Traditional kidney stones require a kidney incision to remove the stones, which is a very traumatic operation, painful and slow recovery for the patient. Later, the percutaneous nephrolithotomy technique emerged, which involves making a hole in the lumbar region and using a special device to break up the stone. However, because of the need for a hole in the kidney at the waist, the main risks of the procedure are severe bleeding and infection, and a few patients may have more serious complications. Nowadays, the Holmium laser lithotripsy technique of ureteral chondroscopy uses the natural lumen of the human urinary system without making any incision in the body and uses a fine mirror of about 3mm in diameter to break up and remove the kidney stones. It is a purely minimally invasive urological lumpectomy procedure. Holmium laser lithotripsy with ureteroscope has the advantages of lower surgical risk, less complications, less patient pain and faster recovery than percutaneous nephrolithotomy and traditional nephrolithotomy. Usually, patients can eat and move around 6 hours after the surgery, and can be discharged from the hospital 1-2 days after the surgery.
