Popis: Introduction and Objectives Erectile dysfunction (ED) usually occurs in the surgical treatment of prostate cancer (PC). Since many patients are reluctant to discuss ED when facing PC treatment, some patients choose non-nerve sparing radical prostatectomy and later seek for ED treatment. We had 5 cases of patients who were treated with combination therapy of intracavernous injection (ICI) therapy of prostaglandin E1 (PGE1) and PDE5 inhibitors for ED after non-nerve sparing RP and retrospectively investigated the effectiveness of the combination therapy. Material and Methods The mean age when the patients had RP was 65.4 years. Following the 2016 National Comprehensive Cancer Network (NCCN) risk classification guidelines, 2 patients had high risk, and 3 had intermediate risk. The mean period up to the introduction of ICI from the date of RP was 40.2 months (12-120 months). All patients were given PDE5 inhibitors 3-4 weeks prior to ICI therapy. Erection was evaluated by the induction of ICI of 20 μg of prostaglandin E1 (PGE1), using Erection Hardness Score of 1 to 4; a score of 3 or 4 was classified as successful. Self-injection regimen was introduced by the physicians after the evaluation, and a total of 5 patients were tested. Results The response was Grade 1 in 1 patient, Grade 3 in 3 cases, Grade 4 in 1 case. The effectiveness rate was 80%. Penile self-injection therapy was adopted by 4 patients, and IIEF-5 and SHIM score improved from 5.3 to 17.5 and 4.3 to 14.8, respectively. No drug adverse effect was observed in the 4 cases. Conclusions Combination of ICI therapy and PDE5 inhibitors can be a candidate for ED patients who unluckily chose non-nerve sparing radical prostatectomy when treated prostate carcinoma.
