Hysterectomy on pregnant uterus is a mutilating procedure used by obstetrician only when he haven't choice in case of major complications of pregnancy or delivery. This retrospective study worked on 35 cases of obstetrical hysterectomy performed on 22 months period (January 94-October 95). The frequency of the procedure among all the in hospital deliveries was 0.45%. The mean age of the patients was 31 years, and the mean parity was 7. 77.5% of the women were referred from over surrounding hospitals where natural deliveries had failed. We performed the hysterectomy because of uncontrolled haemorrhage in 71.7%, and infection in 25.8%. Sub-total hysterectomy was performed in 82.8%. Maternal mortality was 20%. Hysterectomy is very mutilating, but is a life rescueing procedure behind a lifethreatening complication of pregnancy or delivery. The best strategy to prevent the necessity of hysterectomy, is to develop the early obstetrical reference program that unfortunately is not yet in practice in our health care system.
