I don't know enough about these medications to comment. I do know that when my PSA score went from 4 to 11 my urologist did a biopsy in the local hospital and seemed hell-bent on doing robotic surgery.
I was scared and really had trouble thinking things thru. I ÓK'd the surgery and my prostate was taken out. For 2 weeks I had a lot of blood in my urine. I also (in the 2 weeks) had what appears to be my only "follow-up" with the urologist.
A year earlier my blood test showed that I had "low T". So I had monthly testosterone shots. But the shots seemed to have no effect. Then the urologist sent me for a blood test and my PSA had risen to 11. A final blood test (after 1 month of skipping the "T boosters) showed my PSA levels dropping but the biopsy showed my prostate was ridden with cancer.
Now some-one in a stronger position, either by way of money or something else, would probably ask the doctor if the T-shots caused the cancer. But when you are 70 years old and have been out of work for ten years because both your knees have to be "totally replaced" you become more careful what you say to some-one like my urologist. I was afraid that if I voiced my suspicions he would almost reflexively think that I was thinking "lawsuit".

So I kept quiet.

I was not given any medication for prostate cancer recovery and I stopped taking my usual daily dose of Tamsulosin. I figured that I was having enough trouble with bladder issues. I mean, I would be sitting more or less naked in front of my PC, and suddenly I would feel a warm wetness on my feet. I'd look at my penis and saw that once again I had decorated my bedroom floor with splashes of red and yellow. The blood tapered off to nothing after about 3 weeks, but I am still having issues with incontinence. My "robotic enhanced surgery" was done on June 16th. I still need to keep empty jars around my bed because I wake up having to pee but often, I know that I will not be able to stand upright before I start to piss on anything around me. Hence the 4 empty jars. Even without taking the Tamsulosin (aka Flomax) the only real control is to simply drink less liquids, especially an hour or so before going to bed.

Oh, since I have bored you all with TMI, I will also say that I have no sex drive post operation. I have tried to masturbate but even though some people claim you don't need an erection to reach orgasm, it has not worked so far for me. Maybe a few months down the road....

I appreciate having this bulletin board to read other men's experiences, and to share my own.
Thank you all.
