目的:探讨改良Snodgrass术治疗尿道下裂的临床疗效。方法:回顾性分析2008年1月至2016年10月收治尿道下裂病例212例,其中94例行改良Snodgrass术,即增加1根丝线用于缝合,便于术后拆除尿道板缝线;118例行传统Snodgrass术。改良法采用术后第10天拆除尿道板缝线。比较两种手术成功率、术后并发症情况。结果:改良Snodgrass术组和传统Snodgrass术组手术成功率分别91.49%、81.36%,其差异有统计学意义(P<0.05),切口感染、尿瘘、尿道狭窄等的发生率:改良Snodgrass术组分别为4.26%、6.38%、2.13%,传统Snodgrass术组分别为12.71%、16.10%、2.54%。切口感染和尿瘘的发生率差异有统计学意义(P<0.05),尿道狭窄的发生率差异无统计学意义(P>0.05)。结论:改良Snodgrass术可以提高手术成功率,降低术后切口感染和尿瘘的发生率,有临床推广价值。
Objective: To investigate the clinical effect of modified Snodgrass on hypospadias. Methods: A retrospective analysis of 212 cases of hypospadias was performed from January 2008 to October 2016. Among them, 94 cases were treated with modified Snodgrass technique, that is, one silk thread was added for suturing to remove the urethral sutures; 118 cases Line traditional Snodgrass surgery. Modified method using the urethral plate sutures removed after 10 days. Compare the success rate of two operations, postoperative complications. Results: The successful rates of modified Snodgrass and conventional Snodgrass were 91.49% and 81.36% respectively, the difference was statistically significant (P <0.05). Incidence of incision infection, urinary fistula and urethral stricture were significantly higher in modified Snodgrass group 4.26%, 6.38% and 2.13% respectively. The traditional Snodgrass group was 12.71%, 16.10% and 2.54% respectively. Incision infection and urinary fistula incidence was significantly different (P <0.05), the incidence of urethral stricture was no significant difference (P> 0.05). Conclusion: Modified Snodgrass can improve the success rate of surgery and reduce the incidence of postoperative incision infection and urinary fistula, and has clinical value of popularization.
