Abstract
We describe a patient who presented with acute onset of abdominal pain, oliguria, gross hematuria and uremia. Further examination revealed spontaneous intraperitoneal rupture of the urinary bladder. Upon repair of the rupture, his biochemistry normalized within 24 h. Acute renal failure is characterized by an abrupt decline in glomerular filtration rate (GFR), biochemically reflected by elevation in serum creatinine level. It usually displays multifactorial etiology and can be classified as prerenal, renal and postrenal. In this case report, we describe a situation in which the increase in serum creatinine level was not related to any of these factors and was associated with normal GFR and absorption of urine across the peritoneal membrane following spontaneous rupture of bladder.
