Which symptoms are likely associated with kidney stones?

Severe back pain and hematuria are classic symptoms associated with kidney stones. When stones form in the kidneys or travel through the urinary tract, they can cause intense pain, often referred to as renal colic, which is typically felt in the back and sides, possibly radiating to the lower abdomen or groin. This pain arises due to the obstruction and irritation of the urinary tract by the stone.

Hematuria, or the presence of blood in the urine, often accompanies kidney stones. The stones can scrape against the lining of the urinary tract, causing bleeding, which results in blood being detected in the urine. This combination of severe pain and hematuria is commonly seen in patients suffering from kidney stones and is a strong indicator for diagnosis.

Other options present symptoms that are not typically associated with kidney stones. Low fever and reduced appetite can suggest infections or inflammatory processes, but they are not definitive for kidney stones alone. Dizziness and fatigue may be due to several factors unrelated to renal calculi. Frequent urination and high blood pressure could imply other urinary or cardiovascular conditions, but they are not hallmark symptoms of kidney stones.
