Patients with bladder stones, if the stones are less than 0.5 cm in size, can promote the natural expulsion of the stones by drinking more water and urinating frequently. If the stones are larger, over 0.5 cm in size, treatment may require extracorporeal shock wave lithotripsy or surgery. For patients undergoing extracorporeal shock wave lithotripsy, generally, if the stones are between 0.5-1.5 cm in size, this treatment can be performed. After the treatment, it is also necessary to drink more water and urinate frequently to facilitate the expulsion of the stones. For larger stones, over 1.5 cm, surgical treatment is required.
