Before you leave the hospital after your surgery you will be give a list of "do's and dont's." Follow them to the letter! Remember, this is a pretty major surgical procedure. The rest of my advice is from my own experience and what I learned from other's advice.
1. Plan on living in a recliner for at least a week. Easier to get up out of a chair than a flat bed. Get fresh batteries for the TV remote! Purchased a small garbage can to hold my Cath bag by the side of my chair.
2. Get out of the recliner often. I would once an hour and walk laps around the island in my kitchen. Walk often! Avoid stairs. Walking will help your body get rid of the gas they pumped in your body ( caused me shoulder pain for several days.)
3. Drink, drink, drink!! Lots of water/juices. Avoid caffeine and alcohol. You need to flush the blood from your bladder. Keep an eye on the color of the urine in the catheter bag. If it's red, drink more.
4. But a pair of "breakaway" pants like the basketball players wear. Easier to put your pants on around your catheter tube than running the tube down your pants leg. One guy's wife did the same with his undershorts. She cut both sides and attached Velcro strips. I bought boxer briefs which extended down the leg longer and help support Cath tube. Bought them one size larger than normal.
3. Follow lifting restrictions! About a month after my surgery I decided to clean my garage. Didn't lift anything heavy but repetitive lifting of light items caused some pretty intense pain.
4. Take your medications as prescribed! I only needed pain medication for two days, some get by with only Tylenol.
5. You might go days before having a bowel movement. I thought I might explode. Don't force anything, it will happen!
6. I put a patio chair in the shower. With the cath, easier to shower sitting than standing.

Hope others will add their helpful advice. Good luck!
