title: Dorsal on-lay preputial graft urethroplasty for anterior urethra strictures repair.
abstract: OBJECTIVE
  To report the long-term results and evaluate the effectiveness of the dorsal on-lay preputial graft urethroplasty in patients suffering from anterior urethra strictures.
  
  
  METHODS
  A total of 21 male patients, mean age 46.3 years (range 17-67), with anterior urethral strictures, underwent the dorsal on-lay preputial graft urethroplasty during the last 8 years, from October 1997 to September 2005. Strictures were located in bulbar urethra in 16 patients and in penile urethra in the remaining 5. The aetiology the stricture was traumatic injury of the anterior urethra in 12 patients and iatrogenic in 9 patients. A direct vision dorsal urethrotomy and the insertion of an urethral Foley catheter right before the procedure, facilitated the corpus spongiosum dissection and the preparation for urethroplasty. A voiding cystogram was performed on the day of urethral catheter removal to exclude extravasation and estimate the postoperative result.
  
  
  RESULTS
  Mean follow-up time has been 49.9 months (range 6-95) and the outcome was favourable in 15 patients (71.43%). There were 3 recurrences in penile urethra strictures managed conservatively and three in bulbar urethroplasties, treated with internal urethrotomy followed by urethral dilatations.
  
  
  CONCLUSIONS
  Our results indicate that dorsal on-lay urethroplasty using preputial graft is an easy to learn and perform procedure, and offers the patient durable results with rather minimal complications.
