压力性尿失禁常发生于分娩过的妇女,也可见于未婚、未育女性。其病理基础是:①尿道膀胱颈部脱垂松弛,尿道缩短,使尿道张力下降:②尿道膀胱后角(PUV)消失而呈180°(正常呈90°～100°),丧失了正常中段尿道所保持的压力。外科手术矫治就是要将脱垂的膀胱颈提举到耻骨联合后的原来位置,并借以延伸尿道和恢复PUV角。目前常用的手术方法有耻骨上膀胱尿道固定术(Marshall-Marchetti-Krantyz手术)和内窥镜下膀胱颈悬吊术(Stamey手术)两种。自1986年7月以来,我们用自制长导针将Stamey手术方法加以改进,为 Stress urinary incontinence often occurs in women who have given birth, can also be found in unmarried, non-pregnant women. The pathological basis is: ① urethral bladder neck prolapse relaxation, urethral shortening, urethral tension decreased: ② urinary bladder anterior horn (PUV) disappeared and showed 180 ° (normal 90 ° ~ 100 °), the loss of the normal middle urethra The pressure to keep. Surgical correction is to lift the prolapsed bladder neck to the pubic symphysis after the original position, and to extend the urethra and restore PUV angle. Currently used surgical methods are suprapubic bladder urethral fixation (Marshall-Marchetti-Krantyz surgery) and endoscopic bladder neck suspension (Stamey surgery) two. Since July 1986, we have modified the Stamey procedure with a self-made long guide for
