Abstract

A 16-year-old boy was admitted for anuria, ascites, and abdominal pain. The patient had undergone a laparoscopic appendectomy two days prior to admission. Initial laboratory analysis revealed a plasma creatinine level of 5,07 mg/dL and blood urea nitrogen level of 75 mg/dL. Computed tomography imaging revealed diffuse abdominal ascites with normal kidneys without signs of hydronephrosis. Laprascopic revision found a 3 mm bladder tear and yielded an aspirate of 1,8 litre abdominal fluid. The abdominal fluid exhibited a fluid : serum creatinine ratio exceeding 1, indicating uroperitoneum. This case underscores the importance of bladder ruptures causing uroperitoneum presenting with azotemia.
