I was diagnosis with knot on my prosproates and the doctor say he saw some tummors on my bladder. he removed the tummors and now I'm not able to pass my urine. I've been wearing a cathryl for 1 month. The doctor will remove it and have to re insert it because I can not urine on my own. He say he will probably have to do surgery. Is there any type suegery for the bladder. Pls advise Eddie
