Structurally， a stone in the body doesn't lead to fetal deformity. However， complications that result due to a stone can affect the fetus. For example， if a pregnant woman has a urinary tract infection caused by a kidney stone， the bacteria infecting the urinary tract may find their way to the developing baby in the uterus.
Moreover， kidney stones can cause pain and discomfort in the mother， which can stress the fetus. If the mother is experiencing severe pain or if the kidney stone causes any blockages in the urinary tract， then it may affect the overall health of the fetus.
In addition， the medications often used to manage kidney stones pose some risks to the fetus. Many drugs used to relieve symptoms of kidney stones are not recommended during pregnancy. For instance， ibuprofen can be harmful to the developing fetus， and some antibiotics may cause birth defects.
In conclusion， while kidney stones can't cause fetal deformities， they can present a risk to the health of the mother， and thus， the developing fetus. Any pregnant woman experiencing kidney stones should seek appropriate medical care to mitigate the risks and ensure a safe and healthy pregnancy.
