DW be thankful you have that string. My doc didn't leave a string on the stent and had to run some type of grabber up to get the stent with no pain meds. Big as that grabber was I could piss a marble if it ever makes it to my bladder. By the way don't piss the doc off before he gets your stent out. That was one of the stupidest thing I ever did. Oh yeah, doc is gonna pull that sting like a pull cord on a push mower.
