Why Kidney Stones Can Happen During Pregnancy Pregnancy increases the risk because: Hormonal changes (especially progesterone) relax the urinary tract → urine flows more slowly. The growing uterus presses on the ureters. Increased calcium excretion in urine. Dehydration (common with nausea/vomiting). Symptoms Symptoms are similar to non-pregnant cases: Severe pain in the side or lower back (often one-sided) Pain that radiates to the lower abdomen or groin Nausea and vomiting Blood in urine Painful urination Urinary urgency Fever (this is urgent and requires immediate care) ⚠️ If there is fever, chills, or decreased baby movement, seek emergency care immediately. How It’s Diagnosed Because radiation should be avoided during pregnancy: Ultrasound is the first-line imaging test. MRI may be used if needed. CT scans are usually avoided unless absolutely necessary.
