The treatment of stones depends on their size, location, and type. Small stones may pass on their own with increased fluid intake and pain management. Larger stones might require medical intervention. Extracorporeal shock wave lithotripsy (ESWL) uses shock waves to break up the stone. Ureteroscopy involves inserting a thin tube to remove or break up the stone. In some cases, surgical removal may be necessary. Diet modifications can also help prevent future stones. ????
