title: [External sphincterotomy in neurological patients: A monocentric experience].
abstract: OBJECTIVE
  The aim of this study was to assess the feasibility, efficacy and tolerance of Greenlight™ and Holmium sphincterotomy for treating detrusor-sphincter dyssynergia.
  
  
  METHODS
  All men treated with this two techniques between may 2012 and june 2015 were analyzed. Preoperative evaluation included kidney ultrasound scan, urodynamic, retrograde and voiding urethrocystography. Postoperative assessment was composed of a post-void residual volume measurement when the urethral catheter was removed and 1 year after the procedure, a retrograde and voiding urethrocystography at 3 months and telephonic Likert scale questionnaire.
  
  
  RESULTS
  Twelve patients were operated with Greenlight™ and 12 with Holmium. Eleven had a memocath urethral stent preoperatively. Post-void residual volume median for both techniques was 285 cc preoperatively vs 137.5 cc postoperatively (P<0.001). Likert scale global satisfaction was 75%. Five stenosis (20.8%) were observed within a median of 4 months.
  
  
  CONCLUSIONS
  Greenligth™ and Holmium procedures are efficient techniques with low morbidity. However, superiority toward monopolar incision remains to be demonstrated through complementary studies.
