I had a catheter twice for about 3 months each time. It does take a bit of getting used to, but it has been an important part of my recovery. Changing the bag is a two person job in my opinion, emptying it is simple and will become second nature. The key to changing the bag in my opinion is for you to hold on tightly to the catheter whilst your husband changes the bag. Because believe me you don’t want him to pull on the catheter!
In my experience the community nurses are great and very helpful, hopefully they will come out and get you sorted. The most important thing is to drink plenty of fluids, keeping it flushed through is the best way of avoiding problems. Wishing you the best of luck in your recovery 💐
