Background:
The ideal tissue for complex urethral reconstruction has yet to be determined, especially in patients with deficient preputium. The use of bladder mucosa as a free graft could be an alternative in these problem cases.
Methods:
Bladder mucosa graft urethroplasty was performed on 14 patients with penoscrotal or scrotal hypospadias. The mean age of the patients was 18.7 (range 14-23) years. Ten cases were subjected to primary urethral reconstruction while four cases had previous hypospadias repair.
Results:
Complete urethral replacement by the bladder mucosa tube was performed in six patients. Meatal problems occurred in two (33.33%) patients and proximal fistula formed in one (16.67%) patient. A bladder mucosa graft was combined with preputial or tunica vaginalis grafts distally in eight cases, and one patient in the tunica vaginalis group developed fistula at the anastomosis of the bladder mucosa and tunica vaginalis grafts. The overall complication rate was 28.6%.
Conclusions:
Our initial results showed that bladder mucosa grafts can be used successfully for urethral reconstruction especially when combined with preputial or tunica vaginalis grafts distally.
