Kidney stones are not prone to nephritis after surgery.1. Kidney stones are a common clinical condition and a frequent occurrence. Nowadays, kidney stone surgery is a minimally invasive procedure, which can be performed according to the size of the kidney stone and the degree of hydronephrosis, using percutaneous nephrolithoscopic ultrasonic lithotripsy to remove the stone, or transurethral ureteral soft microscopic holmium laser lithotripsy, etc. 2, while nephritis is a disease of the kidney itself, commonly known as glomerulonephritis, nephritis tends to be mostly an immune disease, which has nothing to do with kidney stone surgery. 3, some infected kidney stones, if the infection is not well controlled before surgery, there is a possibility of bacteraemia during and after surgery. If the infection is not well controlled before surgery, there is a possibility of bacteremia during and after surgery, especially urogenic sepsis, which is a systemic inflammatory reaction and has nothing to do with the local lesion of nephritis, which does not easily cause nephritis.
