With the increasing numbers of cesarean sections, there is the need to utilize evidence based techniques to optimize outcomes and minimize complications. We hypothesize that omission of the bladder flap in both primary and repeat cesarean sections will be associated with shorter operating time without a significant increase in intraoperative and postoperative complications. Methods: 550 patients were enrolled in the study. They were randomly allocated in the 2 groups to evaluate the effects of cancelling the bladder dissection. Results: Significant reduction of the total operating time (p = 0.01), skin to delivery time (p = 0.02) and micro-hematuria (p = 0.01) in group with bladder omission. Long term result: Including more bladder adhesion and fibrosis in the cases with bladder dissection. Conclusions: Omission of the bladder dissection achieved short-term advantages as regards reduction of operating time, incision-delivery duration and decreased blood loss as well as long-term effects include different in the bladder adhesion.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
