Passed a 5mm several weeks back (after ER visit) but have a 3 stuck in ureter just above bladder for 15 days+.  Doc says ureteroscopy is necessary if it doesn't pass soon.  Most sites say it's safe but stent worries me.  Anyone have experience with a stent?  I've been drinking my water for a month, bouncing on mini-trampoline, etc. but no dice on the list smaller one.  Pain not terrible but uncomfortable.  A hot bath each afternoon helps a lot.
