Minimally invasive surgery is not recommended for pregnant women with kidney stones because of the risk of miscarriage. Conservative treatment is recommended, and surgery for kidney stones should be considered after the end of labor. 1. Conservative treatment: If there are a small number of kidney stones during pregnancy, you can drink plenty of water, urinate regularly, and exercise appropriately to promote the expulsion of the stones. 2. Surgical treatment: Try to choose minimally invasive surgical treatment of kidney stones after delivery, which will not affect the fetus; if severe pain or even miscarriage caused by kidney stones occurs during pregnancy, you should consider ending the pregnancy as soon as possible, and focus on the treatment of kidney stones, so as to avoid life-threatening acute renal failure. Pregnant women are advised to actively cooperate with doctors for treatment, not to blindly use medication on their own, and to end the pregnancy if necessary.
