How are kidney stones managed?
Kidney and ureteric stones, collectively known as urinary stones or urolithiasis, are solid crystalline deposits that form within the urinary tract. They develop when certain substances in urine—such as calcium, oxalate, uric acid, or cystine—become concentrated and crystallize. Over time, these crystals can grow into stones that vary in size, from tiny grains of sand to large, obstructive masses.
Several factors contribute to stone formation. Dehydration is the most common cause, as low urine volume allows minerals to concentrate. Dietary habits, including high intake of salt, animal protein, and oxalate-rich foods, can increase risk. Medical conditions such as gout, hyperparathyroidism, and recurrent urinary tract infections also play a role. In addition, genetic predisposition and certain medications may increase susceptibility.
Symptoms depend on the size and location of the stone. Small kidney stones may pass unnoticed, while larger stones can cause severe pain when they move from the kidney into the ureter. This pain, known as renal colic, is typically sharp, sudden, and felt in the flank or lower abdomen, often radiating to the groin. Other symptoms include blood in the urine, nausea, vomiting, frequent urination, and burning during urination. Fever and chills may indicate an associated infection, which requires urgent medical attention.
Diagnosis is usually made through imaging studies such as ultrasound or CT scans, along with urine and blood tests. Treatment depends on stone size, type, and symptoms. Small stones often pass spontaneously with increased fluid intake and pain control. Larger or persistent stones may require medical therapy, shock wave lithotripsy, ureteroscopy, or surgical removal.
Prevention is a key aspect of management. Adequate hydration, dietary modifications, and treatment of underlying conditions significantly reduce recurrence. With proper care and lifestyle changes, many individuals can successfully prevent future kidney and ureteric stones.
