are a topic near and dear to my heart as I’ve had three myself. The
medical term for stones is nephrolithiasis (nephro - kidney, lith -
stone, sis - condition). Stones or calculi, from the Latin for pebble,
can form and stay in the kidneys (renal calculi) or move down the
ureters, the tubes connecting the kidneys to the bladder (ureteral
calculi). Stones may also be found in the bladder.
