Hey Ed,
We are glad you are with us. I haven't been on in several days, and am glad to meet you. I am a tremendous worrier, too. First of all, I think you made a good decision to have the robotic procedure. You get the cancer out, and the procedure is minimally traumatic, as surgeries go. I never had surgery before this, except for tonsils when I was a kid, and I was expecting excruciating pain. Didn't happen! The worst discomfort was the gas, and that'll go away when you walk. Sage advice on getting some dried fruit or prune juice as soon as you can after surgery. Constipation is no good-diarrhea is better, given the proximity of that area to the surgery site.
My old buddy Tamu was correct about bringing books to the hospital. Because of the after effects of the anesthesia, I couldn't concentrate that well, so listing to the radio or tv, or a cassette deck or an ipod was better than books. It is not too late to get the books Dr. Patrick Walsh's Guide to Surviving Prostate Cancer, and Dr. Peter Scardino's Prostate Book. These will help you more than you can imagine.
I have two remedies for the worries that I think are about like yours. One was information-reading in these two books helped so much. The other was Xanax. See if your primary care doc will prescribe it for you. Xanax is a benzodiazepine antianxiety med that also has antidepressant effects. The generic version actually worked better for me than the name brand. Don't stress about this stuff too much. It is not going to do you any good. Take the Xanax. My concept of a Higher Power is the God Who created everything. Remember God made us with benzodiazepine receptors in our brains, and God made pharmaceutical researchers to develop these things to help us. You won't need the Xanax after surgery, because the news will be good. As far as pain meds, after the stomach gas went away, all I needed was Darvocet which is a mild one with Tylenol in it.
Your numbers are highly hopeful and you will do fine. Walk, walk, walk to stay in shape.
The only other thing I can think of right now is to bring some pads with you to the hospital, either the disposable underwear or the men's guards pads. I used these even with the catheter in because sometimes I would leak around the catheter, especially with gas or No. 2 (too much information?). Also get the velcro strap thing to fasten the catheter tube to your thigh. You will be glad you did, so that there is strain relief on this tubing and it doesn't pull on the part that is in you. Also, get some Neosporin ointment (the clearish greasy kind-not the white creamy kind) or your local drugstore's store brand triple antibiotic ointment. You smear this on the catheter tube pretty thick, at the point where it goes into you. This provides a long-lasting lubricant that really makes having the dang thing a lot more comfortable.
All I can think of for right now. I'll right more if I think of something.
Best to you,
