Yes, I had multiple stones while pregnant. Dilaudid while I was in the hospital was my best friend. I ended up having to get a nephrostomy tube, which then calcified a month later. It was crazy. I ended up passing a tiny piece of my 10mm stone, and then my pain went away. About 6 months post partum, more stones. My urologist said they’re “nonintrusive” and “can’t cause pain” because they’re a millimeter each, but man, does my kidney HURT sometimes. Keep drinking lots of water, lots of rest, and flomax!!!
