That kidney stone you've been ignoring could be behind your recurring UTIs

Dear Doctor Roach: Five years ago, I was diagnosed with a kidney stone while getting an ultrasound for a different reason. A CT scan was ordered, which showed that I had a conglomerate of small stones within a calyceal diverticulum in the posterior mid-pole of my left kidney. My urologist at the time said it wasn’t in an area that was amenable to shock wave lithotripsy or a stone removal with a scope.
