Obstetric hysterectomy in a population of South East England.

The aim of this study was to estimate the incidence and outcome of obstetric hysterectomy. Of 48,865 women who delivered after 24 weeks' gestation in the South East Thames Region between March 1997 and February 1998, 22 women with obstetric hysterectomy were identified, and 15 prospectively followed-up (71% response rate). The incidence of obstetric hysterectomy was 0.45/1,000 deliveries with one maternal death (4.5%). Identified risk factors were delivery by caesarean section (68%), previous caesarean section (33%) and placenta praevia (24%). Mean blood loss and replacement were 5.2 l and 17 units, with a 38% risk of re-operation and 21% risk of urinary tract injury. Follow-up showed poor general health 6-9 months after delivery with 10 women (67%) attending outpatients and four (27%) requiring emergency admission to hospital. This population survey found a low rate of obstetric hysterectomy but severe morbidity. Obstetric hysterectomy is a good candidate for a national morbidity audit.
