The Penile Perception Score after distal hypospadias repair with tubularized incised plate and Mathieu

Abstract

Objective: The aim of this study was to evaluate the Penile Perception Score (PPS) after repair of distal penile hypospadias using tabularized incised plate (TIP) and Mathieu procedures.

Methods: A randomized controlled study was conducted at urology department from October 2013 to May 2014. It included 60 children who were divided into three groups: group A included 20 patients with distal hypospadias corrected using TIP; group B included 20 patients with distal hypospadias corrected using Mathieu; and group C included 20 children with normal male genitalia who were circumcised and considered as a control group.

Results: There were no statistically significant differences between group A and group B in urologists’ and parents’ average sum of PPS evaluation, but urologists’ satisfaction was more than parents’ satisfaction. The PPS for TIP was 8.43 and 7.80 for urologists and parents, respectively. The difference was significant. The PPS for Mathieu were 8.04 and 7.89 for urologists and parents, respectively, with no significance. There were no statistically significant differences between group A and group B in the postoperative evaluation by urologists and by parents in meatus, glans, shaft skin, and general appearance. There were complications in 10% of cases from group A in the form of fistula, in 30% of cases from group B in the form of fistula in 25% and meatal stenosis in 5%, and no complication in group C.

Conclusion: TIP showed better PPS score compared with Mathieu in hypospadias repair. However, the results of this study were not statistically significant. PPS was a good scale to evaluate hypospadias repair after surgery.
