Man With Abdominal Pain

Abstract

A 72-year-old man presented to the emergency department with urinary retention and increasing abdominal pain hours after undergoing transurethral resection of a bladder tumor. His initial blood pressure was 146/104 mmHg, and his pulse rate was 97 beats/min. He had abdominal distension and diffuse tenderness. His potassium level was 6.1 mEq/L, and his serum creatinine level was 2.78 mg/dL, indicating an acute kidney injury. The emergency physician performed a point-of-care ultrasound (Figures 1 and 2), demonstrating free fluid at the liver tip, and confirmed the diagnosis with computed tomography imaging.
