Purpose:To evaluate the clinical data and treatment outcomes of 3 different methods for redo hypospadias surgery.Patients and Methods:We retrospectively reviewed the data of 39 patients with redo hypospadias surgery between January 2010 and April 2019 at our clinic. A ventral preputial onlay flap, a preputial tubular flap, and a full thickness skin tubular graft were used in redo hypospadias surgery. We evaluated these methods regarding age, number, and type of previous repairs, catheter time, chordee, length of the urethral defect, operation time, complications, and follow-up results. T tests and Fisher's exact tests were used to compare differences between groups.Results:The mean operation age of the patients was 5.23 years. Sixteen patients had a single, 21 had 2, and 2 patients had 3 previous repairs. The position of the urethral meatus was perineal in 2, penoscrotal in 6, mid penile in 21, and distal penile in 10 patients. The initial repairs comprised 19 tubularized incised plates (TIP), 12 Mathieu procedures, 5 tubularized preputial flaps, 2 full thickness skin tubular grafts, and 1 onlay island flap repair. Eight full thickness skin tubular grafts, 18 onlay preputial island flaps, and 13 preputial tubular flaps were used for redo surgery. The success rate was 79.1%. Eight wound infections, 6 glans dehiscences, 13 fistulas, 12 meatal stenoses, and 5 urethral diverticulas were seen in the patients. The rates of these complications, Cystofix requirement, and reoperation were higher in the skin tubular graft group but this was not statistically significant (p> 0.05). One patient with graft contracture required a redo skin graft urethroplasty. The mean follow-up duration was18 months.Conclusion:Preputial tissue should be preferred in the presence of redo hypospadias surgery. In the absence of preputial tissue other tissues such as oral or buccal mucosa should be preferred instead of skin grafts.
