Secondary endpoints 9
- IIEF erectile function domain score combining the six IIEF questions related to erection (Q1-Q5 and Q15) measured at surgery, D0, M3, M6 and M9 postoperative
- International Index of Erectile Function global score measured at surgery, D0, M3, M6, M9 and M12 postoperative
- Quality of life score (EORTC QLQ - C30 and QLQ - CR29) measured at surgery, D0, M3, M6, M9 and M12 postoperative
- LARS score measured at surgery, D0, M3, M6, M9 and M12 postoperative
- Fecal Continence Score (Wexner score) measured at surgery, D0, M3, M6, M9 and M12 postoperative
- The number of patients presenting spontaneous erections under treatment at M3, M6, M9 postoperative and without treatment at D0, and M12 postoperative.
- The number of patients with or without regular psychological followup. A patient is defined as having regular follow-up if he visits a psychologist and/or psychiatrist once or twice a month
- Number of unused tablets during the study. The patient will be considered as non-compliant if tablet intake over the entire 10 months of treatment is < 80%.
