Nontraumatic urinary bladder rupture presenting as renal pseudo-failure and ascites.

A 24-year-old man, with past medical history significant only for nocturnal enuresis until the age of 12 years, presented to the emergency department with acute abdominal pain after an episode of difficulty with micturition in the middle of the night. On presentation, physical examination was suggestive of ascites and laboratories revealed an elevated serum creatinine of 1.88 mg/dL. He was subsequently found to have a ruptured bladder, without any inciting trauma, which required surgical repair. His only surgical history is an unknown, apparently urologic, surgery when he was 11-12 years old. The patient's unique presentation prompts discussion of bladder rupture and its manifestations, the role of clinical information in informing imaging protocol, and the importance of sagittal images in identifying pathology.
