A kidney stone, also known as a renal calculus. Kidney stones typically leave the body in the urine stream, and a small stone may pass without causing symptoms. This leads to pain, most commonly beginning in the flank or lower back and often radiating to the groin. Risk factors include being overweight, certain foods, some medications, and not drinking enough fluids. The diagnosis is usually based on symptoms, urine testing, and medical imaging.
An average of 52 members are effected every year in Sweden.
Treatment is often required for pain control from kidney stones as they pass. The consumption of ample fluids helps facilitate the passage of kidney stones, but even with plentiful fluid intake, most people require some type of medications for pain control.
