Rupture of uterine scar with extrusion of twin fetuses into the urinary bladder--a case report.

An unusual presentation of a ruptured uterus with extrusion of twin fetuses into the urinary bladder is described. A routine pelvic ultrasound to confirm pelvic collection from a suspended criminally induced abortion revealed a rupture of the anterior wall of the uterus with communication to the urinary bladder and this finding was confirmed at laparatomy. While a high index of suspicion is important in the diagnosis of ruptured uterus, a subtle place for pelvic ultrasound in patients with vaginal bleeding, suprapubic pain and haematuria may be of help.
