URINARY STONE CARE
Urinary Stones: Testing and Treatment
Sudden severe pain in the side or back can be caused by a urinary stone. We evaluate pain, infection risk, kidney function and the location and size of the stone.
Medically reviewed by Koshiro Nishimoto, MD, PhD (Urologist)When pain is severe
After examination and urinalysis, abdominal X-ray and non-contrast CT may be performed promptly when appropriate. Pain relief is provided in parallel, after checking kidney function, allergies, pregnancy possibility and gastrointestinal or cardiovascular risks.
What the tests tell us
- Urinalysis checks for blood and infection.
- CT shows the stone's location and size and can identify obstruction.
- X-ray is useful for selected stones and follow-up.
- Blood tests may assess inflammation and kidney function.
Treatment
Small stones often pass without surgery. Medication, hydration advice and follow-up imaging may be used. Infection with obstruction, impaired kidney function, uncontrollable pain or a stone unlikely to pass may require urgent referral or a procedure at an appropriate hospital.
Seek urgent help
High fever, confusion, inability to keep fluids down, very low urine output, pregnancy with severe pain, or pain that remains intolerable may require emergency care rather than waiting for normal clinic hours.
