Rupture uterus: changing trends in etiology and management

Sixty-four cases of rupture uterus which occurred during the period 1980-89 were studied and compared with 70 cases in the preceding decade (1970-79). The changing trends in etiological factors and management of this condition have been demonstrated. While spontaneous rupture continued to account for about two-thirds of the cases (70.3%), the incidence of traumatic rupture uterus has become less than half, from 17.1 to 7.8%, and that of scar rupture has increased to more than double (from 11.4 to 23.4%). As regards management, there are improved results seen with conservative repair of the uterus. It was also seen that a subtotal hysterectomy was more commonly resorted to than total hysterectomy in the later decade. There was a decrease in the overall morbidity from 42.8 to 35.9% and also in the mortality rate from 24.3 to 18.7%.
