Abstract
OBJECTIVE:
Because of the complexity of the abnormalities and limited options for reconstruction of failed hypospadias, creating a neourethra presents a challenge to surgeons. We reviewed our experiences with staged urethroplasty strategies to repair the penis of failed hypospadias.
MATERIALS AND METHODS:
We retrospectively reviewed 56 consecutives patients following multiple unsuccessful hypospadias repairs from 2010 to 2016. Patients were divided into the following two groups based on their penile conditions and urethroplasty procedures: staged buccal mucosa graft Bracka urethroplasty (group1) and two-stage urethroplasty with additional buccal mucosa graft augmentation of the dorsal urethral plate (group2).
RESULT:
Median follow-ups were 26.5 months (12-59 months) and 28.6 months (14-59 months) in the group 1 and group 2. After the second stage, three patients (11.1%) in group 1 and two patients (6.89%) in group 2 did not have a meatal opening at the top of the glans. Three patients (11.1%) in group 1 and 4 patients (13.79%) in group 2 had urethrocutaneous fistulas. One patient (3.70%) in group 1 and no patients in group 2 had meatal stenosis. Two patients (6.89%) in group 2 and no patients in group 1 had urethral strictures; all patients with strictures were cured using dilations, so follow-up surgeries were not required. No patients in either group had signs of diverticulum or residual chordee. Three patients (11.1%) in group 1 and 4 patients (13.79%) in group 2 needed reoperations.
CONCLUSION:
Failed hypospadias repairs were often due to the underestimation of the penile conditions at the prior surgery. The results indicated that two-staged strategies were preferred for treating complex situations during the intermediate period of our study. Staged buccal mucosa graft Bracka urethroplasty and two-stage urethroplasty with additional buccal mucosa graft augmentation of the dorsal urethral plate severed as reliable approaches in complex hypospadias cases and could improve the overall success rate.
