Pregnant women who are clearly diagnosed with the presence of kidney stones are currently only able to relieve some of the symptoms caused by kidney stones through medication, such as kidney stones with obvious renal colic, injections of progesterone injection, scopolamine injection, methotrexate injection lasting 3-5 days can effectively relieve the pain, and these drugs will not have any effect on the fetus. It is also important to take some sensitive antibiotics by mouth, such as azithromycin tablets, cefuroxime tablets, amoxicillin capsules. As long as the inflammatory urinary tract infection is well controlled, kidney stones are less likely to cause pain. If the kidney stone causes more obvious water in the kidney, ureteral tube can be placed under local anesthesia to drain the water and protect the kidney function, and then the stone can be removed by lithotripsy after the baby is born.
