A kidney stone is a solid, crystalline mass that forms in the kidneys when certain minerals and substances in the urine become concentrated and crystallize.
These stones can vary in size and composition, with calcium oxalate being the most common type.
Kidney stones can cause severe pain when they move through the urinary tract, leading to symptoms like intense flank or abdominal pain, blood in the urine, and urinary tract infections.
Treatment may involve pain management, hydration, and in some cases, medical procedures to remove or break up the stones.
