Kidney stones usually do not directly affect conception, but pregnancy may have some adverse effects on the pregnant woman and the fetus. Kidney stones are mainly caused by metabolic abnormalities, urological conditions, climate, diet, medications, etc. Symptoms include lower back pain, hematuria, urinary tract infections, and discharge of fine stones. Kidney stones usually do not involve the reproductive organs, which will not affect the production and transportation of sperm and eggs, so they usually do not affect conception. If you are pregnant and have kidney stones, you may experience some adverse effects on yourself and your fetus when you are examined and treated. For example, X-ray and CT examination, pain relief and anti-inflammatory drugs, and lithotripsy surgery may affect the pregnant woman and the fetus, so the patient should choose carefully and weigh the pros and cons. If the patient is not pregnant, she should treat the kidney stone before preparing for pregnancy; if she is already pregnant, she should go to a regular hospital in time, and under the guidance of the doctor, try to minimize the adverse effects of the treatment.
