In general, extracorporeal lithotripsy usually requires 2-3 shots. This treatment measure is a commonly used lithotripsy treatment option in urology. After locating the stones through ultrasound, high-energy shock waves are used to crush the larger urinary stones into smaller ones, which facilitates the expulsion of the stones. After the treatment, patients are required to drink more water to increase the amount of urine and try to expel the small stones. At the same time do some jumping movements, also conducive to the discharge of stones. In general, about one week after the treatment to review the urinary ultrasound, if the stone crushing effect is not satisfactory, you can consider 2-3 times of lithotripsy treatment. After 3 times of treatment, basically will not take this treatment again. For patients with recalcitrant urinary stones, other surgical methods should be considered, such as: cystoscopy lithotripsy lithotripsy, ureteroscopy lithotripsy lithotripsy, percutaneous nephrolithotripsy lithotripsy, and so on. Patients should not be too nervous, after diagnosis of the condition, follow the doctor’s instructions to carry out appropriate treatment, the stone will be emptied.
