Kidney stones are diagnosed and treated by the Urology Division of Premier Medical Group. Kidney stones (calculi) are hardened mineral deposits that form in the kidney. They originate as microscopic particles of crystals and develop into stones over time. The medical term for this condition is nephrolithiasis, or renal stone disease.
Crystals and kidney stones may form when an imbalance of minerals occurs in the urine. About 1 in 10 Americans will suffer from kidney stones in their lifetime. Historically, men have stones three times as often as women, but this ratio has decreased over the last decade.
