The treatment of ureteral stones in pregnant women needs to be considered according to the time of pregnancy and the condition of ureteral stones. 1.If the stone is very small and does not cause hydronephrosis and does not require surgical intervention, then let nature take its course and wait for the birth of the child before dealing with it as appropriate. In case of severe pain, you can give fluids and use antispasmodic drugs such as scopolamine and nifedipine. 2. If the stone is large and causes hydronephrosis, the following choices can be made according to the different stages of pregnancy: if the pregnancy is close to the late stage of labor, the stone can be treated as early as possible after the birth of the child, and the treatment methods are extracorporeal shock wave, ureteroscopy or open surgery; if the pregnancy is in the middle stage, as the fetus is not easy to abort, the stone can be treated according to the location of the stone with less influence on the fetus, and if necessary If the pregnancy is in the early stage (first 3 months), priority should be given to the treatment of stones to save the kidney, but the pregnancy can be terminated if necessary because the fetus is easily disturbed and aborted in the early stage of pregnancy.
