Overview
What Are Urinary Stones?
Urinary stones — also called kidney stones or renal calculi — are hard deposits made of minerals and salts that form inside the kidneys or urinary tract. They can affect any part of the urinary system, from the kidneys down to the bladder.
When stones move through the urinary tract, they can cause severe pain, blockage, and complications. Early diagnosis and appropriate treatment are essential to prevent kidney damage.
