title: [Radiotherapy influence, about results of the InVance(®) male sling in men with stress urinary incontinence].
abstract: OBJECTIVE
  To study impact of previous radiotherapy on urodynamic parameters, continence and complication rate, after prosthetic implantation with InVance® device.
  
  
  METHODS
  We included 106 patients between August 2004 and March 2009. We stratified urinary incontinence according to pads daily used, in grade I (one to two pads), II (three to four), or III (more than four or condom catheter use). We compared one group of 24 patients with previous radiotherapy (R) to 82 control patients (T) without one. Follow-up was made at three and six postoperative months and then annually. Results were classified into: no leaks, improved or failure.
  
  
  RESULTS
  Mean follow-up was 14.8 months (median=12.8) in group R and 12.4 months (median=8.8) in group T. At three postoperative months, continence was achieved in 62.5% patients from group R and in 77% patients in group T (P: ns). At 12 months, results on continence were respectively 52.6% in group R and 63.2% in group T (P: ns). Six patients were explanted because of an infection (5.7%), among which two in group R (8.3%) and four in group T (4.8%). Infection was significantly linked to operative time (P: 0.02).
  
  
  CONCLUSIONS
  Previous radiotherapy has no impact on urodynamic parameters and continence, on short- and mid-term analysis, after implantation of a bone-anchored suburethral sling with InVance® device, preferentially patients with mild to moderate incontinenec urinary.
