Retrospective analysis of the results obtained by using Mathieu and TIP urethroplasty techniques in recurrent hypospadias repairs.

Abstract:

OBJECTIVE:To determine the effect of Mathieu and tubularized incised plate (TIP) urethroplasty techniques on the outcome of repair in recurrent hypospadias. MATERIAL AND METHODS:A total of 78 patients who had undergone surgical correction by either Mathieu or TIP urethroplasty after unsuccessful hypospadias surgery were enrolled in this study. Cases were divided into two groups according to the operation technique performed. Surgical success rate of the techniques and the prognostic significance of age, type of diversion used, caliber and length of new urethra, and the number of previous operations were analyzed statistically. RESULTS:Mathieu and TIP urethroplasties were performed in 57 and 21 patients, respectively. No statistically significant relation was found between the groups for age, length of new urethra created, caliber of the urethra, urinary diversion used, mean operation success rates and number of previous operations. From within-group analysis, Mathieu urethroplasty was found to have a statistically significant relationship with the number of previous operations (P=0.025, Mann-Whitney U-test). CONCLUSIONS:Age, length and caliber of new urethra, and diversion type used seem to have no effect on the success rate of Mathieu and TIP urethroplasty in recurrent hypospadias restoration. The success of the Mathieu operation diminished proportionally to the number of previous failed surgeries.
