Dorsal Dartos Flap Prepared Before Urethroplasty, Less Bleeding of Operation: A New Perspective on Hypospadias.

Background: The benefits of preparing the dorsal dartos flap before urethroplasty were investigated.

Materials And Methods: Patients with coronal, subcoronal, and distal penile hypopadias without severe cordee who underwent surgical repair between October 2016 and September 2020 were included in the study. Tubularized incised plate urethroplasty technique was applied to all patients. The patients were divided into two groups: In Group 1, the dorsal dartos flap was prepared after urethroplasty, which is the commonly used technique today, and sutured on the neourethra. In Group 2, the dorsal dartos flap was prepared before the post-degloving urethroplasty. The amount of bleeding, the duration of the surgery, and the complications between the two groups were recorded and compared.

Results: Twenty-two patients who could be followed up for at least 3 months were examined. There were 10 patients in Group 1 and 12 patients in Group 2. A statistically significant difference was found between the amount of bleeding of the operation in the two groups. Duration of operation, hematoma, infection, skin necrosis, or glanular dehiscence were not observed in any patient.

Conclusions: Preparing the dorsal dartos flap, before urethroplasty significantly reduces the amount of bleeding. This may be a new modification alternative in hypospadias surgery.
