Fifty cases of uterine rupture were managed in 4 years giving a frequency of 1 per 89.9 deliveries. There was an obvious difference between those with a previously scarred uterus (34) vs those without a scar (16) cephalopelvic disproportion, grand multiparity and mismanagement of cases by traditional birth attendant (TBAs) were the common etiologic factors in the unscarred uterus, cephalopelvic disproportion, forceps delivery, grand multiparity and prolonged first stage of labour were the common etiologic factors in patients with previously scarred uterus. In the unscarred group both maternal and foetal (81.6%) mortality was high (JPMA 43: 174, 1993).
4年间共处理50例子宫破裂病例，发生率为每89.9次分娩中有1例。有子宫瘢痕史者（34例）与无瘢痕者（16例）之间存在明显差异。头盆不称、多产以及传统接生员对病例处理不当是无瘢痕子宫组常见的病因，而头盆不称、产钳助产、多产及第一产程延长是有子宫瘢痕史患者常见的病因。在无瘢痕组，孕产妇及胎儿死亡率均很高（《巴基斯坦医学协会杂志》43: 174, 1993）。
