Hi. I had the aus800 installed last year august. It failed. Dec had the pump.moved to other side.fail. Feb 22 had it all removed. Cuff eroded into urethra causing infection. 8 weeks each time to recover. Feb cath in for 8 weeks. Do you know where they cut you? SO painful. You won't sit for weeks. Good luck. I hope yours works. Pump should be activated at 4 weeks. Get a good donut to sit on before surgery.
