Nephrolithiasis is the medical term for kidney stones forming in the kidneys or urinary tract.
Symptoms may include severe pain in the side, back, lower abdomen, or groin, blood in the urine, nausea, vomiting, and pain when passing urine.
Imaging helps confirm that a stone is present, show where it is, and check whether urine flow is blocked or infection has developed.
CT is often the most sensitive test, while ultrasound may be used for selected patients or follow-up imaging.
Treatment depends on stone size, location, symptoms, and whether there is obstruction or infection.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
