I had RP in December 2020 to remove a Gleason 9 cancer. At the three month point, my PSA was undetectable. I went in for a routine overall health check at four months, and the PSA came back at .021, so the oncologists recommended ADT and 40 sessions of salvage radiation. My incontinence had started really bad, but gradually and continually improved with kegels all the way through the radiation to the point that I was leaking only .1 to .2 ounces per day (which might have been just sweat since it was summer). However, at four months after radiation ended (11 months after RP), I suddenly started leaking again. First it was 5 ounces per day, then 10, and so on, as well as OAB symptoms. By 6 months post radiation (17 months post-RP), leakage was 40+ ounces per day. I was distraught and tried everything - many thousands of kegels, physiotherapy, and finally Botox injections into the bladder walls. My urologist finally convinced me to have an Artificial Urinary Sphincter (AUS) implanted, which I did 2.5 years after the RP. The AUS has been like a miracle. The OAB symptoms are almost totally controlled by taking Gemtesa once per day. Please understand, my trajectory is uncommon, affecting less than 5% of patients (so I was told). However, my urologist is superb, having written a chapter in a urology textbook on the AUS. Best of luck to you, and remember, the main thing has to be to defeat the cancer.
