Hi all. For those with an in-dwelling catheter, have you found some types/ brands to be better than others?

I have an ongoing problem with sediment, despite having neither UTIs or stones, and I'm wondering if it's the catheter itself. All my urologist can suggest is going up a size in catheters (from 14 to 16), but I worry that this will just increase the irritation and sediment.

The sediment also tends to increase around each period, but I'm not sure what the connection is there.
