I didn't have that problem, per se, but I *did* notice that my bladder drained much more quickly and easily post-op, so maybe my experience will help a little anyway. Basically, in the past it was like using a hose... even with a good hose, it takes a bit for the fluid to move through it. Now, without the "hose" and the urethra much shorter as well as wider, I basically pee in a gush that floods out very fast and then done.
(If you're wondering - yes, that was just tons of fun immediately post-op, when I had no control over the flow yet AND no idea where the "stream" [stream, heck, it was more like Niagara!] was going to go.)
