Kidney stones are usually larger than 2cm before they need to be operated for treatment. Treatment of kidney stones can be carried out through medication for stone removal, extracorporeal shock wave lithotripsy and surgery for different sizes of stones. Kidney stone is a disease caused by the crystallization of crystalline substances in urine, such as calcium, oxalate, urate, etc., which are precipitated from the urine and deposited in the kidneys. The disease can be treated by medication, extracorporeal shockwave lithotripsy and surgery, and generally, for stones over 2cm, it is necessary to treat them through percutaneous nephrolithotomy, ureteroscopy, lithotripsy and other surgical methods. Percutaneous nephrolithotomy and ureteroscopic lithotripsy are minimally invasive surgeries that cause less damage to the body, so there is no need to worry too much. In addition, stones smaller than 6mm can be removed by medication, while stones larger than 6mm and smaller than 2cm can be treated by extracorporeal shock wave lithotripsy. If you are diagnosed with kidney stones, please follow the doctor’s instructions for treatment.
