roberdc: recovery from prostate surgery was not disabling for me at 72 yrs old. Catheter was removed at 10 days and I actually was able to fully function thereafter "mentally". Slowly returned to walking, played a round of golf at 7 weeks and VERY strictly observed limited lifting direction, including light weight lifting, for 2 months.
Surgery does not have to be disabling if performed by an experienced surgeon. Many on this site have sought care at a recognized center of excellence. Continence recovery can be an issue (was not for me). ED is a separate issue.
this was intended to address your early fears.
this is a major surgery, I and many advise reading Surviving Prostate Cancer by Patrick Walsh, MD, and other resources such as the free Patient Guide available from the Prostate Cancer Foundation (pcf.org).
there is much to learn and consider, and you are at the beginning of this trip.
Best to you.
