Comparative Study of Modifying Meatal Advancement Glandular with Release Chordi versus Snodgrass Surgical Methods Regarding the Repair of Distal Hypospadias

Hypospadias is one of the most common congenital anomalies of the external genitalia of boys. No single technique can be recommended for the repair of hypospadias in its various forms. We aimed to compare modify meatal advancement glandular with release chordi versus Snodgrass surgical methods in the repair of distal hypospadias.

In this study, conducted from Apr 2018 to the end of Sep 2020, all boys who underwent one of the two methods of Snodgrass and modify meatal advancement glanuplasty with release chordi in Imam Khomeini and Abuzar Hospitals of Ahvaz, Southern Iran, were enrolled.

Forty-five patients underwent Snodgrass (group S) and 55 patients underwent modified meatal advancement glandular with release chordi (group M). The mean age of patients and duration of surgical wound healing in the two groups did not differ significantly. There was no significant difference between the two groups in terms of complications, including Bleeding, Hematoma, Meatus stricture, Wound infection, detachment of the wound edge, chordi after surgery, Balanitis and Urethral stricture but the incidence of fistula in patients undergoing Snodgrass repair was significantly higher than the group modify meatal advancement glandular with release chordi (P<0.05).

The method of modify meatal advancement glandular with release chordi compared to Snodgrass method is associated with fewer complications due to surgery, although further studies are recommended.
