Incidence of uterine rupture in a Teaching Hospital, Sudan

Objectives: This study aims to document the experience of uterine rupture a s a serious common complication of pregnancy in some developing countries l ike Sudan. The study is also aimed at reviewing the main contributing facto rs so as to draw broad lines for a strategy of prevention. Methods: A retrospective study carried out at Medani Teaching Hospital, Med ani City, Sudan. Case notes were reviewed for all patients with uterine rup ture from Ist January 1992 through 31st of December 1997. The data was anal yzed and the literature was reviewed to compare the results of similar stud ies. Results: Out of the total number of deliveries in that period (n=21190), 86 cases were diagnosed to have uterine rupture giving an incidence of 1:246. The main contributing factor to uterine rupture identified in this study, was poor ante-natal care (64%). One most important direct cause of uterine rupture was previous cesarean section scar with or without cephalopelvic di sproportion (n=39) (45%). Seventy-six cases, had complete rupture of uterus . Subtotal hysterectomy was carried out on 69 cases (80%) and 15 cases (17% ) had uterine repair with bilateral tubal ligation. Three patients develope d vesico vaginal fistula (3.5%). The ureter was iatrogenically severed in 2 cases (2%). There were 6 (7%) maternal deaths and 68 (79%) perinatal death s. Conclusion: This study confirms the existence of a serious preventable obst etrical problem. Poor antenatal care, poor provision of health service and low socioeconomic standards, are the main factors contributing to uterine r upture. Those findings would suggest that both social and medical improveme nts will significantly improve survival in mothers with ruptured uterus and reduce the perinatal loss.
