I too was more afraid of the catheder than anything else. I echo some of the advice given, with a couple of more ideas:
I had a large master bathroom with a long counter that helped. I set things up on the counter - you have to rinse the bags with a bleach solution after changing. I quickly got into a routine for this. Also, I had a chair next to the toilet which helped in emptying and changing bags. Get some of those baby wipes for cleaning around the cath. I also used my wife's old walker next to the bed to hold the night bag. My only problem was I didn't have enough adhessive strips to hold the tubing on my thigh - cathe secure. Some use velcro straps for this. Removing the cath was not painful at all, just weird.
I'm now three weeks post catheder, and am mostly dry. For the last two days I have only used one of my wife's senitary napkins just in case of a drip. Friday will be 5 weeks post surgery, and I'm feeling great - walking 2 miles a day and wanting to do more, but being careful to hold back. Good luck!
