子宫下段剖宫产术问世已近百年,共优点之一为子宫膀胱反折腹膜(简称反折腹膜)缝合后,覆盖了子宫切日,减少了粘连的机会。传统的反折腹膜缝合方法是用1号或4号丝线连续缝合。胎儿娩出后子宫收缩,致使子宫侧的反折腹膜缩短,膀胱侧者较长,连续缝合时,如不拉紧缝线,较长的膀胱缘松弛外翻,粗糙面外露。如拉紧缝线,则膀胱缘形成许多皱褶。如缝合技术不佳,将反折腹膜缝得过高或将皱褶集中打在一侧,则可造成膀胱移位。
The lower uterine segment of the caesarean section came out nearly a hundred years, one of the advantages of uterine bladder peritoneal buckling (referred to as the inverted peritoneum) suture, covering the uterine incision, reducing the chance of adhesion. Traditional reverse peritoneal suture method is to use No. 1 or No. 4 suture continuous suture. Uterine contractions after delivery of the fetus, resulting in the contralateral peritoneal shortening of the uterus, the bladder side of the longer, continuous suture, if not tighten the suture, the longer the bladder margin relaxation valgus, rough surface exposed. If tighten the suture, then the bladder margin formed a lot of folds. Such as poor suturing technique, the retroperitoneal sewn too high or will be concentrated in one side of the folds, can cause bladder displacement.
