Purpose: We present 2 variants of the penile disassembly technique for epispadias repair that refine some details of the Mitchell technique. In some cases the urethral plate retracts and shortens, and there may be poor vascularization at the most distal portion. In addition, when the neurovascular bundles of the separated hemicorporeal glanular bodies are intact, it is difficult to achieve excellent correction of dorsal chordee.
Materials and methods: Between 1995 and 1998 we performed the modified Mitchell technique in 11 boys 2 to 14 years old using 1 of 2 variants. For variant 1 the hemiglans and urethral plate remain connected by a small tissue bridge to avoid shortening the urethral plate and ensure a better blood supply. For variant 2 each corporeal body is dissected from the glans cap and neurovascular bundle to achieve complete mobility. This procedure enables ideal mobility of the corporeal bodies as well as curvature repair. When corporeal rotation was unsuccessful, we corrected persistent dorsal chordee using the Ransley corporotomy with corporostomy in 2 patients and with dermal grafting in 1.
Results: Mean followup was 17 months (range 6 to 30). Dorsal curvature was corrected in all cases. Cosmetic appearance was good. Complications included meatal stenosis and urethral fistula in 1 case each.
Conclusions: Our variants of epispadias repair may be good alternatives to the Ransley and Mitchell complete penile disassembly techniques.
