Aims : We aimed at studying the clinical aspects and the maternal and perinatal prognostics during trial of labor at the Gynecology and Obstetrics Unit. Patients and Methods : This is a transversal and Descriptive study over a period of 06 months from 1 st May to 30 th October 2016 in the Gynecology and Obstetrics Unit of the SourôSanou University Hospital (CHUSS). The data were collected and analyzed by the software Epi info version 3.4.5. Results : During the period of study, 109 cases of trial of labor for a total of 2124 births were registered, with an overall frequency of 5.13%. The average age of the patients was 26.6 years. In 42.2% of cases, the patients were primiparious . Admission was direct in 85.5% of cases. The coverage rate for prenatal consultation was 100%. There was vaginal delivery for 108 patients, ie a success rate of 99.08% for trial of labor. An episiotomy was performed in 18.34% of those who delivered vaginally with a labor time less than 3 hours in 65.13% of cases. The indication of the cesarean section during the failure of the trial of labor was dominated by acute fetal distress in 0.91% of cases. Among the 14 patients who had complications during the postpartum period, 06 cases of postpartum hemorrhage of 22.85%, were noted, but did not occasion any maternal death. We registered 109 newborns including 106 alive (97.2%), 10 fresh stillborn, 02 perinatal deaths and 01 macerated stillborn. Among the 13 cases of perinatal morbidity, infections, neonatal suffering and hypotrophy were largely dominant with 5.5%, 38, and 5.34% of the cases. Conclusion : The results of our study (99.08% of success) argue in favor of vaginal delivery after uterine scar, with little risk related to this scar when the pregnancies are followed closely. Indeed, with a normal and careful obstetric monitoring, a scarred uterus after one segmental cesarean section must be considered as a normal uterus that can allow the woman to deliver simply without her being exposed to any particular risk of uterine rupture.
