urinary tract stones
"Suffer from uric acid stones on an average of every 4-6 months.  Was given a prescription for Flomax last ER visit; filled it to keep on hand.  Two days ago had an attack and decided to try the Flomax.  Amazingly, the stone passed in an hour and a half instead of the next day!....This has never happened before and it really shortened the terrible pain which usually lasts many hours.  I will definitely try this next time I have an attack, which I KNOW will happen again."
