title: Acceptance of and discontinuation rate from erectile dysfunction oral treatment in patients following bilateral nerve-sparing radical prostatectomy.
abstract: OBJECTIVE
  Assess acceptance of and discontinuation rate from erectile dysfunction (ED) treatment in patients after bilateral nerve-sparing radical retropubic prostatectomy (BNSRRP).
  
  
  METHODS
  We analyzed acceptance and discontinuation data of 100 consecutive, age-comparable, preoperatively self-reported potent BNSRRP patients who at the discharge from the hospital received a phosphodiesterase type 5 inhibitor (PDE5-I) prescription. Patients were informed of the pharmacokinetic properties of the available compounds and the option of on-demand versus rehabilitative therapy. Thereafter, patients did not receive any specific counseling throughout the entire follow-up period and freely decided to use or not use any ED therapy. Complete preoperative data were obtained on hospital admission and included a medical and sexual history and the International Index of Erectile Function (IIEF). The IIEF was completed every 6 mo postoperatively, and patients participated in a semi-structured interview about the treatment adherence at the 18-mo follow-up.
  
  
  RESULTS
  Forty-nine (49%) patients freely decided not to start any ED therapy (group 1). Of the remaining patients, 36 (36%) opted for an as-needed PDE5-I (group 2), whereas 15 (15%) decided to use a daily PDE5-I (group 3). At the 18-mo follow-up, the overall discontinuation rate from both treatment modalities was 72.6% (eg, 72.2% vs. 73.3% in group 2 vs. group 3; p=0.79). Treatment effect below expectations was the main reason for treatment discontinuation, followed by loss of interest in sex due to partner's causes.
  
  
  CONCLUSIONS
  Almost 50% of BNSRRP patients freely decided not to start any ED treatment postoperatively. Roughly 73% of patients who started therapy eventually discontinued it.
