When a kidney stone is found to be about 1cm in diameter, it needs to be lithotripsy because the narrowest part of the ureter is about 4-5mm in diameter and a stone of about 1cm cannot be discharged by conservative treatment. If a kidney stone is located in the renal pelvis, extracorporeal shock wave lithotripsy can be used to crush the stone into two or three segments. If the calcium content of kidney stones is high and hard, extracorporeal shock wave lithotripsy is not easy to achieve the purpose of lithotripsy, Holmium laser lithotripsy such as ureteroscopic Holmium laser lithotripsy or percutaneous nephrolithotripsy Holmium laser lithotripsy should be chosen to completely crush the stones to cure the kidney stones. At the same time, patients should drink more water and urinate more often to prevent urinary tract infections from aggravating the progress of the disease.
