Background Hypospadias surgery has been continuously evolving, although there is no single technique which can be said to be perfect and suitable for all types of hypospadias. Tubularized incised plate (TIP) urethroplasty (Snodgrass procedure) is presently the most common surgical procedure performed for distal penile hypospadias (DPH). The aim of this study was to compare the outcome of TIP urethroplasty using Dartos flap (DF) and spongioplasty as second layer in DPH. Methods A total of 30 patients of DPH were repaired using TIP urethroplasty with DF or spongioplasty as second layer from January 2017 to June 2018. Out of 30 patients, TIP with DF was done in 15 patients (group A) and TIP with spongioplasty was done in the remaining 15 patients (group B). Preoperative mean age and weight were comparable in both groups. Postoperative complications, namely, postoperative edema, residual chordee, urethrocutaneous fistula (UCF), meatal stenosis and final cosmesis, were recorded. Results In both groups, complications included postoperative edema (Gp A-1Gp B-1), residual chordee (Gp A-1, Gp B-1), UCF (Gp A-3, Gp B-4), meatal stenosis (Gp A-1, Gp B-5) and poor cosmesis (Gp A-3, Gp B-4). Wound infection was managed with appropriate antibiotics, and meatal stenosis responded to calibration in five patients. Although it seems that DF has a better outcome clinically, the difference between the two techniques was statistically not significant. Conclusion DF as an additional cover to TIP is associated with an acceptable complication and has good cosmesis compared with spongioplasty; however, the difference is not statistically significant. Data are available on reasonable request. All data relevant to the study are included in the article or uploaded as online supplemental information. All the relevant data related to the study have been included in the article, although if needed, raw data will be made available.

Dartos皮瓣与海绵体成形术在Snodgrass尿道成形术治疗阴茎远端尿道下裂中的比较


背景 尿道下裂手术一直在不断发展，尽管没有一种技术可以说是完美的并适合所有类型的尿道下裂。管状切开板（TIP）尿道成形术（Snodgrass 手术）是目前治疗远端阴茎尿道下裂（DPH）最常见的外科手术。本研究的目的是比较使用 Dartos 皮瓣 (DF) 的 TIP 尿道成形术和海绵体成形术作为 DPH 中第二层的结果。方法 2017年1月至2018年6月，采用TIP加DF尿道成形术或第二层尿道海绵体成形术修复DPH患者30例，其中30例患者中，15例行TIP加DF尿道成形术（A组），TIP加尿道海绵体成形术。其余 15 名患者（B 组）。两组的术前平均年龄和体重相当。记录术后并发症，即术后水肿、残余腱索、尿道皮肤瘘（UCF）、尿道口狭窄和最终美容情况。结果 两组并发症均包括术后水肿（Gp A-1、Gp B-1）、残余腱索（Gp A-1、Gp B-1）、UCF（Gp A-3、Gp B-4）、鼻道狭窄（Gp A-1、Gp B-1）、尿道狭窄（Gp A-3、Gp B-4）、 A-1、Gp B-5）和美观性较差（Gp A-3、Gp B-4）。使用适当的抗生素治疗伤口感染，五名患者的校准对鼻窦狭窄有反应。尽管 DF 在临床上似乎具有更好的结果，但两种技术之间的差异在统计学上并不显着。结论 DF 作为 TIP 的附加保障，与海绵体成形术相比，并发症可以接受，并且具有良好的美容效果；然而，差异在统计上并不显着。可根据合理要求提供数据。 与研究相关的所有数据都包含在文章中或作为在线补充信息上传。与该研究相关的所有相关数据均已包含在文章中，但如果需要，将提供原始数据。
