Purpose: This aim was to study the efficacy of a vacuum erectile device (VED) in rehabilitating the erectile function of patients undergoing nerve-sparing robotic-assisted radical prostatectomy. Materials and Methods: This prospective randomized study enrolled 35 prostate cancer patients from Thailand who had intact baseline erectile function and underwent nerve-sparing robotic-assisted radical prostatectomy. These patients were randomly assigned into either a study group which applied the VED for 10 min daily for 6 months or a control group which received no additional interventions. A 5-item version of the International Index of Erectile Function (IIEF-5) score, stretched penile length, and midshaft circumference were measured at 1, 3, and 7 months after surgery, respectively. Results: The mean patient age was 65.6 years, and the mean baseline IIEF-5 score was 22.91, which were comparable between the two groups. Three patients in the study group did not follow the VED protocol due to postoperative urinary incontinence. A per-protocol analysis revealed that the mean IIEF-5 score at 7 months was significantly higher in the study group compared to the control group (11.29 ± 7.47 vs. 6.61 ± 5.33, P = 0.047). The mean midshaft circumference was also higher in the study group (9.24 ± 1.43 cm vs. 7.91 ± 0.37 cm, P = 0.002). No statistically significant difference in the mean stretched penile length between the two groups was found. Conclusion: Early VED usage for penile rehabilitation following radical prostatectomy significantly improves IIEF-5 score and better preserves penile circumference but not penile length. A larger-scale multi-institutional study is required to validate these findings.
