Neglected Trivial Trauma - A Cause for Pseudo-acute Kidney Injury

Rupture of the urinary bladder and extravasation of urine into the peritoneal cavity leading to urinary ascites is an uncommon event, usually caused by blunt trauma to the abdomen. A high index of suspicion is required for early accurate diagnosis, which avoids unnecessary investigations and interventions. The disappearance of ascites following indwelling Foley's catheterization and high peritoneal fluid urea and creatinine compared to serum values are keys for diagnosis. Sometimes, the diagnosis may be delayed as the features are mistaken for intrinsic renal disease. Here, we report a case of pseudo-acute kidney injury caused by urinary ascites due to intraperitoneal bladder rupture following blunt abdominal trauma in an alcoholic patient.
