Hi, I hope I can help and I can only relate to you my own experience. You and your father will have to make your own decision, but I hope that you will find my experience useful.
I am currently recovering from radical prostatectomy. I had the operation on Sept 1st. I will try to put your mind at rest.
My diagnosis on June 16th after my biopsy was a Gleason score of 7 (3+4) on the right side and the left side was clear. I was also told that the cancer was touching the nerve bundle but just on one side. There were only two options available to me, radiotherapy or the radical surgery. I didn't really fancy six months of hormone treatment followed by 28 days of radiotherapy, especially as I was told by the consultant that if it "didn't work", a prostatectomy as a follow-up would be very unlikely indeed as it is much more difficult to safely remove a prostate when it has been "shrivelled" by the hormone treatment and radiation. In addition, the side effects such as diarrhoea and fatigue as a result of the radiation did not really appeal to me. Although the consultants did not influence my decision either way, once I had made it, they did all say that they agreed that the prostatectomy was likely to provide the most successful outcome in my case.
I went for a pre-op assessment towards the end of August and went in for the op at 7am on Sept 1st. I was out of theatre and on the ward just before midday. By this time the catheter was in place that drained directly into a bag at the side of my bed, and I had a morphine pump that I was able to control via a push button to control any pain when necessary.
I was discharged the following day at 2pm after having the catheter connected to a bag attached to my leg. I was given precise instructions on how to drain the bag etc. I had to wear compression stockings (and will have to for another ten days) and also have to inject anti-clotting agent into my stomach every day, BUT this is very easy to do and does not hurt at all.
Pelvic floor exercises are a bit of a moot point with regard to speed of recovery, but I started doing them six times a day for a month before my op. I am still doing them now, six of ten repetitions every day.
Ten days after my op, I went back to the hospital to have the catheter removed. I had to stay there and drink water and pass urine so they were satisfied that I could pee properly.
Now for the good bit: I was totally "dry" at night after my first day at home and have been since! I am still wearing a pad but only 11 days after having the catheter out, with the exception of "stress leakage" as a result of sudden movement putting pressure on the weakened bladder, I am also now dry during the day. I put this mainly down to the Pelvic Floor Exercises!
Tomorrow I have an appointment with the urology nurse to check my progress and give me advice etc. Next week I am having my PSA blood test which I hope will be as close to zero as possible. I will see the consultant for the results and prognosis in about three weeks.
So, that is my story so far. I cannot advise you which route your father should take and as Lyn has said, you do need to talk to the experts . . . . but also find out from men who have had all the various treatments as only they have personal experiences of their journeys. In the end, it is your father's decision and his alone. I wish him all the best and yourself too.
Good luck,
Glen
