For ureteral stones less than 6 mm in diameter, the probability of self-discharge is about 60-80%, therefore, for the first occurrence of such ureteral stones, medication can be used for stone removal treatment for 1-2 months and then review ultrasound or imaging. According to the latest research, we can add some ureteral smooth muscle relaxing drugs, such as Cordova and Harle, which can help to remove the stones; drink more water and do more activities, such as skipping rope, if there is no combined renal colic and hematuria. If the stone is still not discharged, you can consider extracorporeal shock wave lithotripsy (one of the preferred methods for upper ureteral stones) or laser or pneumatic ballistic lithotripsy under ureteroscopy (the preferred treatment for middle and lower ureteral stones, because the overlap of middle and lower ureteral stones with the pelvis affects the effect of extracorporeal shock wave lithotripsy, so ureteroscopy is more effective). If the stone causes stubborn renal colic, which seriously affects life and the treatment effect is not good, ureteroscopic lithotripsy can also be used as soon as possible. For ureteral stones of 7-15 mm in diameter (upper segment stones can be treated by extracorporeal shock wave, but the larger the stone, the less effective shock wave lithotripsy is.) Ureteroscopic lithotripsy can be used for stones in the middle and lower segments. For embedded stones in the upper segment (often with a long duration of disease, such as staying in the same place for more than a month, often combined with moderate or severe hydronephrosis), the mucous membrane of the ureter around the stone is often repeatedly stimulated by the stone staying, resulting in the growth and wrapping of polyps around the stone, which affects the effect of shock wave lithotripsy, and such stones can also be lithotripsy by ureteroscopy. If intraoperative ureteral stones migrate up into the kidney, they can be further lithotripsy in the kidney in combination with extracorporeal shock wave lithotripsy. Percutaneous nephrolithotripsy is also a good option to deal with embedded stones in the upper ureter more thoroughly, basically removing the stones completely in one go. For stones in the middle and lower ureter with a diameter of 15 mm or more, ureteroscopy or open stone extraction can be used. For upper ureteral stones over 15 mm in diameter, percutaneous nephrolithotomy is a better minimally invasive option because these stones tend to exist for a longer period of time and are often combined with moderate to severe hydronephrosis in the kidneys.
