Outcome is influenced by a number of factors which are important in patient’s selection. Objectives: The aim of this study was to find out the incidence and feto-maternal outcome of the practice of Trial of labour after Caesarean section. Methodology: This is a retrospective study of cases of vaginal birth after Caesarean section Data were retrieved from the case notes of patients who attempted vaginal birth after Caesarean section from January 1, 2013 to December 31, 2017, a period of five years. Result: There were 10,669 deliveries, 3179 of which were through Caesarean section. This gave a Caesarean section rate of 29.8%. A total of 217 patients attempted vaginal birth after Caesarean section and 83 ended up as repeat Caesarean section (38.2%) while 138 (61.8%) had successful vaginal birth after Caesarean section. Patients with previous vaginal delivery, age range 25 - 29 years and interdelivery interval of greater than or equal to 2 years were more successful at achieving vaginal birth after Caesarean section. The leading indications for the repeat Caesarean section include cephalopelvic disproportion (45.8%), poor progress of labour (19.3%) and hypertensive disorders of pregnancy (8.4%). Conclusion: Vaginal birth after Caesarean section was successful in most of the parturients that attempted it in this study especially in patients within the age range of 25 - 29 years, those that have had previous vaginal delivery and with interdelivery interval of greater than or equal to 2 years.展开更多

Rupture of the uterus is a devastating complication in trial of labour following previous Caesarean section. Evidence suggests that the size of the uterine scar and the residual myometrial thickness (RMT) are associated directly with the risk of uterine rupture and risk of dehiscence in subsequent deliveries. Impact of the prelabour and labour Cesarean section on the RMT has not been studied in detail. Objectives: To compare RMT, Caesarean scar defects and to evaluate the elasticity of the Caesarean scar between women who underwent prelabour and labour Caesarean sections. Methods: This was a Cross sectional analytical study. Women who underwent Caesarean section in their first pregnancy were recruited. Sample was stratified to prelabour and labour Caesarean section groups. Transvaginal ultrasound scan was performed six months following the Caesarean section. Dimensions of the uterus, uterine scar defect, RMT and elastosonography of the uterine scar were assessed. Results: A total of 240 postpartum women were analyzed. Uterine niche was detectable in 194 subjects. Prelabour CS group had demonstrated 91.7% (n = 110) scar defects (uterine niche) out of 120 cases and the rate among labour CS group was 70% (n = 84). There was a significant difference in the presence of uterine niche among 2 groups as Prelabour group was found to have more scar defects (p mm (SD 1.2) and 4.99 mm (SD 1.3) respectively and there was no significant difference (t = 0.38, p = 0.71). There was no significant difference between the dimensions of the uterine CS defects of the studied groups. Prelabour CS group had significantly higher Target strain [0.28 vs. 0.24 (t = 2.12, p = 0.04)] and significantly less strain ratio [1.45 vs. 1.55 (t -2.42, p = 0.04)] than labour CS group indicating a better scar in prelabour group. Conclusion: There was no significant difference in RMT and uterine scar defects between prelabour and labour Caesarean section groups. But prelabour Caesarean section scars were less stiff than labour Caesarean section scars. Further studies are warranted to elaborate on the association.展开更多

The objective is to determine the profile and outcome of patients with one and two previous CSs who performed TOLAC at Panzi General Referral Hospital. Methodology: This is a cross-sectional study with a prospective collection of data of 111 patients with one and two previous CSs at Panzi Hospital from January 2021 to August 2022. Statistical Package for the Social Sciences SPSS version 23 software was used to analyze the collected data. The percentages of categorical variables were summarized in a frequency table. The mean or median with standard deviation was used to summarize quantitative variables. Results: The overall success rate of the TOLAC was 64%, with 63.8% following one previous CS and 64.3% following two CSs. The mean age of the patients was 27.09 years, with an age range of 25 - 34 years. They were mostly pauciparous (52.2%), married (88.3%), with a high school education (60.4%). The inter-delivery interval > 18 months was noted (64.1%) and overweight in 63.9%. More than three antenatal consultations were performed (58.6%). We found a mean gestational age of 38 (34 - 41) weeks. The perinatal mortality rate was 0.9%. However, we did not record any cases of maternal mortality during the study period. Conclusion: TOLAC after one and two previous CS is implemented in the maternity Unit of Panzi Hospital for well-selected patients. In addition, the success rate is similar after TOLAC with an acceptable maternal-neonatal prognosis.展开更多
