I've had stones twice now. The 2nd time, they passed through but the 1st was the worst. I had the Iodine X-Ray scan to see what was going on but there was an infection in the kidney so the consultant said he needed to look inside as he could not see the number of stones.
This involves a procedure called Cystoscopy and luckily you are asleep for this. The camera goes down the end of your ..cough..cough...cough.. through to the bladder and onto the kidney to see where the stone is located. If there is a blockage and the consultant in my case thought it won't come out on it's own, he inserted a stent similar to the one's used to widen the Aorta. This allows the stone to move freely and exit in it's own time.
The pain when you go for your first leak after sugery, I can't put into words. I was stood on tip toes with my fingers embedded into the tiles.

The nurse said after 'localised trauma'.
Had the stent in for 5 weeks which caused problems as usually, the body holds fluids back in the kidney before passing them onto the bladder. With the stent there, it was like an open valve causing the bladder to fill up faster. A couple of times I was driving back from work and nearly had an accident because of being stuck in traffic.
I hope you get everything sorted. If you had the scans/X-rays this weekend, hopefully they will call you in soon to either check that the stone has made it's way out naturally or to book you in to sort it out.
All the best,
Adam.
