Hi Stu, in my very limited experience, (one case), perpetual incontinence immediately after surgery is not ‘normal’. Of course, any outcome depends on the skill of the surgeon, the state and staging of the tumour, how much was removed, the age of the patient and his general health prior to surgery.
All I can say is in my case, as oft repeated here, I bought a pack of 14 Tena light pads for the day my supra-pubic catheter was removed, and I have four left. A shame really, as if I had stuffed them down my knickers, I might not have suffered the three nocturnal accidents which occurred a week or two later! I now sleep on a map of Tasmania....
I am continent now, save the occasional dribble, which I may have had before....but maybe then it was not out of the end of my penis.....
Dad and daughter should contact the MacMillan/Prostate Nurse at the hospital where the surgery took place, and hopefully they will be able to offer some help and advice.
Best of luck and kind regards, John.
