Barbagli G, Palminteri E, Guazzoni G, Cavalcanti A. Bulbar urethroplasty using the dorsal approach:
current techniques. Int Braz J Urol. 2003
Mar-Apr;29(2):155-61.
INTRODUCTION: The use of flaps or grafts is
mandatory in patients with longer and complex strictures. In 1995-96 we
described a new dorsal onlay graft urethroplasty. Over time, our original
technique was better defined and changed. Now this procedure (also named
Barbagli technique) has been greeted with a fair amount of enthusiasm in Europe
and in the United States.
SURGICAL TECHNIQUE: The patient is placed in normal lithotomy position, and a
midline perineo-scrotal incision is made. The bulbar urethra is then free from
the bulbo-cavernous muscles, and is dissected from the corpora cavernosa. The
urethra is completely mobilized from the corpora cavernosa, it is rotated 180
degrees, and is incised along its dorsal surface. The graft (preputial skin or
buccal mucosa) or the flap is fixed and quilted to the tunica albuginea of the
corporal bodies. The right mucosal margin of the opened urethra is sutured to
the right side of the patch-graft. The urethra is rotated back into its
original position. The left urethral margin is sutured to the left side of the
patch graft and to the corporal bodies, and the grafted area is entirely
covered by the urethral plate. The bulbo-cavernous muscles are approximated
over the grafted area. A 16F
silicone Foley catheter is left in place.
COMMENTS: Dorsal onlay graft
urethroplasty is a versatile procedure that may be combined with various
substitute materials like preputial skin, buccal mucosa grafts or pedicled
flaps.
