Kidney stones are NOT contagious.
More Info: Kidney stones develop when more minerals and acid salts are present in the urine than water to dilute them, forming crystals that separate from the urine. Urine contains a chemical that naturally inhibits the buildup of stone formation, so the cause of a kidney stone is the urine’s inability to perform this task. Kidney stones are not contagious.
Types of Kidney Stones
Calcium stone is the most common type of kidney stone. Calcium stones are usually combined with other minerals such as oxalate and phosphate. Several factors can increase the oxalate or calcium in urine including foods and metabolic disorders.
Struvite stone, also called the infection stone, by its very name sounds as if it could be contagious. Struvite stones are a result of a urinary tract infection or a kidney infection neither of which is contagious.
Uric acid stone develops when the urine contains too much acid. High acid content in the urine could be due to consuming too much meat, not enough fluids, and gout.
Cystine stones are rare and are caused by cystinuria, a condition that runs in families which causes the kidneys to excrete too many amino acids.
