© 2018 AEU Introduction: Given the high prevalence of erectile dysfunction in male population between 40-70 years old and the effect of radical prostatectomy on this domain, it is important to perform a baseline study. Material and methods: Prior radical prostatectomy, erectile function has been assessed prospectively in 112 prostate cancer patients using the erectile function (EF) domain of the International Index of Erectile Function (EF-IIEF), Erectile Hardness Score (EHS) and a penile doppler ultrasound (PDUS). Comorbidities and Charlson index were collected. The EORTC QLQ C-30 and PR-25 tests were administered. Results: According to EF-IIEF questionnaire, 50.9% of patients showed normal EF and EHS grade 3-4 erection was achieved in the 75.9%. PDUS was normal only in 28.6% of patients and 51.8% showed arterial insufficiency. We found a significant association (P < .0001) between categorized EF-IIEF (normal, mild/moderate/severe) and the EHS value. Between PDUS (normal vs. pathologic) and EHS (3-4 vs. 1-2) statistically significant association (P = .005) was found. Just 35.3% of patients with EHS 3-4 showed normal PDUS. Correlation between the PDUS and the EF-IIEF (≥ 26 vs. < 26) was statistically significant (P = .043). Moreover, only 38.6% of patients with EF-IIEF ≥ 26 had a normal PDUS. Conclusions: In order to predict EF recovery after surgery, global assessment is required. Solely self-administered tests are not enough. In this baseline study, PDUS can play an important role.
