We have taken into consideration the obstetric outcome in 173 women, with prior cesarean section, who were delivered in our hospital between june 1988 and january 1991. This group of patients represented 5.3% of our obstetric population. Overall 64 patients (37%) achieved vaginal delivery and 109 (63%) underwent an iterative cesarean section. Considering the 76 patients (44%) admitted to trial of labour, 64 (84.2%) achieved vaginal delivery and 12 (15.8%) were delivered with iterative cesarean section. No maternal or neonatal complications occurred, even though the silent dehiscence of the uterine scar, found during cesarean section, seems to occur four times (12%) more frequently than that reported in recent literature. It follows that vaginal delivery after prior cesarean section is, in our experience, lacking in risks, and we think that such management may be widely adopted. In 1986 iterative cesarean section represented 35% of cesarean section indications, in 1990 this rate was reduced to 23.7% by the introduction of a policy to allow women to undergo trial of labour.
