What are the symptoms of kidney stones?

Symptoms of kidney stones include severe pain in the lower back or flank, hematuria, frequent urination, urgency, and difficulty urinating. In severe cases, it may cause infection or kidney damage, and you need to seek medical treatment in time. The specific symptoms may vary depending on factors such as the size and location of the stone and whether it causes obstruction.

The most typical symptom of kidney stones is severe pain, which often manifests as sudden cramps in the lower back or flank. The pain usually radiates to the lower abdomen or inner thigh and is difficult to relieve. Hematuria is also common, and the urine is visible to the naked eye as red, or an increase in red blood cells in the urine is found during examination. If the stone blocks the ureter, the patient will feel frequent and urgent urination, but the urine output may be reduced or even anuric, indicating that emergency medical treatment is needed. Some patients may also have fever, chills, and even tenderness in the lower back and discomfort in the kidney area due to infection caused by the stones. If the stones are not treated for a long time, they may damage the kidneys and lead to chronic kidney disease or renal insufficiency.

It is recommended that patients with kidney stones pay attention to their daily water intake. Adults are advised to drink more than 2-3 liters of water per day, which helps dilute urine and prevent stones from forming again. In terms of diet, high-purine and high-oxalate foods, such as animal offal, spinach and nuts, should be avoided, and salt intake should be reduced. If severe symptoms occur, treatment methods such as ultrasonic lithotripsy, extracorporeal shock wave or minimally invasive stone removal should be selected in time. Regular physical examinations can help detect small stones early so that reasonable treatment plans can be taken.
