It has been proved that due to the location of the stone in the ureter, the length of stay, the size of the stone and the degree of obstruction to the ureter, the response to various treatment methods is also different. Therefore, before treating stones, a careful medical history should be taken to understand the location, size, retention time and hydronephrosis of the stones to determine the treatment method. Since the 1980s, ESWL has been widely used in the treatment of ureteral stones. With the continuous maturation of ESWL technology and the widespread use of minimally invasive techniques such as ureteroscopic endolithotripsy in clinical practice, the treatment of ureteral stones is becoming more and more inclined to minimally invasive techniques and the proportion of open surgery is decreasing. What should we do for patients who have ureteral stones but have not caused obstructive effusion? The first thing we need to do is to perform a urographic urogram to determine the location of the ureteral stone, is it in the upper segment? middle segment? or lower? We can also see the size of the stone and whether there is hydronephrosis, etc. 1. For patients with lower ureteral stones without hydronephrosis, regardless of the size of the stones, we can first use lithotripsy granules, together with drugs to dilate the lower ureter, to try lithotripsy treatment. If the stone is discharged, the treatment is successful. If the stone is still in the original location of the lower segment and there is still no hydronephrosis, you can continue to take lithotripsy medication. If hydronephrosis starts to appear in the kidney, it means that the stone is difficult to be discharged and needs to be treated by ureteroscopy for lithotripsy. For patients with middle or upper ureteral stones without hydronephrosis, ESWL lithotripsy is effective and has a high crushing rate as long as the contrast agent can be passed around the stone during urography, which means the stone is small, has a short residence time and has no adhesion to the ureteral wall. If the stone has been crushed, the treatment should be changed to ureteroscopic lumpectomy to prevent severe ureteral fibrosis and serious adhesions. This is because ESWL has a damaging effect on the tissues, causing fibrous degeneration and inflammatory strictures. Of course, middle or upper ureteral stones can also be removed from the body using lithotripsy medications, as described above for lower ureteral stones. During the treatment process, all should drink a lot of water daily, with physical exercise and healthy diet to promote the stone out.
