Acute urinary bladder tamponade with hypovolemic shock due to placenta percreta with bladder invasion. Case report.

A rare case with residual tissue of placenta previa invading posterior parts of the bladder as placenta percreta complicated by massive late hematuria with hypovolemic shock two months after gynecologic-obstetric operation is presented. The patient was finally treated by emergency bladder resection. If a grand multipara with a history of hysterotomies, such as cesarean sections, presents lower abdominal pain involving hematuria during pregnancy, placental invasion of the bladder may be suspected. The primary treatment by hysterectomy should be complemented by bladder resection. This placental type may have high steroidogenesis.
