Objective To evaluate the features and advantages of Mepitel as dressings for treatment of hypospadia. Methods A total of 77 one-slage urethroplasty were performed by a single surgeon between July 2007 and October 2008.35 cases used Mepitel as bundled dressing (group Mepitel), 42 cases had nylon gauze dressing(group nylon). All cases with varying degree of clubbedpenis. The surgical methods included MAPGI, Onlay,Duckett,Mathieu,Snodgrass and Duckett + Duplay. The parameters (penis time-consuming, postoperative demolishing the dressings time-consuming, releasing pain, wound exudate, Penis skin scar and complication) were observed between two groups. Results There is no difference between two groups in dressings bind thne-consuming( P > 0.05) and complication( P > 0.05). There were statistical differences in demolishing the dressings time-consuming(P<0.01), releasing pain(P<0.01), wound exudate(P <0.01) ,and Penis skin scar( P < 0.05). Conclusions Mepitel has the great advantage of small damage, pain small and easy-to-op-erate. It is worth of popularizing.%目的 探讨医用透明硅胶膜(Mepitel)作为尿道下裂手术后阴茎包扎敷料的特点和优势.方法 2007年7月至2008年10月作者对35例尿道下裂手术患儿采用Mepitel作为术后阴茎包扎材料,对42例尿道下裂手术患儿采用尼龙纱布作为包扎材料.77例患儿均伴不同程度阴茎下弯,均行一期尿道成形术,手术由同一名医师完成,手术方式包括MAPGI、Onlay、Duckett、Mathieu、Snodgrass以及Duckett+ Duplay术等.比较两种材料包扎阴茎所需时间、拆除包扎时间、拆除时疼痛程度、拆除后创面残留分泌物、术后阴茎瘢痕以及并发症等方面的差异.结果 两组阴茎包扎时间差异无统计学意义[ (2.44±0.83)min vs(2.22±0.60)min,F=5.511,t=1.322,P=0.191)].拆除包扎时间差异有统计学意义[(1.22±0.67)min vs (4.85±2.90)min,F=22.228,t=-7.864,P =0.000)].拆除包扎后创面残留分泌物:Mepitel组6例,尼龙纱组19例,差异有统计学意义(x2=6.873,P=0.009).拆除包扎过程中患儿疼痛评分:Mepitel组优于尼龙纱组[(3.37±1.78)分vs(5.79±1.97)分,F=0.726,t=-5.588,P=0.000)],术后并发症:Mepitel组6例,尼龙纱组12例,差异无统计学意义(x2=1.392,P=0.238).术后3个月阴茎外观基本无瘢痕:Mepitel组28例(80％),尼龙纱组22例(52.4％),差异有统计学意义(x2=6.396,P=0.011).结论 Mepitel作为尿道下裂手术后阴茎包扎敷料具有损伤小,痛苦小,易操作的优点.
