If kidney stones are found during pregnancy, they can usually be treated by the following methods: 1. If the kidney stones do not cause any clinical symptoms, they usually do not need to be treated and can be reviewed and observed regularly. 2. If the kidney stones irritate the mucous membrane of the urinary tract and cause painful symptoms, they can be treated with antispasmodic and analgesic drugs, and the more commonly used antispasmodic and analgesic drug is progesterone. Progesterone can significantly relieve the symptoms of pain caused by stones.3. If kidney stones cause urinary tract obstruction and hydronephrosis, the ureter and double J tube can be left in place to drain urine, reduce hydronephrosis and relieve the symptoms of obstruction. Surgery is not recommended for kidney stones during pregnancy, and if surgery is performed, it usually has a greater impact on the fetus, so patients during pregnancy usually use conservative treatment methods.
