手术方法病人取膀胱截石位,常规消毒铺敷,二把Allis钳夹住阴道残端疤痕,向下,外牵引。于阴道前壁、阴道膀胱间隙注入0.5％奴佛卡因约60毫升,内加0.1％盐酸肾上腺索数滴,(有心血管病者改加催产素),使阴道壁隆起,但前壁正中原手术疤痕处隆起不显。将金属导尿管插入膀胱内,探出膀胱之最低部,于尿道口下2厘米处阴道前壁作∩形切口,深达阴道膀胱间隙,切口下端在二侧侧穹隆处超过膀胱之最下部。钳夹阴道粘膜瓣,向下牵引,同时至上而下作锐性分离阴道粘膜与膀胱,因其间隙已入麻药,层次清楚,分离容易,出血很少。而正中原手术疤痕处因粘连,界线可不清
Surgical approach to take the bladder lithotomy position, conventional disinfection shop, two Allis clamp the vaginal stump scar, down, outside the traction. In the anterior vaginal wall, the vaginal bladder interstitial 0.5% novocaine injection of about 60 ml, plus 0.1% hydrochloric acid adrenal cord a few drops, (patients with cardiovascular disease plus oxytocin), the vaginal wall uplift, but the anterior wall of the Central Plains Surgical scar bulge was not significant. The metal catheter inserted into the bladder, the lowest part of the bladder to explore the urethral orifice 2 cm at the anterior vaginal wall for ∩-shaped incision, deep vaginal bladder gap, lower incision at the side of the dome at the lower part of the bladder at the bottom . Vaginal mucosal flap clamp, down traction, while the top-down for the sharp separation of the vaginal mucosa and bladder, because of the gap has entered the anesthetic, clear level, easy separation, bleeding rarely. The Central Plains surgical scar due to adhesions, the line can be unclear
