Objective: The overall objective of this study was to make a small contribution to improving the health of mothers and children. Method: This is a transversal descriptive study, which took place in the city of Mbuji-Mayi, exactly in the general reference hospitals of this city during the period from March 13 to June 12, 2017, on a sample of 103 cases of cesarean sections. The determinants of the quality of the cesarean section were found by the bivariate analyzes on SPSS. Results: After collecting and analyzing data, we arrived at the results according to which: The cesarean section rate is 8.9%, the fairly good, low and medium quality cesarean section represented 51.5%, 2.9% and 45.6% respectively and if the operating room was available, the probability of having a mid-quality cesarean was 90 times higher (p < 0.001), 14 times higher in the case of a mother and child alive than in the event of death of the child (p < 0.001) and 4.3 times weak or fairly good with an ineffective kit (p < 0.001). Conclusion: The cesarean section rate is 8.9% and the determinants of quality cesarean section were: the availability of the operating room, mother-child prognosis and the availability of the operating kit. These results will help decision-makers in health matters to train and retrain health personnel, particularly midwives, on the benefits of prenatal consultation and its objectives, timely referral, and on the quality of work supervision.
