Abstract

Aim: To present our modified Snodgrass technique (MST) and results in hypospadias repair in children.

Methods: Medical records of all hypospadias patients undergoing our MST repair at our center from July 2016 to October 2021 were reviewed. Our modifications of the Snodgrass technique consisted of an extension of the urethral plate incision up to the glans tip and the creation of one more intermediate protective layer from the corpus spongiosum. All patients were scheduled for calibration of the meatus 2 weeks after discharge and were followed up regularly at the outpatient clinic.

Results: 153 patients were enrolled with a median age was 3 years (range: 1 - 13 years). Distal and proximal hypospadias were presented respectively in 39.9% and 60.1% of the patients. In 9.8% of the patients, Baskin’s dorsal plication was carried out for persisted chordee > 300 after degloving. The median operative time was 90 minutes. The median postoperative hospital stay was 9 days. At a median follow - up of 34 months (range: 2 - 63 months), complications were recorded in 13.1% of the patients: urethral fistula in 6.5%, meatal retraction - 3.9%, recurrent chordee - 2.6%. No patient suffered from meatal or urethral stenosis.

Conclusions: Our MST can give a relatively low rate of urethral fistula and no incidence of meatal or urethral stenosis.
