Kidney Stones
Cálculos renales
Also: Piedras en el riñón (regional variant)
What it means
A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor, but sometimes a stone may get stuck in the urinary tract, block the flow of urine and cause great pain. The MedlinePlus encyclopedia says the main symptom is severe pain that starts and stops suddenly, which may be felt in the belly area or side of the back. A doctor diagnoses a kidney stone with urine, blood, and imaging tests. MedlinePlus gives nephrolithiasis as another name and lists renal calculi among the alternative names. In Spanish the term is cálculos renales.
