[Usefulness of Ascitic Fluid Analysis for Diagnosis of Intraperitoneal Bladder Rupture : A Case Report].

An inebriated 58-year-old woman with a history of hysterectomy presented to the emergency department with abdominal pain. The patient received hydration and acetaminophen, which led to symptom resolution. The patient returned with severe abdominal pain, 12 hours later. Computed tomography (CT) revealed a large volume of ascites and bladder wall disruption. Ascitic fluid analysis showed an elevated creatinine (Cre) level of 7.56 mg/dl, and the ascites to serum Cre ratio was 2.96, which indicated urinary ascites secondary to bladder rupture. The patient was diagnosed with intraperitoneal bladder rupture and underwent successful conservative treatment using an indwelling urinary catheter.
