【 摘 要 】

Despite advances in technical and surgical approaches, erectile dysfunction (ED) remains the most common complication among prostate cancer survivors, adversely impacting quality of life. This article analyzes the concept and rationale of ED rehabilitation programs in prostate cancer patients. Emphasis is placed on the pathophysiology of ED after diagnosis and treatment of prostate cancer to understand the efficacy of rehabilitation programs in clinical practice. Available evidence shows that ED is a transient complication following prostate biopsy and cancer diagnosis, with no evidence to support rehabilitation programs in these patients. A small increase in ED and in the use of phosphodiesterase type 5 (PDE5) inhibitors was reported in patients under active surveillance. Patients should be advised that active surveillance is unlikely to severely affect erectile function, but clinically significant changes in sexual function are possible. Focal therapy could be an intermediate option for patients demanding treatment/refusing active surveillance and invested in maintaining sexual activity. Unlike radical prostatectomy, there is no support for PDE5 inhibitor use to prevent ED after highly conformal external radiotherapy or low-dose rate brachytherapy. Despite progress in the understanding of the pathophysiologic mechanisms responsible for ED in prostate cancer patients, the success rates of rehabilitation programs remain low in clinical practice. Alternative strategies to prevent ED appear warranted, with attention toward neuromodulation, nerve grafting, nerve preservation, stem cell therapy, investigation of neuroprotective interventions, and further refinements of radiotherapy dosing and delivery methods.
