title: Erectile dysfunction in anterior urethral strictures after urethroplasty with reference to vascular parameters.
abstract: BACKGROUND
  Relation of erectile dysfunction (ED) with urethroplasty has long been a subject of debate. Very few studies on subcontinent population are available in this regard and still rarer are studies assessing vascular parameters of ED following urethroplasty. The objective of the study was to assess the incidence and prevalence of ED in patients of urethral stricture disease, and to find out effect of urethroplasty on ED after six months of operation including vasculogenic aetiology after operation.
  
  
  METHODS
  From January 2014 to December 2015, 35 subjects underwent urethroplasty. They were assessed pre- and postoperatively by International Index of Erectile Function (IIEF-5) and Pharmacological Colour Doppler Ultrasonography (PCDU) for a period of 6 months.
  
  
  RESULTS
  Preoperative prevalence of ED assessed by IIEF was found to be 82.8%. Postoperative incidence of ED was 28.5% and new onset ED is 50%. There was no significant change in IIEF values and values of peak systolic velocity and resistive index of cavernosal artery over time.
  
  
  CONCLUSIONS
  There is significant prevalence of ED with urethral stricture. Despite significant postoperative incidence of ED after urethroplasty, the surgical procedure per se does not result in ED.
