    Study Notes

    Renal System Function

    • Maintains fluid and electrolyte homeostasis
    • Excretes urine
    • Acts as a buffering system to control pH
    • Critical for the production of: • Vitamin D to maintain blood calcium balance • Erythropoietin to stimulate red blood cell production • Renin to regulate blood pressure • Growth hormone activation • Prostaglandins secretion

    Fun Facts

    • Kidneys filter 1.2 liters of blood per minute, creating 180 liters of filtrate per day
    • Each kidney has approximately 800,000 - 1 million nephrons
    • 99% of the filtrate is reabsorbed back into the venous system
    • Only 1000-2000 ml of urine is produced per day under normal conditions
    • Urine pH is 4.5
    • The bladder holds 400-500 ml and loses its natural shape and elasticity when overstretched
    • The body senses the urge to void when the bladder contains approximately 200 ml of urine
    • Micturition occurs approximately 8 times per day

    Renal Terminology

    • Anuria: absence of urine
    • Diuresis: increased urine volume
    • Dysuria: painful urination
    • Enuresis: involuntary nocturnal urination
    • Frequency: voiding more frequently than usual
    • Nephritis: inflammation of the kidney
    • Hematuria: blood in the urine
    • Hesitancy: difficulty initiating urination
    • Incontinence: inability to control urination or defecation
    • Lithiasis: presence or formation of stones
    • Nocturia: excessive urination at night
    • Oliguria: decreased urine formation or passing
    • Polyuria: abnormally large urine production
    • Proteinuria: abnormal protein in the urine
    • Pyuria: abnormal white blood cells in the urine
    • Urinary retention: inability to empty the bladder
    • Urgency: intense desire to urinate immediately

    Factors Promoting Proper Renal and Urinary Function

    • Adequate blood flow to and from the kidney
    • Good blood pressure and sufficient fluid intake
    • Functioning filtering system (nephrons, afferent and efferent arterioles)
    • Patent ducts from kidney (ureter) and bladder
    • Intact bladder (no holes, tears)
    • Proper nerve innervation and hormone relay
    • Functioning pelvic floor muscles and sphincter function
    • Proper pH

    Diagnostic Tests

    • Urinalysis and urine culture
    • Renal function tests (SG, osmolality, 24-hr urine, etc.)
    • Ultrasonography
    • CT and MRI
    • Intravenous urography
    • Retrograde pyelography
    • Cystography
    • Renal angiography
    • Cystoscopy
    • Urodynamic studies
    • Lab tests (Serum Creatinine, Blood Urea Nitrogen, etc.)

    Urinary Incontinence

    • Uncontrolled loss of urine affecting 15-50% of the elderly
    • Causes of Transient Incontinence: delirium, infection, pharmacologic, psychological, excessive urine production, restricted activity, and stool impaction
    • Types of incontinence: • Stress incontinence: loss of urine due to increased pressure on the bladder • Urge incontinence: loss of urine due to uninhibited detrusor contraction • Overflow incontinence: loss of urine due to lack of sensation • Reflex incontinence: loss of urine due to neurological dysfunction • Functional incontinence: loss of urine due to cognitive impairment • Iatrogenic incontinence: loss of urine due to medical factors

    Urinary Diversion Devices

    • Urinary catheter: keeping the drainage bag lower than the bladder, choosing the right size, lubricant, and avoiding manipulation
    • Suprapubic catheter: testing client ability to void once obstruction is resolved
    • Nephrostomy tube: tube from kidney to abdomen/flank
    • Ileoconduit: implanting ureter into a 12-cm loop of ileum to abdominal surface with an attached urostomy bag

    Glomerulonephritis

    • Immune-related inflammation of the glomeruli, characterized by proteinuria, hematuria, decreased urine production, and edema
    • Affects both kidneys equally
    • Divided into classifications based on extent of damage, initial cause, and changes

    Acute Renal Failure

    • Complex disorder with many etiological factors and variant clinical manifestations
    • Develops as a consequence of prerenal, intrarenal, or postrenal disorders
    • Rapid accumulation of toxic wastes occurs, leading to azotemia
    • Serum urea (BUN) and creatinine (CR) levels rise
    • Progresses through four phases: initiation, maintenance, diuresis, and recovery
    • Prevention is key

    Surgical Suffixes

    • -ectomy: Excision/removal (e.g., Appendectomy)
    • -oscopy: Looking into (e.g., Gastroscopy)
    • -ostomy: Creation of opening into (e.g., Colostomy)
    • -otomy: Cutting into/incision (e.g., Tracheotomy)
    • -plasty: Repair/reconstruction (e.g., Mammoplasty)

    Types of Surgery

    • Emergency Surgery: Urgent and immediate (e.g., Trauma, Appendectomy)
    • Elective Surgery: Carefully planned and thought out (e.g., Knee replacement)
    • Ambulatory Surgery: Same-day surgery, discharged home same day (e.g., Endoscopy)

    Phases of Surgery

    • Preoperative phase: From decision for surgery to transfer to operating room
    • Intraoperative phase: From transfer to operating room to admission to post-anesthesia care unit (PACU/recovery room)
    • Postoperative phase: From admission to PACU to follow-up evaluation in clinical setting or at home

    Preoperative Care

    • Preoperative preparation: Assessment, laboratory/diagnostics, teaching/education, informed consent, physical preparation, pre-op medications, and pre-op checklist
    • Assessment: Physical (full review of systems) and psychological status
    • Laboratory and diagnostics: Obtaining lab tests, EKG, and CXR based on patient's history to determine surgical and anesthetic risk

    Psychological Condition

    • Explore the meaning of surgery with the patient to understand their perception and anxiety level
    • Encourage clients to express feelings and fears about receiving anesthetic and having surgery
    • Observe client for nonverbal clues indicative of anxiety
    • Reduce client anxiety by explaining the surgical experience

    Intraoperative Care

    • Nursing management: Positioning the patient, proper patient positioning, and anesthesia
    • OR set up: Maintaining a sterile environment, adhering to aseptic technique, and monitoring for breaks in aseptic technique

    Postoperative Care

    • Nursing management: Managing potential complications, such as gastrointestinal, urinary, and alterations in skin/surgical wounds
    • Gastrointestinal: Managing abdominal distension, paralytic ileus, and nausea/vomiting
    • Urinary: Monitoring urinary output, maintaining catheter, and monitoring for UTI symptoms
    • Alterations in skin/surgical wounds: Assessing wound, managing surgical site infections, and monitoring for signs of infection
