My father in law just had trouble with a stone last 4 weeks and ended up bouncing in and out of hospital 3 times for pain relief and invetigations. Last weekend he was back so they took him to theater and put in a stent to keep to pipes open for a few weeks, I think they are hoping he will pass it, he thinks he may have on monday due to pissing blood again for a while and pain.
They are going to recheck in 4 weeks and remove the stent to see how things will go....no good then, they will blast it to smitherines with ultrasound shock waves and he will piss it out in a million pieces.
Apparently one of the most painful experiences available having kidney stones...sorry ceffo, hope it settles for you
