As has been mentioned earlier, a lot has to do with your physical condition before surgery and if you are willing and able to be somewhat active after the surgery to promote blood flow and therefore quicker healing to the affected area.
After knee ligaments surgery 30+ years ago, the advice was to rest and therefor the healing process took many months before weight bearing. Nowadays, after the same operation, the patient is encouraged to move their knee the next day allowing for weight bearing and quicker healing in a relatively short period. Post prostate surgery movement to a point, can have a very positive result for the patient.
Had RP surgery late April/13. Started walking a few days after surgery every day. Starting June 1st, began riding my touring bike every day. July 4th, my wife and I flew over to Europe for a 2 month, very strenuous cycle tour with all of our gear, through the Alps, camping 55 days straight. Had no problems at all.
For me, moderate to vigorous activity helped me heal quicker than I thought I would.
