Three-Year Outcome afterUrinary Diversions in Patients with Obstructive Uropathy

Obstructive uropathy accounts for less than 5% of all instances of acute renal failure [1] and the causes are genitourinary tract malignancies, benign prostatic hypertrophy, urolithiasis, or retroperitoneal mass, and it is more common in the elderly [2–4]. The clinical courses progressing to an established renal failure are known to be either rapid or insidious, depending on the duration to the completion of the bilateral urinary tract obstruction. Urinary diversions such as nephrostomy or retrograde ureteral catheterizations are effective and the renal function usually recovers with a marked diuresis [5, 6]. The mortality rate is reported to be 50% at 3 months or 90% at 1 year in cases of malignancy-induced obstructive uropathy [7, 8].
