If there are many stones in the kidney, it is recommended to go to the hospital for examination and evaluation, and then treat them as follows: 1) Extracorporeal shock wave lithotripsy, which is suitable for kidney stones <2cm or less, can be chosen first, and then dynamically review the stone discharge, drink more water and urinate more after lithotripsy, or assist in lithotripsy medication for dynamic observation. 2) Surgery, which can be done by ureteroscopy Holmium laser lithotripsy, or percutaneous nephrolithoscopy Holmium laser lithotripsy. However, in the case of more stones and more widely distributed stones, multiple operations are needed to complete the treatment. Patients with hyperparathyroidism can cause multiple stones, or patients with congenital malformations of the urinary system can develop secondary kidney stones. In this case, the primary cause needs to be treated, such as parathyroidectomy, or related surgical treatment for urinary malformations, in order to prevent the recurrence of stones.
