Is there a leg bag that works with a urostomy bag?

[HDTVman3668]

I have tried some leg bags. I can connect them, but my urine won't flow into the leg bag. It seems like you have to put a catheter into the leg bag in order to overcome some valve that is in the leg bag.
I have read that some urostomy folks wear leg bags. I would appreciate knowing how to identify a leg bag that will connect to a urostomy bag and then accept urine.

Have you tried contacting your supplier? They might have received some feedback from other customers. I have an ileo, so am limited to experience with it. But, I do know that the folks at Parthenon have been quite helpful over the years. Here is their website link: https://parthenoninc.com/
I hope you find a solution soon.
