2 years post successful robotic surgery, never had an issue of bed wetting until 3 months ago. I sometimes take a ambien to sleep better and on 3 occasions in the last 2 months had a wet spot when I awoke. On each occasion I did have a few glasses of wine, however I have had the wine on other nights that I did not have an issue. Is this a pelvic floor issue that I need to strengthen? I have not mentioned this to the doctor yet. I thought I was past all this.
I do still have my prostate, but like you I have had the same problem after starting Zytiga. I do use a medicine to help me sleep. It would seem like I would loose control of my bladder at night very randomly, sometimes soaking the diaper. To me this made it impossible to travel. I would wear adult diapers to bed. My M.O. was not very helpful on this front, I went back to my Urologist who ran some tests.We discussed a medicine I could take at night called Nocdurna, they need to watch your sodium level monthly on this medicine, but it does work completely for me. We have moved now to another city and I have found a new M.O. also who I feel listens to me.
Best of luck to you!
