Here are some products I use or familiar with.
New Image Two-Piece Urostomy Pouch
I like the two piece for a number of reasons, you can access to the stoma, you can turn bag for a better position

Backside
New Image™ Soft Convex CeraPlus™ Skin Barrier – Tape
This particular style is more flexible and sticks better.


Adapt Cerra Ring 8805
I add this piece for better seal and gives me more days with bag. It is very flexible and I enlarge the hole because my stoma is larger.

This is my bag of choice for a numbeer of reasons, I like the length of the tube as you can cut if needed, the antireflux design, the open and close system, the hook for easy hanging.
Bard Urinary Bedside Bag

154002 Bard Urinary Bedside Bag, 2000 mL, Anti-Reflux, 1 Hook Hanger.
