Urinary stones

Patients with urinary tract stones commonly present with renal colic, haematuria (bloody urine), urinary tract infections, hypertension or renal impairment. They may be found incidentally during investiga tions for other symptoms.

Asymptomatic  renal stones >5mm or any symptomatic stones need to be treated. Stones can be cleared with different treatment modalities depending on its size, location and patient factors. We offer external shock wave lithotripsy (ESWL), endoscopic holmium lasertripsy and percutaneous nephrolithotomy (PCNL) treatments. We will assess your stones with CT scans and x- rays to  advise on the most appropriate option to treat your stones. Most stones can be cleared with minimally invasive day procedures. Blood tests and dietary review are undertaken to reduce risk of future stone recurrence.

Ureteroscopes: These are 'telescopes' used to visualise stones within the urinary tract. Fine optical fibers are passed into these instruments to deliver holmium energy source to fragment and clear stones.

External Shockwave Lithotripsy (ESWL): Stones < 1.5cm within the kidney and upper ureter are suitable for ESWL treatment. The stone is located by an ultrasound image and fragmented non invasively with an energy source focused on the stone
