Methods: Eighty-nine pregnant women who underwent CD between 37 and 41 weeks of gestation from 2013 to 2015 were enrolled in this study and divided into two groups. Group A consisted of women with previous CD, and Group B consisted of women with previous vaginal deliveries. We performed an ultrasound evaluation of the myometrial and full thickness of LUS (mLUS and fLUS) transvaginally before a CD and evaluated the appearance of LUS during surgery, which was defined as follows: grade I, well-developed;grade II, thin without visible content;grade III, translucent with visible content;and grade IV, either dehiscence or rupture. Results: The median mLUS and fLUS were 1.50 and 4.07 mm in the group A, and 2.75 and 5.37 mm in the group B. We observed significant differences in the median mLUS and fLUS between grades I/II (2.07 and 4.37 mm) and grades III/IV (0.67 and 2.52 mm). Both mLUS and fLUS were predictive factors for grades III/IV and cutoff values were 0.97 mm of mLUS and 3.13 mm of fLUS, having a sensitivity of 87.5% and 75.0%, and a specificity of 87.7% and 91.4% in mLUS and fLUS measurement, respectively. Conclusion: Sonographic measurements of LUS at term may be a feasible and reliable method to predict uterine rupture or uterine dehiscence in women with prior CD.展开更多

Guidelines for Vaginal birth after cesarean (VBAC) indicate that TOLAC offers women with no contraindications and one previous transverse low-segment cesarean. The objective of the current study was to study the outcome of trial of labour after caesarean section (TOLAC), the indications for emergency repeat cesarean section and to determine the maternal and fetal prognosis in vaginal birth after caesarian section (VBAC) at Tshikaji Mission Hospital. Patients, Material and Methods: This is a retrospective study of the records of 126 women were selected to undergo the TOLAC in the department of gynecology and obstetrics at the Tshikaji Mission Hospital over the period from January 1<sup>st</sup> to December 31<sup>st</sup>, 2021. The data on demography, antenatal care, labour and delivery and outcomes were collected from the maternity unit of this hospital. The data were analyzed using SPSS version 2.0. Results: The TOLAC in 126 studied women. The course of work allowed vaginal delivery 107 parturient women, a success rate of successful VBAC of 85% after the TOLAC. The repeat emergency cesarean section was necessary for delivery in 15% of cases for failed TOLAC. There was no maternal mortality, but we recorded one fetal death or 0.8% of perinatal mortality, 2 cases of cicatricial dehiscence, the incidence of 1.6%. Maternal morbidity after delivery on cicatricial uterus was dominated by postpartum hemorrhages, with 19 cases or 15.1% of cases. Cervical dilatation of more than 3 cm at the time of admission, the parity more than 3 and were the significant factors in favor of a successful VBAC. Birth weight of more than 3500 g, fetal distress and malpresentation were associated with a lower success rate of VBAC. The TOLAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas. Conclusion: Pregnancy on a cicatricial uterus represents a high-risk pregnancy. Trial of VBAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas. There is a significantly high vaginal birth after caesarian section (VBAC) success rate among selected women undergoing trial of scar in Tshikaji Hospital. TOLAC remains the option for childbirth in low resource settings as Kasai region in DRC. Adequate patient education and counselling in addition to appropriate patient selection for TOLAC remain the cornerstone to achieving high VBAC success rate.展开更多

Patients and Methods: The current study was randomized controlled trial conducted in Women Health Hospital, Assiut University, Egypt between March 2017 and May 2018 (ClinicalTrial.gov NCT03016273). Patients were divided into: Non bladder flap group: Uterine incision made 1 cm above the vesico-uterine reflection without incision and dissection of the bladder peritoneum and bladder flap group: Standard cesarean section technique with incision and dissection of a bladder flap prior to uterine incision. Results: The study included 150 patients (75 in each arm). The most common indication for CS in both groups was repeated CS. Non-bladder flap group, compared with flap group, showed shorter skin-incision to delivery time and total operative time, and significantly lower mean estimated blood loss and postoperative pain score. Non-bladder flap group, compared with flap group, was more likely to show postoperative microhematuria. The two groups required approximately the same time for post-operative defecation. Conclusion: Omission of bladder flap formation during CS is associated with shorter operative time, less blood loss, less postoperative pain and lower incidence of postoperative hematuria.展开更多
