Kidney stones in pregnant women can be treated with antispasmodic drugs such as atropine, as well as ultrasound extracorporeal lithotripsy, or even surgical procedures. The treatment of kidney stones in pregnant women is a little more difficult than the usual kidney stones because the safety of both the pregnant woman and the fetus must be taken into account. If the kidney stones are relatively small, below 5mm, you can try to apply the antispasmodic drug atropine and instruct the patient to drink more water, more than 2000ml per day, so that a small portion of the kidney stones can be discharged. If the stone is larger than 5mm and the above methods are not effective, you should consider ultrasonic extracorporeal shock wave lithotripsy, which is relatively safe and non-invasive. If both of these treatments are less effective, surgical treatment should be considered. However, during surgical treatment, fetal heart monitoring must be strengthened to prevent preterm delivery. If the patient’s general condition is poor and surgical treatment is temporarily impossible, a DJ tube can be placed, which can temporarily relieve the symptoms of hydronephrosis.
