After my one year prostatectomy and diverticulotomy, it was suggested that I have another urodynamic study due to the fact that I could still retain quite a bit. I can go for hours without feeling the sensation that I have to pee. When I do it's sudden with little control. The study indicated that everything was fairly normal with the exception that I have a very large bladder. Has anyone been given a similar diagnosis? Could that be some of the reasons for my incontinence issues? Would my situation fall into the underactive definition? I didn't have good control before my surgery which could also add to the problem. I am nearly 71 years old, and do not want anymore invasive surgeries or devices implanted. I have learned to manage with diapers. Maybe that's a cop out, but it works. I'm curious if anyone else has similar issues, or is mine unique?
