Dorsal
onlay graft urethroplasty is a versatile procedure which may be combined with
various substitute materials such as preputial skin, buccal mucosa grafts or
pedicled flaps. Others substitute materials such as human urethral mucosa from
corpses or collagen matrix will be possible in future. The long-term results of
a wide series of patients showed a final success rate from 92% to 97%. Any kind
of substitution urethroplasty deteriorate over time, and in our series of
patients with an extended follow-up from 21.5 to 43 months the success rate of
dorsal onlay graft urethroplasty decreased from 92% to 85%. With regard to
substitute material concerns (buccal mucosa versus preputial skin) a long-term
follow-up is mandatory to establish if buccal mucosa is superior to foreskin as
urethral substitute material. At present, the authors currently use both
according to patient preference, status of the genital tissues or strictures
characteristics.
