Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
How to catch one: urinate through a sieve or filter during an episode - stones are often only millimetres across
-
Seek urgent help for stone symptoms with fever or inability to pass urine, whatever the stone type
-
Specialist: a consultant urologist usually leads assessment and treatment
-
What follows analysis: calcium oxalate prompts fluid, salt and oxalate advice; uric acid stones may dissolve with urine alkalinisation; infection stones need complete clearance; cystine stones need lifelong specialist care
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
Around 80% of stones are calcium-based (oxalate more often than phosphate), roughly 10% are uric acid, and the remainder include infection-related struvite and rare cystine stones. Composition cannot be reliably guessed from a scan, yet it changes management decisively: uric acid stones, for instance, are invisible on plain X-ray but can be dissolved without surgery by making the urine less acidic.
Diagnosis and treatment routes
Analysis uses infrared spectroscopy on even tiny fragments. A urologist pairs the result with blood tests and, in recurrent formers, 24-hour urine chemistry to build a personal prevention plan - and repeat analysis after a new stone matters too, because composition can change over time. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant urologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
