title: Pseudo-azotaemia due to intraperitoneal urine leakage: a report of two cases.
abstract: Ascites, oliguria and increasing serum creatinine levels are often noted in patients with acute kidney injury. However, these presentations are also observed in patients with intraperitoneal urinary leakage. Bladder perforation without obvious trauma is sometimes mistaken for acute kidney injury. We report two cases of bladder perforation resembling acute kidney injury. The first case was a 37-year-old woman with delayed intraperitoneal urinary leakage following total abdominal hysterectomy, and the second was a 70-year-old woman with spontaneous bladder perforation. Although the initial diagnosis in both cases was acute kidney injury, rupture of the urinary bladder was later identified.
