Wow Skypilot.....so you did about a mile per day while the catheter was in and then once removed you were doing 4 plus miles 7 days per week?
Prior to surgery, I was walking 4-5 miles a day and running about
2 miles every other day. That and trying to get a few pounds down and doing situps, leg lifts and starting to do some of the keggle exercises.
After the surgery with the catheter in, I got up daily about
once every 2 hours, tried to walk around for at least 15 minutes each time. Having the catheter in took a bit of getting used to but actually not having to pee was oddly REALLY nice!. I worked up to about
10 minutes every hour by the third day, and was back outside and walking about
1 mile by the afternoon of the third day. I simply made a sache from a bathrobe, tied the bag to it (make sure the bag is well below your mid thing or else it won't flow out of the bladder easily), put it over my shoulder and walked around the neighborhood. First just back and forth in the circle, then out to the main roads up and down. Stepping up and down stairs and things was the hardest part. By the day I had the catheter removed (nine days) I was walking about
2 miles a day and had no problems of course getting to the hospital (driven, they don't want you driving with the catheter in). Once it was out, it was FREEEDOM!!!!
Walking progressed as expected and recovery followed. I sort of missed the bag a bit, it was terribly simple to just DRINK DRINK DRINK (tea, water, juices, no coffee or alcohol) and only fill the bag and then have it emptied (wife did it for the first 2 days since I didn't want to get up that often - god bless her) and then I just took it into the bathroom myself after that. It was fine. I ended up leaving the BIG 2L bag on most of the time as I was pushing about
8 liters a day and it was much easier to let that one fill and then empty. (pro tip, get yourself a 2-3L plastic drink pitcher at the store and just use that by the bed for the first few days to empty into and then dump the pitcher into the toilet. Hopefully, you'll have a helper for the first couple days. It's not a messy job, just an unusual one.
Also, as I was pushing so much fluid (recommended) I would set an alarm for the middle of the night to 1) empty the bag, as it will back up and that is uncomfortable and can be problematic)
2) take some of the pain meds, either the real ones or the ibuprofen and acetaminophen (you'll take both in serial most likely) KEEP ahead of the pain and the bag filling for the first 3-5 days.
