Pseudo-Renal Failure; Urinary Ascites and Uremia due to Bladder Rupture / 대한신장학회지

ABSTRACT

The main feature of acute renal failure is a decline in the glomerular filtration rate. However, urine leakage into the peritoneal cavity due to bladder rupture may cause pseudo-renal failure. This is a situation in which renal function is normal, along with the presence of elevated serum creatinine. A 47-year-old woman presented with abdominal distension and pretibial pitting edema on both lower extremities. She had no traumatic history. She did not complain of abdominal pain, and exhibit neither oliguria nor anuria. Her blood urea nitrogen (BUN) and serum creatinine was 105 and 11.2 mg/dL. Ascites showed that urea nitrogen and creatinine were 160 and 29 mg/dL, respectively. We confirmed bladder rupture by an abdominal CT scan and retrograde cystography. She underwent an emergency laparotomy to repair the ruptured bladder. Azotemia was normalized 2 days after the operation. Here we present a rare case of uremia due to bladder rupture.
