I had to visit the emergency room about a week ago with a stone blocking the flow of urine from my bladder. I often have stones and pass them with little difficulty, but this one got stuck, and I had to have a catheter inserted. I do not normally have a problem passing urine. The doctor started me on Flomax, but after four days I had to stop. I was dizzy, disoriented, and my vision blurred. Even walking was difficult. My doctor says that my stone problem is due to insufficient emptying of the bladder although, to my knowledge, either from x-ray or my feeling their passage, the stones have originated in my kidneys. He is advising me to have a procedure called a TURP, which sounds pretty unpleasant. I do not have a problem with UTI's and he claims that the Green Laser treatment is inferior to TURP. Either one seems to be a rather radical option for a condition that, if indeed I have it, causes me little trouble. I would rather deal with the occasional stone (two or three a year) than run the risk, which is not negligible, of incontinence or sexual dysfunction. I will, of course, seek a second opinion (maybe a third) before deciding on this surgery, but I am wondering if TURP is, in fact, an appropriate treatment option for retention. Many thanks. It's great to have some help with this and good to connect with others who experience the same condition. (Fortunately, in this case, the catheter expelled during my sleep and the stone came out via the usual route.)
