隐匿阴茎不同术式的疗效比较

目的 探讨隐匿阴茎不同术式的疗效.方法 回顾性分析1986-2007年手术治疗219例隐匿阴茎患儿临床资料.年龄3～15(10.3±2.4)岁.术前测量阴茎外露长度0.5～3.0(1.9±0.5)cm,其中重度93例,中度126例.采用Johnston术34例,Devine术42例,改良Devine术125例,Brisson术18例.比较4种术式患儿术后阴茎长度增加的差异. 结果 Johnston术、Devine术、改良Devine术和Brisson术患儿术后阴茎外露增加长度分别为(1.8±0.4)、(2.0±0.5)、(2.1±0.4)和(2.3±0.4)cm,组间差异有统计学意义(F=13.1,P<0.001).Devine术、改良Devine术和Brisson术效果优于Johnston术.4种术式术后发生顽固性阴茎皮肤水肿患儿分别为8、5、6和2例. 结论 隐匿阴茎的形成与阴茎皮肤浅筋膜发育异常有关.改良Devine术式疗效良好,术后并发症少.

Comparison of different surgical techniques for treatment of concealed penis

Objective To compare the effects of different surgical techniques for treatment of concealed penis. Methods A retrospective review of 219 patients underwent surgical correction of concealed penis between 1986 and 2007 was performed. The mean age was (10.3±2.4) years(3-15 years). The penile length was (1.9±0. 5)cm(0. 5-3. 0 cm)before operation. Ninty-three patients were the severe degree of concealed penis. The others were the moderate degree. All patients under-went operation with different techniques, including Johnston's technique in 34, Devine's technique in 42, modified Devinds technique in 125 and Brisson's technique in 18. The increased length of penile af-ter operation was compared among the 4 groups with different surgical techniques by statistical meth-od. Results The postoperative increased length of penile in Johnston's technique, Devine's tech-nique, modified Devine's technique and Brisson's technique was (1.8 ± 0. 4) cm, (2. 0 ± 0. 5) cm, (2.1±0.4)cm and (2.3±0.4)cm respectively. The difference was significant by ANOVA test (F=13.1,P<0. 001). Devines technique, modified DevineSs technique and Brisson's technique were better than Johnston's technique considering the increased length of penile. The complication of severe penile lymphedema of 4 groups developed in 8, 5, 6 and 2 patients respectively. Conclusion Modified De-vine's technique has the satisfactory increasing of penile length for treatment of concealed penis and less complication rate after operation.
