Summary
This study is evaluating the utility of an intracavernosal injection of botox for penile rehabilitation in men undergoing a nerve sparing radical prostatectomy, a procedure which causes erectile dysfunction in over two-thirds of patients. Who is it for? You may be eligible for this study if you are an adult male aged 40 to 75 years old who has been diagnosed with prostate cancer, and is undergoing unilateral/bilateral nerve sparing radical prostatectomy. Study details Participants will be randomly assigned to receive an intracavernosal injection of either botox or normal saline immediately at the end of their surgical procedure (radical prostatectomy). Participants will also be asked to complete questionnaires regarding their sexual function and quality of life at several timepoints during the 12 months following the prostatectomy. It is hoped that findings from this study will help determine the utility of botox in penile rehabilitation for men with prostate cancer undergoing radical prostatectomy.
