1990年1月～1997年7月采用各种术式一期矫治尿道下裂患者70例，术后均作尿液引流。按尿液引流方法分为3组：A组，行膀胱造瘘引流35例（50．0％）；B组，行会阴尿道造瘘引流18例（25．7％）；C组，经尿道导管引流17例（24．3％）。A、B、C组患者住院天数分别为40．2、37．4、20．0d；1次手术成功率分别为45．7％、72．2％、82．4％（P＜0．01）。认为熟练的手术技巧配合良好的尿液引流是尿道成形术成功的保障。术后采用尿道导管引流具有尿道支架及引流的双重功能，安全有效，可以满足尿道成形术后短期尿液引流的需要。
January 1990 ~ July 1997 using a variety of surgical treatment of 70 cases of hypospadias in patients with postoperative urinary drainage. According to the method of urine drainage, the patients were divided into three groups: group A, 35 cases (50.0%) were treated by bladder fistula drainage; group B, 18 cases (25.7%) were treated by perineal urethral fistula drainage; Catheter drainage in 17 cases (24.3%). The hospitalization days of patients in groups A, B and C were 40.2, 37.4 and 20.0 days respectively; the success rates of one operation were 45.7%, 72.2% and 82.4% (P <0.01) ). It is considered that successful skill of urethroplasty is considered as a guarantee of skilled surgical technique combined with good urinary drainage. Postoperative urethral catheter drainage has the dual function of urethral stent and drainage, safe and effective, to meet the needs of short-term urinary drainage after urethroplasty.
