OBJECTIVES:
We describe a technique for bulbar urethral reconstruction using a combined
dorsal plus ventral double buccal mucosa graft (BMG). METHODS: From March 2002
to June 2006, 48 men, mean age 35 yr, with bulbar strictures underwent patch
urethroplasty using a dorsal plus a ventral double BMG. Average stricture
length was 3.65cm (range: 2-10cm). The stenotic urethral segment was opened
along its ventral surface; the exposed dorsal urethra was incised in the
midline to create an elliptical area over the tunica albuginea where the dorsal
inlay BMG was placed and quilted to the corpora to augment dorsally the
urethral plate. Subsequently, the ventral onlay BMG was sutured to the urethral
lateral margins to complete the augmented urethroplasty. Finally, the
spongiosum was closed over the graft. Successful reconstruction was defined as
normal voiding without the need for any postoperative procedure including
dilation.
RESULTS: Mean follow-up was 22 mo (range: 13-59 mo). At the catheter
removal 3 wk after surgery, in three patients the voiding cystourethrography
showed a fistula, which recovered after a prolonged catheterization. Of 48
cases, 43 (89.6%) were successful and 5 (10.4%) failures with recurrence of the
stricture; 4 were treated with internal urethrotomy and 1 with a temporary
perineal urethrostomy.
CONCLUSIONS: Preliminary results with a combined double
BMG urethroplasty for severe bulbar stricture are encouraging. The double
dorsal and ventral graft may provide a simple and reliable solution to achieve
an adequate urethral lumen in selected patients.
