What should you know about uric acid kidney stones?

A stone can irritate or block part of the urinary tract, causing severe flank or abdominal pain, painful urination, nausea, or blood in the urine. Dehydration can make urine more concentrated, while body chemistry, diet, and some medical conditions can influence uric acid levels. Symptoms can overlap with urinary infection, so pain alone does not confirm a stone.

A clinician may use urine and blood tests, review previous stones and medicines, and arrange imaging such as an abdominal ultrasound. Stone analysis, when a stone is collected, can help confirm its type. Management depends on the stone’s position, size, symptoms, kidney function, and whether urine flow is blocked.

Seek medical assessment for suspected renal colic rather than relying on home remedies. Follow the recommended pain plan and drink according to clinical advice; people with kidney, heart, or fluid-balance problems may need individual limits. A clinician may prescribe medicine to change urine chemistry or help a stone pass, and a larger or obstructing stone may need a procedure. For prevention, follow personalised advice on fluids, food, and treatment of conditions that raise uric acid.

Go to urgent care for flank pain with fever or chills, repeated vomiting, inability to pass urine, severe unrelenting pain, or feeling faint. A blocked infected urinary tract can become dangerous quickly. Seek review for new painful urination or abdominal pain, especially when symptoms are worsening or urine output changes.

Ask whether imaging is needed, whether the stone is obstructing urine, and how its type was determined. Discuss safe fluid goals, urine chemistry testing, medicines that alter uric acid, and what to do if pain or urinary symptoms return.
