The treatment of kidney stones is based on the size and number of stones, the shape and location of the stones, the composition of the stones, whether the stones are complicated by infection, whether the stones have caused obstruction, hydronephrosis? The treatment plan will be decided based on the size, number, shape and location of the stone, the composition of the stone, whether the stone has caused infection, whether the stone has caused obstruction, hydronephrosis, whether the stone has caused damage to the kidney parenchyma, how the kidney functions, and the patient’s general condition. When the stone is located in the small calyx or the lower calyx, and the neck of the calyx has a narrow capacity, it is difficult to be discharged even if the stone is discharged (more than 2mm). According to the literature, 90% of stones less than 4 mm can be discharged; 50% of stones less than 6 mm can be discharged; and only 20% of stones larger than 6 mm can be discharged. Extracorporeal shock wave lithotripsy is clinically known as ESWL, which uses extracorporeal shock wave to shatter the stones in the body after focusing, so that they can be excreted with urine to achieve the treatment purpose. The application of ESWL is undoubtedly an unprecedented change in the treatment of kidney stones. The treatment is safe, efficient, less painful and quick recovery, and combined with traditional Chinese medicine for stone removal, it can receive twice the effect with half the effort.
