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.
