The present investigation was designed to further our understanding of the interaction of pituitary (luteinizing hormone, LH) and placental (chorionic gonadotropin, CG) gonadotropins with the primate corpus luteum. Studies were performed (1) to characterize the LH/CG receptor population in the

RATIONALE OF THE STUDY. To carry out a retrospective chart review of all patients who had a peripartum hysterectomy in hospitals at different levels of health care in the Pietermaritzburg Hospital Complex to examine the incidence and indications for peripartum hysterectomy. METHODS. The charts of 120 cases of peripartum hysterectomy operations performed between January 2003 and January 2008 in the Pietermaritzburg hospital complex of University of KZN were analysed retrospectively. The total number of deliveries were 48 964. The traditional indications, risk factors and associated complications were revisited to determine if there have been changes in current obstetric practice. RESULTS. The overall incidence of peripartum hysterectomy at the Pietermaritzburg complex of hospital was 0.25/1000 deliveries (95% C1 0.2 – 2.9). Uterine atony, bleeding abruption placentae, placentae praevia, uterine rupture following induction and extension of uterine incision into the uterine arteries comprised 87.9% of the indications for peripartum hysterectomy. By far, the most common complications were wound infection and haemorrhage due to difficult haemostasis. Both comprised 61% of complications, others were bladder injury and renal failure. Coagulopathy occurred in 16.7% of cases of whom 2 died due to massive uncontrollable haemorrhage and 26.7% cases had relaparatomy. There were 13.3% of haemorrhagic shock and 5% developed septic shock. All the patients had blood transfusion, 13.3% of patients received platelets in addition to blood. The results showed that 55.8% had previous caesarean sections while 12.5% had VBAC. There were 75.8% live babies. CONCLUSION. The review noted that there has not been a significant change in the incidence and indications for peripartum hysterectomy. The incidence of peripartum hysterectomy in the study 0.25/1000 compared favourably with the findings from similar studies in different parts of the world. Worldwide the incidence of PH ranges from 0.2 to 5.09/1000 deliveries, in our study the incidence was 0.25/1000. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2012.
