Introduction: We sought to compare the surgical outcomes of hypospadias repair with correction of inguinal pathology using a single penile incision vs. conventional approach using two incisions.

Methods: This is a retrospective study that reviewed all patients who underwent concurrent surgical repair for both hypospadias and inguinal pathologies between January 2003 and November 2015. Patients were classified into Group A, conventional (inguinal or scrotal and penile incision) approach; or Group B, single penile incision approach. Baseline characteristics, including age, degree of hypospadias, type and laterality of inguinal pathology, operative time, and surgical outcomes, were collected. Between groups, variable comparisons were analyzed using Mann-Whitney U-Test and Fisher-exact test. Statistical significant set at <0.05.

Results: Seventy-six patients (Group A: 40; Group B: 36) were eligible for study. Baseline characteristics of both groups were comparable, with no significant statistical difference. Overall mean
operative time for Group A was 139.3 ± 56.2 minutes, while Group B was 107.8 ± 46.7 minutes (Z=2.6; U=470.5; p=0.009). Two patients in Group A and two patients in Group B had testicular
ascension, all of which also had hypospadias-related complications (p=1.0). Hypospadias-related complications in Group A included seven urethrocutaneous fistulae and two repair dehiscence. Eight
urethrocutaneous fistulae, one urethral stricture, and two repair dehiscence occurred in Group B (p=0.448). Surgical outcome appearance in both groups were comparable, with no statistically
significant difference (p=0.466).

Conclusions: Single penile incision for both hypospadias repair and correction of inguinal pathology is a feasible technique and comparable to the conventional approach, with similar surgical outcomes and shorter overall operative time.
