Extracorporeal Shock Wave Lithotripsy is a non-invasive treatment for stones that does not require incisions. The patient simply lies down on the lithotripter, locates the stone using X-rays or using ultrasound, and places the focal point of the extracorporeal shockwave lithotripsy instrument on the stone to begin shockwave lithotripsy. The process of lithotripsy is almost painless for the patient, there may be slight localized shock or localized mild pain, but the body will not experience any trauma or cuts, which is a preferred method of treating stones. For patients who have repeated extracorporeal shock wave lithotripsy treatments and there is no significant change in the size and location of the stones or there is aggravation of pain symptoms, aggravation of fluid in the kidneys, and progressive decline in renal function, it is necessary to carry out open surgery or use other minimally invasive to take out the stones at an early stage to restore the function of the kidneys if necessary. After extracorporeal shock wave lithotripsy, it is necessary to go to the hospital every week or so for review and observation of stone removal.
