Objective: To assess erectile dysfunction in patients with prostate cancer undergoing surgery by radical prostatectomy, laparoscopic prostatectomy or robotic prostatectomy. Material and methods: Systematic Review of literature based on a search strategy (2000-10) in MedLine, Embase, Cochrane Library, CRD, ECRI, and Hayes. Mesh terms used were "Prostatectomy", "Prostatic Neoplasm", "Transuretral Resection Prostate", "Impotence" and as free terms "erectile dysfunction" and "prostatectomy". Studies included patients with prostate cancer underwent by prostatectomy radical with open surgery (retropubic), laparoscopic or robotic surgery. Results: Ten observational studies with moderate quality and 29 case series with low quality were selected. Observational studies showed lower percentages of erectile dysfunction after intervention in the patients underwent robotic surgery (3-51%). Radical surgery (36-91%) and laparoscopic surgery showed higher values of impotence. In the studies that compared surgery versus radiotherapy, the results were better for radiotherapy (3-72% erectile dysfunction). In the case series, lower percentages of erectile dysfunction were shown in patients underwent to robotic surgery (22%), the following was for laparoscopic surgery (40%) and open radical prostatectomy (41.4%). Conclusions: This result should be considered with caution because of the low methodological quality of the studies included. However, the different surgical techniques assessed showed similar effects in the two types of studies included and we found that robotic surgery presented lower percentages of sexual impotence.
