title: Holmium:YAG laser for treatment of strictures of vesicourethral anastomosis after radical prostatectomy.
abstract: OBJECTIVE
  Strictures of the vesicourethral anastomosis (VUA) following radical prostatectomy tend to recur. We used the holmium:YAG laser for treatment of recurrent stricture of the VUA. We evaluated the technique and its efficacy.
  
  
  METHODS
  In 10 patients, the Ho:YAG laser was used with a 365-mum fiber at a setting of 2 J and frequency 10 to 20 Hz, creating a deep incision of the scar tissue at the 6 o'clock position. This was followed by a vaporizing resection of the remaining scar tissue between 3 and 9 o'clock. We aimed to vaporize up to well-vascularized surrounding tissue. Retrospectively, the charts were reviewed for hospital stay, voiding complaints, recurrence of stenosis, complications, and flow rates. The mean follow-up was 18 months.
  
  
  RESULTS
  There were no operative complications. After removal of the catheter, all patients could void without difficulty. No re-treatment was needed for recurrent stenosis. Any existing irritative voiding complaints or incontinence did not change after treatment. In all patients, the flow pattern improved: the mean maximum flow rate increased, and the mean postvoiding residual volume decreased.
  
  
  CONCLUSIONS
  The Ho:YAG laser seems to be a safe and effective treatment for first or recurrent strictures of the VUA after radical prostatectomy.
