you're lucky you passed it that fast. I lived with one for 10 days before they finally went in to get it out. Unfortunately they pushed it back into my kidney and couldn't get it out. They then installed a stent that went in my pee-pee thru my bladder and ureters in my kidney. I had to have that thing in for a week with this piece of monofilament fishing line hanging out of my manhood. After a week I had the "pleasure" of pulling it out and then pee'd the stone out the following morning.
