A spontaneous intraperitoneal bladder rupture is a rare, serious and life-threatening surgical emergency of various etiologies, with unspecific clinical presentation, and difficult diagnosis. Surgical treatment is the standard therapy for intraperitoneal bladder rupture; however, there is an increasing tendency toward conservative management in selected patients with favorable characteristics. Herein, we report a rare case of a 65-year-old male patient presented to the emergency department with intraperitoneal bladder rupture following an episode of acute urinary retention due to benign prostatic hyperplasia, and which was successfully managed conservatively with urinary bladder catheterization and antibiotic therapy, without any complication.
