I found that wearing shorts or such caused binding of the tube. I ended up taping the tube to my thigh and not wearing any underwear worked best. The large bag can be pinned to the side of the mattress. Some people, myself included slid a plastic or heavy metal coathanger between the mattresses and hooked the bag to that. The bag can be a aggravation to someone who tosses and turns in their sleep, but if they can sleep on one side, and get to choose the side of the bed so they face outwards, they should sleep better. My doctor and hospital sent home a prescription for stool softner, antibiotics, pain killer, bladder spasm meds,and gas pills. You may want to discuss with him beforehand what his procedure will be for you. The gas issue may take care of itself before you even leave the hospital. In my case, one good bout of bathroom privacy got it out and the bowels kicked in and started functioning normally, so it was a non-issue for me at least. Start out eating a lighter menu (but something that will add bulk) and slowly increase back to whatever is normal for him. Once you get past the first bowel movement, then your regular diet is ok. Cheap pj's that can be thrown out later worked well for me, we cut the leg up to the knee, to allow for the catheter bag and tubing to work properly and to get to the drain properly, also for dressing and undressing. Plan on him being tired easily, and needing lots of rest/seat time. But he should try to walk as much as possible, then get down and rest in between, if possible. I was told if I wasn't walking, I should be sitting or reclining and resting. Both will help with the recovery and healing process. He will probably be allowed to shower the day after getting home, and the dressings will probably come off then, usually there will be no wound dressing or care, other than gentle soap and water washing of the incision and drain wound. Hope some of this is useful for you in preparing.
