A urinary stone forms when minerals crystallize in the kidney and can travel into the ureter, where it may lodge and block the flow of urine — causing some of the most severe pain in medicine.

Stones are common and tend to recur. Understanding the cause and confirming the stone's size and position are the first steps toward the right treatment and toward preventing the next one.
If several of these apply to you, a urological evaluation is worthwhile. This checklist is a guide, not a diagnosis.
We confirm the typical colic pattern and check for red flags such as fever.
Detects stones and any back-pressure on the kidney without radiation.
Locates and sizes radio-opaque stones to plan treatment.
Confirms blood and screens for infection that would change the plan.
Small stones often pass with hydration, pain relief and medication to relax the ureter.
Larger or obstructing stones are treated with shock-wave lithotripsy or endoscopic surgery — see the stone-treatment page.
A stone with fever is urgent; our 24-hour stone service handles acute episodes without a long wait.
Once clear, we review fluids and diet to reduce the chance of recurrence.
Stones are diagnosed with same-visit imaging and, crucially, backed by a 24-hour, 365-day emergency service — so acute stone pain is met promptly rather than after a long wait. English-speaking support and English records help if care spans more than one visit.
Urinary stone emergencies are seen 24 hours a day, 365 days a year — call the dedicated hotline.
Many small stones do, with fluids and pain relief. Larger or obstructing stones usually need a procedure — imaging tells us which.
A dedicated 24-hour, 365-day stone hotline (010-3830-1725) means acute stone pain is covered around the clock, not just during office hours.
Yes — fever with a blocked stone signals infection and needs urgent treatment. Seek care immediately.
Yes — ultrasound, X-ray and urinalysis are same-visit, so you leave knowing the stone's size, location and the plan.
