Renal colic
Renal colic
Renal colic is a sudden, severe pain in the kidney area, presenting as sudden, intermittent or continuous severe colicky pain in the kidney or flank region. Some patients may also experience radiating pain, which spreads to the lower abdomen, perineum, inner thigh, and other areas. Patients may toss and turn, finding it difficult to sleep. Most patients with renal colic experience unilateral kidney pain, while a small number may have symptoms of bilateral renal colic. Renal colic is usually caused by upper urinary tract stones, especially ureteral stones. In addition, kidney inflammation, kidney tumors, tuberculosis, necrotic tissue within the kidney, blood clots after kidney biopsy, ureteral polyps, and other foreign bodies, as well as vascular obstruction in the renal arteries and veins, can also trigger renal colic. Once symptoms of renal colic appear, immediate medical attention is required.
