common type of malignancy affecting the renal pelvis and ureters. Symptoms include abdominal pain, blood in the urine (microscopic or visible), and flank pain. Staging and treatment (surgery, radiation, chemotherapy) depend on the extent of the cancer. Recurrence is possible. Transitional cell carcinoma is a second, less common type.

    • Diagnosis and Treatment: Diagnosis relies primarily on urine samples for UTIs, and urinalysis for other problems, with possible imaging (US, CT) for stones. Medication, surgery, and other treatments are dependent on the particular issue.

    Note on Terminology and Conditions

    • LUTS (Lower Urinary Tract Symptoms): Various symptoms associated with bladder/urethra issues. Includes frequent, painful urination, urgency, and incomplete emptying sensations.
    • RBC casts: Red blood cell casts in the urine potentially indicative of kidney inflammation.
    • Proteinuria: Presence of protein in urine, often indicative of kidney damage.
    • Hematuria: Blood in the urine, another potential indicator of kidney problems or other issues.
    • Hypoalbuminemia: Low levels of albumin in blood.
    • Hyperlipidemia: Elevated blood fat (lipid) levels.
    • Polyuria: Excessive urination.
    • Renal Colic: Severe pain associated with kidney stones.
    • STI: Sexually transmitted infection.
    • NGU: Non-gonococcal urethritis.
    • HSV-2: Herpes simplex virus type 2.
    • CVA: Costovertebral angle (area where kidneys are located).
    • BUN: Blood Urea Nitrogen
    • Creatinine: Blood creatinine
    • GFR: Glomerular Filtration Rate
