阴茎包皮岛状皮瓣一期修复阴茎阴囊型和会阴型尿道下裂

目的探讨阴茎包皮岛状皮瓣一期修复阴茎阴囊型和会阴型尿道下裂的手术方法. 方法 1997 年～2003年,对31例尿道下裂患儿,其中阴茎阴囊型21例、会阴型10例,按照尿道下裂的不同病理解剖,进行阴茎包皮岛状皮瓣设计、移位和尿道成形修复手术.阴茎包皮岛状瓣最长7.5 cm,宽1.5～1.8 cm. 结果修复后阴茎外形良好,不臃肿、无扭曲,尿道开口达到正常解剖部位,排尿正常或接近正常.术后发生尿瘘11例,其中阴茎阴囊型6例、会阴型5例,经修补后痊愈. 结论阴茎包皮岛状皮瓣一期修复阴茎阴囊型和会阴型尿道下裂是一种实用、有效的手术方法.

ONE STAGE REPAIR OF SCROTAL AND PERINEAL HYPOSPADIAS WITH PREPUCE ISLAND FLAP

Objective To explore an effective method to repair penile-scrotal or perineal hypospadias in one stage with prepuce island flap.Methods Different prepuce island flaps were designed according to the different pathological anatomy of the penile-scrotal or perineal hypospadias. The prepuce island flaps were thus translocated and sutured to form the urethra. Thirty-one cases of hypospadias (21 cases of peinil-scrotal type, 10 cases of perineal type) were repaired with prepuce island flap.The biggest length and the width of the prepuce island flap were 7.5 cm and 1.5-1.8 cm respectively.Results All the cases resulted in a good contour of the penis and a normal anatomic position of urethral meatus without any redundancy or tortuosity. The urination was perfect and acceptable.Conclusion One stage repair of penile-scrotal or perineal hypospadias with prepuce island flap can be considered as an acceptable effective surgical technique.
