Vaginal birth after cesarean section

When facing a case with prior a cesarean section ,is it safer to allow the patient a trial of vaginal delivery or to do a repeat cesarean section? One of the most controversial issues in obstetric practice in 1980s has been the increased incidence of cesarean deliveries. There has been an increase in cesarean section rate over the past 20 years. The rate of cesarean section remained relatively stable at 3-5 %. This started to change in 1960s. In 1965, cesarean section rate was 8.5% of all deliveries then increased dramatically to reach 16.5% in 1980 and 25% in 1988.
