OBJECTIVE: To report our experience in managing complex anterior urethral strictures with a dorsally/dorsolaterally placed penile/preputial vascularized flap, and to discuss the advantages of this procedure over a traditional ventrally placed flap.
PATIENTS AND METHODS: Between 1995 and 1999, 40 patients (mean age 40.5 years) with recurrent strictures of the pendulous and/or bulbar urethra were treated with longitudinal penile/circumpenile flap substitution urethroplasty. Nineteen patients underwent dorsal placement of the flap as an onlay (DO), whereas 21 patients had a ventral onlay (VO). Five patients needed inferior pubectomy to facilitate high proximal placement of the flap.
RESULTS: Both groups had statistically similar ages, number of previous interventions, stricture site, length and follow-up. After a median follow-up of 27.5 months, the stricture recurred in three (24%) of the VO and two (11%) of the DO groups (P > 0.05). One patient in the VO group required surgical closure of the urethral fistula. Flap pseudo-diverticulum and/or sacculation with postvoid dribble occurred in six patients in the VO and none in the DO group (P = 0.01).
CONCLUSIONS: Dorsal placement of the pedicled flap is anatomically and functionally more appropriate than the traditional VO placement. DO preputial/penile flap urethroplasty is a versatile procedure and can be applied even for long anterior urethral strictures, including reconstruction of the meatus and high proximal bulbar strictures.
