Urethral Reconstruction in Boys with Classical Bladder Exstrophy

Abstract

A total of 24 boys with classical bladder exstrophy underwent initial urethral reconstruction at our hospital between 1975 and 1982. Penile reconstruction in male patients with classical bladder exstrophy includes penile lengthening, release of the dorsal chordee and reconstruction of the urethra. The former 2 procedures are performed during the primary bladder closure and urethroplasty usually follows bladder neck reconstruction. A modified Young urethroplasty was done in 22 of the 24 patients. Preputial pedicle grafts of free full thickness skin grafts were used for urethroplasty in 2 boys with insufficient penile skin. Fistulas requiring surgical revision developed after urethroplasty in 21 per cent of the patients. A prior osteotomy was associated with a decreased fistula rate. The cosmetic and preliminary functional results of the penile reconstruction were assessed by parental interviews. The definitive assessment of the penile reconstruction will be determined when these boys reach sexual maturity.
