Lithotripsy is divided into extracorporeal lithotripsy, percutaneous nephrolithotripsy and transurethral ureteral lithotripsy. Extracorporeal lithotripsy takes about half an hour, while the others generally take less than two hours. 1. Extracorporeal lithotripsy: Extracorporeal lithotripsy is to produce shock waves through the lithotripter, releasing energy to break down the stones in the body, and then discharged out of the body along with urine. It is suitable for the patients who have no other organic diseases and have smaller and fewer stones, and the time of lithotripsy is usually about 30 minutes, and it can promote the discharging of stones by drinking more water and standing on tiptoe. 2. Percutaneous nephrolithotripsy: It is to establish a channel in the patient’s waist, penetrate the nephrolithoscope into the renal pelvis and calyx, and carry out in vivo lithotripsy and stone removal. It is suitable for patients with complicated kidney stones and calculus, and usually adopts general anesthesia, and lithotripsy surgery takes about 1~2 hours. 3. Transurethral ureteral lithotripsy: the ureteroscope will be passed through the urethra and bladder to reach the ureter, and lithotripsy and stone extraction will be carried out under the action of endoscope, which is more suitable for patients with bladder stones and ureteral stones, and the time will be about 1 hour, and it will be relatively prolonged if the number of stones is larger or obstruction occurs. The time of lithotripsy is closely related to the size of stones and the way of surgery.
