What are the symptoms of kidney stones?

Renal colic is usually a small stone with microscopic or gross hematuria and obvious percussion pain in renal area. When the pain attacks, the patient's face is pale, the whole body is cold sweating, the pulse is fast and weak, even the blood pressure drops, often accompanied by nausea, vomiting and abdominal distension and other gastrointestinal symptoms.

Small stones with smooth surface can be excreted with urine without obvious symptoms. Stones fixed in the renal pelvis and lower calyces without infection can also be asymptomatic. Even if large staghorn calculi do not cause obstruction or infection of renal calyces and pelvis, they may have no obvious symptoms for a long time, or have only mild renal discomfort or acid distension.

Hematuria is often accompanied by pain. Sometimes patients have no pain, only hematuria or minimal blood volume, the naked eye can not see. Most of the physical examination includes urine examination, and microscopic examination of the sediment after centrifugation of urine. If you see too many red blood cells, it means hematuria. Sometimes it is an early sign of kidney stones.

matters needing attention

Diet composition should be based on the type of stone and urine pH. Patients with calcium oxalate stone should avoid high oxalate diet and limit the intake of spinach, beet, tomato, nut, cocoa, chocolate and other foods. Calcium intake should be limited in patients with idiopathic hypercalciuria. Low salt diet, control sodium intake. People with high uric acid should eat a low purine diet, avoid eating animal viscera, and eat less fish and coffee.
