I had the sling 1 year after RP. The incision in scrotum to rectum was uncomfortable with the sling and it failed . 1 year later a new dr put the AUS in and the incision was in same place. The cuff was put around the urethra under scrotum and the pump by testicle in scrotum and the fluid ballon was put by bladder. Yes it was/is uncomfortable at times . 1 thick pad normally gets me through the day . No pad at night needed I probably leak a little more than 3 1/2 years ago when I had the surgery. But I’m happy I had the AUS surgery.. a friend in his 70s I know had the AUS few months and is happy with it.
