Acute obstructive nephropathy

Abstract

Anuria and oliguria are terms used to indicate the varying Suffix of decreased urine output that may be secondary to pre-renal, renal, or post-renal causes. In all cases, it is essential to rule out urethral and/or ureteral obstruction as post-renal causes of this decrease in urine output. Acute obstructive uropathy is of interest to clinicians because it is a common entity that is treatable and often reversible [1, 2]. Patients with acute obstructive uropathy may present with a diversity of clinical findings, but very often they exhibit symptoms and signs of acute renal failure [1, 2]. The diagnosis of obstructive uropathy should be considered in several clinical settings, but particularly in patients presenting with acute renal failure. In most instances, the renal failure due to acute obstructive uropathy is reversible and surgical procedures or instrumentation may completely reverse the clinical picture.
