尿道瘘是尿道下裂手术的一种并发症。尿道瘘多发生在中央处,与手术的方法有关。据报道(Horton,1973)尿道瘘的发生率平均在8—20％,由于许多患者有多次手术史,所以修复这些尿瘘是很困难的。采用的几种手术方法有:简单的缝合、Y一V徙前术(Saad等人,1980)、局部皮瓣的旋转(Roberts,1982)和对疑难病例采用带蒂皮管。我们对四例病人采用了菱形皮瓣、二层缝合尿瘘的修复方法。其中每个病人都有多次缝合史。采用局部麻醉,为避免发生远端尿道阻塞,尿道置入一大小适当导尿管。病人恢复满意,术后3—5天拔除导尿管。
Urethral fistula is a complication of hypospadias surgery. Urethral fistula occurred in the central office, and the method of surgery. It has been reported (Horton, 1973) that the average incidence of urethral fistulas is 8-20%. Because many patients have multiple surgical history, it is difficult to repair these urinary fistulas. Several surgical techniques were used: simple suturing, Y-V premolar (Saad et al., 1980), local flap rotation (Roberts, 1982), and pedicled hides for difficult cases. We used a rhombic flap on four patients, and a second floor repair of urinary fistula. Each patient has multiple sutures. Using local anesthesia, to avoid distal urethral obstruction, urethra into a suitable catheter size. Satisfied patients recovered 3-5 days after removal of the catheter.
