For a kidney stone that is less than 5 mm, what is the typical outcome?

• A. Pass spontaneously
• B. Invasive procedure
• C. Intravenous fluids
• D. Diet changes

Answer: (A)

Small kidney stones under five millimeters are likely to pass spontaneously through the urinary tract. Their small size lets them travel down the ureter and be excreted in urine, with many passing within a few weeks. The typical plan is conservative: keep well hydrated, manage pain, and sometimes use medical expulsive therapy to help the stone move along. Invasive procedures are reserved for stones that are larger, cause persistent blockage, or complications. IV fluids are supportive but don’t by themselves determine the outcome, and diet changes are mainly for prevention of future stones rather than the immediate passage. So, spontaneous passage is the expected outcome for a stone this small.
