Kidney stones

Abdomen & Pelvis

Kidney stones (nephrolithiasis) are hard deposits that form inside the kidneys from minerals and salts in the urine. They can be present for a long time without causing symptoms, only becoming noticeable when they move or grow large enough to block urine flow. An MRI may show changes in the kidneys or urinary tract consistent with the presence of stones or their effects. Finding kidney stones early may allow for dietary and lifestyle changes that could help prevent them from growing or causing a painful blockage.
