What is a common presentation of kidney stones?

A common presentation of kidney stones is flank pain accompanied by hematuria. This specific type of pain typically occurs when a stone passes down the ureter, leading to obstruction and irritation. Flank pain is often described as severe and can radiate to the lower abdomen or groin, depending on the location of the stone.

Hematuria, or blood in the urine, is frequently associated with kidney stones due to the irritation and damage they can cause to the urinary tract lining as the stones move. The combination of flank pain and hematuria serves as a classic clinical sign of nephrolithiasis (kidney stones) and can help distinguish it from other abdominal or pelvic conditions.

The pain associated with kidney stones can also vary in intensity and may be intermittent, often described as colicky due to the spasmodic nature of the obstruction. While the other options may represent different conditions or symptoms, the specific pairing of flank pain and hematuria is particularly indicative of kidney stones.
