Spontaneous urinary bladder rupture: a rare differential for lower abdominal pain in a female patient.

We report a rare case of spontaneous "idiopathic" rupture of the urinary bladder in a 38-year-old previously-fit and -well woman, who presented with symptoms of severe lower abdominal pain. Computed tomography of the abdomen and pelvis indicated the preliminary findings, but the final diagnosis was confirmed only at laparoscopy. The bladder was repaired. The postoperative cystogram showed excellent healing of the bladder, with no further intra-abdominal urinary leakage.
