Wow... your husbands story sound eerily familiar
I had a very similar thing happen to me on one of my laser cystoscopy sessions. I had a 10mm stone stuck in the l3-l4 region of my ureter, and there was no way I was going to pass it. Extreme pain, nausea, vomiting, hydronephrosis, sharp pains radiating into my groin, the whole bit. This was pretty early on in my kidney-stone career, but this particular surgery turned out to be quite pivotal (I DO have a point, so keep reading).
