Nephrolithiasis management in pregnancy: the initial option is which?

• A. Trial of passage with hydration and analgesia
• B. Immediate ureteroscopy with stent
• C. Shockwave lithotripsy
• D. Percutaneous nephrolithotomy

Answer: (A)

In pregnancy, the safest first approach to nephrolithiasis is conservative management aimed at allowing spontaneous passage while protecting both mother and fetus. Hydration helps promote urine flow without risking overload, and analgesia should be chosen with fetal safety in mind—acetaminophen is preferred, with NSAIDs avoided and opioids used only if necessary for short durations. Imaging and diagnostics are kept to non-ionizing methods when possible, with ultrasound used to assess obstruction rather than relying on CT or X-ray. Most small stones have a good chance of passing on their own, especially if located in the distal ureter. The goal is to observe and treat symptoms, reserving invasive interventions for signs of obstruction, infection, or persistent pain that requires relief. If obstruction or infection develops or the stone fails to pass, escalation to procedures like ureteral stenting or a percutaneous nephrostomy is considered to relieve blockage, with definitive stone removal planned in the second trimester or after delivery if needed. Therefore, starting with a trial of passage with hydration and analgesia is the best initial option.
