If there are stones in both the kidney and the ureter, then it is recommended to go to the hospital for examination and evaluation, and even hospitalization for surgical treatment if necessary. In principle, the ureteral stones should be treated first. The ureteral stones will directly lead to the obstruction of the ureter, which will produce the symptoms of hydrocele and low back pain, and if the ureteral stones are not discharged, the kidney stones will not be easily discharged. Even in the process of treatment, the stone is completely involved in the formation of stone steps within the ureter, which is often difficult to deal with, so you need to know the size and location of kidney stones and ureteral stones to decide how to treat. If the stone in the kidney is relatively small <1cm and the stone in the ureter is also <1cm, it is recommended to choose extracorporeal shock wave lithotripsy to crush the stone in the ureter first and then deal with the stone in the kidney. However, if the ureteral stone is >1cm and the kidney stone is >2cm, the effect of extracorporeal shock wave lithotripsy is often poorer, and it is recommended that the patient be hospitalized for Holmium ureteroscopy and minimally invasive laser surgery.
