Extracorporeal lithotripsy does not cause much damage to the kidney because it mainly uses extracorporeal shock waves to achieve the effect of breaking up the stones in the patient’s body. The damage to the kidney caused by extracorporeal lithotripsy is mainly caused by the damage to the small blood vessels of the kidney caused by the crushed stones during the lithotripsy process, which is mainly manifested as bleeding symptoms, but usually can be relieved by itself in 1-2 days. Overall, the damage is minor and the procedure can be performed without anesthesia while the patient is awake, avoiding the risks associated with anesthesia. Although a single extracorporeal lithotripsy is not too harmful to the patient’s kidneys and body, it can be damaging to the patient’s kidneys if the patient undergoes frequent extracorporeal lithotripsy within a short period of time. Therefore, doctors usually perform extracorporeal lithotripsy 1-2 weeks apart and not too many times. Patients are advised to drink more water after lithotripsy. Patients may experience pain during the process of lithotripsy discharge from the urethra and may take oral pain medication for pain relief if necessary.
