The present study evaluated the relationship between the vascularization of vessel pedicle and the near-period complication by assessing the surgery effect and recognizing the blood supply of the material for urethra reconstruction and collected the follow-up of the hypospadias patients after the operation. We illuminated the prepuce by a lighting technique using cold light and then photographed, and recorded the distribution and the quantity of vessels. Then classified, analyzed and summarized the vascularization of vessel pedicle. Patients who were repaired by Duckett technique were followed up for 1-5 months after the operation. We classified vessel pedicle vascularization in hypospadias cases into four patterns based on the predominant blood vessels. The number of predominant vessels had no exact relationship to the meatal location. The incidence of fistula and stricture had no exact relationship to the number of predominant vessels. In conclusion, there is no exact congruent relationship between the types of vascularization with the meatal location. Vascularization of vessel pedicle had no exact relationship with urethral fistula or stricture.
本研究通过评估手术效果、识别尿道重建材料的血供情况，来评价血管蒂的血管化与近期并发症之间的关系，并收集了尿道下裂患者术后的随访资料。我们采用冷光照明技术照亮包皮，然后拍照并记录血管的分布和数量。接着对血管蒂的血管化情况进行分类、分析和总结。采用Duckett技术修复的患者术后随访1 - 5个月。我们根据主要血管将尿道下裂病例中的血管蒂血管化分为四种类型。主要血管的数量与尿道口位置没有确切关系。瘘管和狭窄的发生率与主要血管的数量没有确切关系。总之，血管化类型与尿道口位置之间不存在确切的对应关系。血管蒂的血管化与尿道瘘或狭窄没有确切关系。
