目的 分析尿道下裂尿道成形不同术式与术后尿道狭窄发生之间的关系。方法 总结１９８７ 年６ 月至１９９７ 年６ 月本院治疗的４３４ 例尿道下裂尿道成形术资料，术后合并尿道狭窄５０ 例，分析不同术式、狭窄发生部位及狭窄发生率之间的关系。结果 尿道口前移，龟头成形术（ ＭＡＧＰＩ）、Ｏｎｌａｙｉｓｌａｎｄ ｆｌａｐ 法（加盖岛状皮瓣技术） 的狭窄率为０，Ｍａｔｈｉｅｕ 法的狭窄率较低，为９ ．３ ％ ，而ＤｅｎｎｉＢｒｏｗｎ 与膀胱粘膜法的狭窄率较高，分别为２８ ．３ ％ 、３６．０ ％ 。结论 阴茎头、冠状沟型的尿道下裂尽量采用ＭＡＧＰＩ法；阴茎体型宜采用Ｍａｔｈｉｅｕ 法，而近端型宜采用Ｏｎｌａｙｉｓｌａｎｄ ｆｌａｐ 或Ｄｕｐｌａｙ＋ Ｄｕｃｋｅｔｔ法；只有当材料没有或缺乏时才考虑膀胱粘膜法。
Objective To analyze the relationship between different procedures of hypospadia urethra formation and urethral stricture. Methods The data of 434 cases of hypospadias treated in our hospital from June 1987 to June 1997 were retrospectively analyzed. The data of 50 cases with urethral stricture were analyzed retrospectively. The relationship between different operative procedures, site of stenosis and the incidence of stenosis were analyzed. Results The stenosis rate of urethral anterior displacement, glansoplasty (MAGPI) and Onlayisland flap method (with island flaps) was 0, and the stenosis rate of Mathieu method was 9. 3%, while the rate of stenosis of DenniBrown and bladder mucosa was higher, which was 28%. 3%, 36.0%. Conclusions MAGPI is the best method for the treatment of glaucoma and coronal hypospadias. The Mathieu method should be used for the penis size and the Onlayisland flap or Duplay + Duckett method should be used for the proximal type. The bladder mucosa method should be considered only when the material is lacking or lacking.
