Combined Mathieu and Snodgrass urethroplasty for hypospadias repair: a prospective randomized study.

OBJECTIVES

To evaluate the outcomes of combined Mathieu and Snodgrass urethroplasty for distal hypospadias repair and to compare them with the two techniques separately.

METHODS

Between January 2006 and February 2009, patients with distal hypospadias were prospectively randomized to undergo one of the three following urethroplasty techniques: Mathieu urethroplasty, Snodgrass urethroplasty or a combination of the two. Operative time, intraoperative, early and late postoperative complications were reported for each procedure.

RESULTS

101 patients were included in this study. The Mathieu technique was used for 30 patients, Snodgrass repair was carried out in 37 patients and 34 patients underwent the combined technique. Operative time ranged from 43 to 120 min. Eight patients developed urethrocutaneous fistulae. Meatal stenosis was encountered in five cases. Thirty-seven patients had rounded meatus, while a slit-like urethral opening was found in 64 cases.

CONCLUSIONS

In our hands, the combined Mathieu and Snodgrass urethroplasty technique provided a better cosmetic outcome than the Mathieu technique with no incidence of meatal stenosis as seen with the Snodgrass technique.
