Preoperative Factors Affecting the Outcome of Single Stage Hypospadias Repair- An Observational Study

Background:Hypospadias is one of the commonest congenital anomaly in boys which requires either a single stage repair or staged repair. The success of the procedure depend upon the type, anatomy, experience of the surgeon, method of repair and preoperative hormonal stimulation. Aim: The aim of the study was to evaluate the various preoperative factors responsible for outcome of single stage repair in distal penile, mid penile and proximal penile hypospadias. Methods: There were 48 patients in this observational study which were divided into two groups. Group A comprised of 24 patients with glanular and coronal hypospadias while Group B comprised of 16 patients with distal penile, 5 mid penile and 3 proximal penile types with minimal chordae. All the 24 (50%) patients in group A underwent meatal advancement and glanuloplasty incorporated (MAGPI) repair while in group B 15 (31.25%) patients underwent Tabularized Incised Plate (TIP) repair and 9 (18.75%) patients underwent combined TIP and Mathieu’s repair. Results: Overall operative success rate observed in the study was 41 (85.41%) patients. In 7 (14.58%) patients urethrocutaneous fistula as a major complication occurred which included 1 patient in Group A and 2 patients with Distal Penile Hypospadias (DPH), 2 patients with Mid Penile Hypospadias (MPH) and 2 patients with Proximal Penile Hypospadias (PPH) in Group B. In 2 (4.16%) patients, mild meatal stenosis was noted which settled with meatal dilatation. Urethrocutaneous fistula (UCF) disappeared in 2 (4.16%) patients on follow up with regular urethral dilatation. Conclusion: MAGPI is the ideal procedure for glanular/coronal hypospadias. For distal penile hypospadias, TIP alone or combined TIP and Mathieu’s repair gives equally good results. Preoperative testosterone therapy reduces the incidence of complications in a single stage hypospadias repair.
