Hey Turtlepin,
I'm new to this forum, but not to incontinence, going on my 7th year now. I've got what the urologist calls a neurogenic bladder with overflow incontinence, which just means that it will ill completely before letting loose.
When I was in the hospital back in '07 for my 3rd back surgery, I had to be cathed to drain my bladder, because even with the incontinence, it wouldn't drain on it's own for almost 2 weeks. Anyway, the nurses would come in to do it for me and use one of those bed urinals, you know the 32 ounce ones. Well, I would regularly fill one of those and then part of another before my bladder was completely empty. It was usually around 35 to 40 ounces. So I can believe you when you say you can hold 1.7 something liters.
My nurses couldn't believe that I could hold that much. I guess they don't normally see someone with our problem very often.
I too use cloth diapers just for this reason as well. I hadn't found a disposable yet that could handle one of my floods.
