Treatment of kidney stones can be divided into two parts, including symptomatic treatment and treatment of the stones themselves. Symptomatic treatment For patients who develop renal colic, nonsteroidal anti-inflammatory drugs, such as indomethacin and diclofenac sodium, can be selected to relieve pain, reduce ureteral edema caused by stones, and promote stone expulsion. Antispasmodic drugs, such as scopolamine, can also be used. If the symptoms of renal colic cannot be relieved by medication, or if recurrent pain occurs, ureteral stenting can be done to reduce the pressure in the renal pelvis, which can relieve the pain. Lithotripsy and lithotripsy are also more commonly used treatments. For stones smaller than 0.6 cm, if there is no obstruction in the urinary tract below the stone, lithotripsy is recommended as the preferred treatment. Lithotripsy treatment consists of drinking large amounts of water, more than 2,000 ml per day, to help the elimination of stones. If the stone is larger than 0.6 cm, surgical lithotripsy or extracorporeal shock wave lithotripsy is required.
