If there is no infection, simple kidney stones can be treated by surgery, mainly by percutaneous nephrolithoscopy and ureteroscopy. If it is accompanied by some symptoms of infection, timely anti-inflammatory symptomatic treatment is needed, and at the same time, extracorporeal drainage by percutaneous nephrotomy can be performed to drain excessive fluid out of the body, so as to relieve the pressure in the kidney, and then choose a certain time to completely crush the stone and discharge it out of the body, and should keep enough water to prevent urinary system infection. If there is an inflammatory state, anti-inflammatory symptomatic treatment should be carried out before surgery, and the inflammatory infection should be completely controlled before the lithotripsy surgery, otherwise, more serious infection problems may occur after surgery.
