Chapter 50: Renal & Urologic Problems

Advanced renal pathology includes glomerulonephritis involving immunologic glomerular damage and nephrotic syndrome characterized by massive proteinuria, hypoalbuminemia, and generalized edema, necessitating careful fluid management, blood pressure control, and monitoring for complications including infection and thromboembolism. Vascular disorders such as nephrosclerosis and renal artery stenosis are examined for their potential to cause renal insufficiency, requiring antihypertensive management and possible revascularization procedures. The chapter extensively covers nephrolithiasis, explaining crystal formation mechanisms, the classic presentation of renal colic with hematuria, diagnostic imaging approaches, pain management strategies, medical expulsive therapy using alpha-blockers, and interventional procedures including extracorporeal shock wave lithotripsy and ureteroscopy. Functional urologic disorders encompass interstitial cystitis and neurogenic bladder requiring symptom-based management, along with various forms of urinary incontinence (stress, urge, overflow, functional, and mixed types) and urinary retention, often associated with benign prostatic hyperplasia. Urologic malignancies including renal cell carcinoma and bladder cancer are addressed through recognition of hematuria, cystoscopic evaluation, intravesical therapy, surgical interventions ranging from partial nephrectomy to radical procedures, and postoperative care including management of urinary diversions such as ileal conduits. Throughout all conditions, nursing management emphasizes health promotion, early symptom recognition, patient education regarding medication adherence and lifestyle modifications, meticulous monitoring of renal function, prevention of complications, and comprehensive support for patients requiring reconstructive procedures or permanent urinary diversions.
