The lesion principle of kidney stones caused by gout is mainly stones produced by the continuous accumulation of uric acid salts in the kidney. If the stones are small in diameter, conservative stone removal treatment can be chosen. Patients can take oral citrate combination, including potassium citrate and sodium citrate, which can regulate the pH of urine and facilitate the dissolution of uric acid stones. At the same time, oral ureteral dilation medications, such as methotrexate tablets and flavonol permethrin tablets, can dilate the ureteral duct diameter and facilitate the smooth discharge of stones. If the stones are large in diameter, the patient can first undergo extracorporeal shock wave lithotripsy to crush the stones into multiple segments and then undergo conservative stone removal treatment. If the stone is blocked in the ureter for a long time and cannot be moved, it may cause obstruction or encapsulated stone, which can be removed and restored to normal by Holmium laser lithotripsy.
