What should you know about asymptomatic kidney stones?

They may appear unexpectedly on an ultrasound or another scan performed for an unrelated reason. Some remain quiet, while others move, grow, or interfere with urine flow, so the next step depends on the scan and your health context.

A report may describe where a stone sits, its size, whether there are several stones, and whether the kidney’s drainage system looks widened. Location and signs of obstruction help a clinician judge whether observation or specialist assessment is more suitable.

Having no symptoms means the stone is not currently producing a noticeable stone episode. It does not show what the stone is made of, and it does not rule out later movement into the ureter, the narrow tube carrying urine to the bladder.

Review the scan report with a GP or the clinician who ordered it. Ask whether the kidney is draining normally, whether follow-up imaging is appropriate, and whether your medical history suggests urine or blood testing. Previous stones, urinary infections, kidney problems, and medicines can affect the plan.

Drink regularly enough that your urine is usually pale unless a clinician has restricted your fluid intake for another condition. Avoid forcing excessive fluid. General prevention advice may include moderating salt and keeping a balanced diet, while tailored advice depends on stone composition or test results.

Arrange prompt assessment for new pain in the side or back, abdominal pain, painful urination, visible blood in the urine, or difficulty passing urine. These changes can occur if a stone moves or disrupts urine flow.

Seek urgent care for fever or chills with side pain, inability to pass urine, persistent vomiting, faintness, or severe pain that is not settling. Infection behind a blockage and impaired drainage require timely evaluation.

Useful questions include where the stone is located, whether the scan shows obstruction, and what would make referral advisable. Confirm whether another image is planned, how you will receive the result, and whether your diet or medicines should change before more information is available.
