吻合口腹侧成形术修复尿道下裂术后狭窄

目的 探讨吻合口腹侧成形术治疗尿道下裂术后狭窄的效果。方法 2000年8月～2005年12月，对20例尿道下裂术后吻合口狭窄患者以腹侧成形术进行矫冶。年龄2～27岁，中位年龄6，4岁。均表现为尿道下裂矫正术后排尿困难、尿线无力；除3例排尿呈线外，17例排尿呈滴状，其中3例出现急性尿潴留，4例反复出现尿频、尿急、尿痛。16例行尿道逆行造影及排尿性膀胱尿道造影，尿道狭窄段长0．5～1．0cm，平均0．7cm．合并近段尿道不同程度扩张，其中9例形成明显憩室。尿常规检查，16例白细胞＋＋～＋＋＋，13例脓细胞±～＋＋。结果 术后伤口愈合良好，排尿顺畅。获随访2个月～4年，平均2．3年。患者排尿困难均消失，排尿有力，尿线粗细正常，无再次狭窄及尿瘘，阴茎无弯曲，外观满意，尿常规检查恢复正常。结论 吻合口腹侧成形术治疗尿道下裂术后短段吻合口狭窄，操作简便，效果确切。

VENTRAL URETHROPLASTY FOR POSTOPERATIVE URETHRAL STRICTURE IN PATIENTS WITH HYPOSPADIAS

OBJECTIVE: To investigate the effect of ventral urethroplasty for postoperative anastomotic stricture in patients with hypospadias. METHODS: From August 2000 to December 2005, 20 patients with anastomotic stricture after hypospadias repair were treated with ventral urethroplasty. The age ranged from 2 to 27 years with an average of 6.4 years. All patients showed dysuria after operation. Main clinical manifestation included dysuria and acraturesis. Interruption of urinary stream occurred in 17 cases; of them, 3 cases had urinary stasis and 4 cases had frequent micturition, urgent micturition and pain in urination. Urethrography and cystourethrography showed 0. 5-1. 0 cm stricture with proximal dilation of urethra in 16 cases and obvious diverticularization in 9 cases. Urine routine examination showed that white blood cell was ++ to ++++ in 16 cases and pus cell was +/+ to ++ in 13 cases. RESULTS: Twenty cases were followed up 2 months to 4 years (mean 2.3 years). All the cases achieved good results in urination with normosthenuria and normal force of urinary stream. No recurrent stricture, urethrocutaneous fistula, or penile curvature occurred. The cosmesis was satisfactory, and the results of urine routine examination was normal. CONCLUSION: Ventral urethroplasty for postoperative anastomotic stricture in patients with hypospadias is a simple and effective procedure.
