Late second stage rupture of the uterus and bladder with vaginal birth after cesarean section: a case report and review of the literature.
Rupture of a uterine scar during labor with concomitant severe injury to the maternal bladder has been reported sporadically. Previously reported cases have been diagnosed under a variety of conditions, commonly at the time of repeat Cesarean delivery. A case of maternal bladder rupture diagnosed following forceps-assisted vaginal delivery after Cesarean is presented. Severe bradycardia developed suddenly in the second stage of labor. Rupture of the uterine scar was diagnosed after sudden onset of severe lower abdominal pain with delivery of the placenta. At laparotomy, extensive injury to the bladder was found and successful repair of both injuries was performed. A review of previously reported similar cases with their mechanism of injury and presentation is presented. Serious maternal bladder injury at the time of uterine rupture remains a risk of attempted vaginal delivery after prior Cesarean section.

A pregnancy complicated by mature abdominal burn scarring and its surgical solution: a case report.
Complications of pregnancy secondary to old abdominal burn scars are uncommon but have been reported. Common problems include failure of the scar to stretch (resulting in uterine displacement), maternal discomfort, and occasionally scar breakdown. We report the case of a 23-year-old patient who had a tight circumferential scar involving the majority of the abdomen. The uninvolved skin of the lower abdomen stretched remarkably, but the uterus was displaced inferiorly and anteriorly by the scar. The pregnancy progressed to term under careful supervision. After delivery, a flap created by the naturally expanded skin of the lower abdomen was used to replace a portion of the abdominal burn scar to prevent similar problems in future pregnancies. We know of no other reported case where the naturally expanded skin of pregnancy was used to reconstruct a mature burn scar.
