Abstract:ObjectiveTo investigate the safety and feasibility of cystoscopy in cesarean section that delayed dehiscence or postpartum hemorrhage.MethodsRetrospective analysis of 60 patients which sutued cervix becaused of delayed dehiscence or rich bleeding in cesarean section from January 2014 to December 2016 in Ruijin Maternal and Child Health Care Hospital.Patients who underwent intraoperative cystoscopy combined with ureter catheterization were considered as research group.Patients who just underwent routine detection of ureter anatomical location were considered as control group.And the operation time,bleeding volume,suture of ureter,cond operation,postoperative infection and complications were analyzed and compared between the two groups.ResultsCompared with the control group,operation time was significantly shortened in the research group[(50±10)min vs.(60±10)min](P=0.0003)and intraoperative bleeding was significantly less[(300±20)ml vs.(350±30)ml](P=0.0000).Postoperative suture and second operation were significantly happened less in research group(P=0.0166,P=0.0303),The postoperative complications were compared with the control group,and the difference was not statistically significant(P>0.05).ConclusionCombination intraoperative cystoscopy withureter catheterization may reduce shorten the operation time and reduce the risk of ureteral ligation and second operation in the cesarean section that requiring suture near the cervix.
