Vascularization of vessel pedicle in hypospadias and its relationship to near-period complications

摘要

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.
