A COMPARATIVE STUDY OF THE TWO PROCEDURES MATHIEU REPAIR AND SNODGRASS REPAIR FOR THE REPAIRING OF THE ANTERIOR HYPOSPADIAS

Background: The aim of this research work is to compare the time duration of operation and the frequency of difficulties in the procedures of the Snodgrass and Mathieu for the repairing of initial anterior hypospadias.

Methods: The duration of this study was from March 2014 to February 2018 in Arar Central Hospital Arar Northern Border Zone KSA.  80 patients were the participant of our study with primary anterior hypospadias and the children’s which were included in our study was from 2 to 10 years of age.  In our study only those patients were to be included who had never repaired their hypospadias and all those patients who had repaired their hypospadias previously were to be excluded from this study and also all those patients were also excluded from our who had significant chordee.  All the patients are to be distributed in two groups in which one group had Mathieu and group II is Snodgrass procedure (Tabularized incised plate (TIP), Urethroplasty). By frequent irrigation the stent was kept patent. Operative time duration for both the procedures was calculated and after the procedures completed, patients were to be follow up for the complications.    

Results: In this study we have studied 80 patients. We have divided the patients into two groups, group I was Mathieu repair procedure and Group II was Snodgrass repair procedure, so the Mathieu repair procedure were performed in 40 patients and the Snodgrass procedure were performed in the remaining 40 patients.  In the Snodgrass repair the cosmetic results were very good with a normal cut looking like meatus. In both the procedures wound breakdown and meatal stenosis was equal however in Mathieu procedure the proximal stricture and urocutaneous fistula were frequently seen. Meatal stenosis and wound breakdown was equal in each group whereas urocutaneous fistula and proximal urethral stricture were seen more frequently in Mathieu group.
