Urinary Stone Disease

Urinary stone disease is one of the most common urological problems treated at Changi General Hospital (CGH). They are usually formed in the kidneys and may get stuck in the ureter, blocking the flow of urine and causing pain. We offer a range of endourological and minimally invasive techniques to treat this common problem.

Treatments for urinary stones include Extracorporeal Shock Wave Lithotripsy (ESWL), Percutaneous Nephrolithotomy (PCNL) or laser lithotripsy (endoscopic laser surgery) performed through an endoscope. Virtually all stones in the urinary tract can be accessed and treated through the endoscopes, without any incision or with a small incision. For example, patients with large staghorn kidney stones can be treated with PCNL, using a small key-hole incision instead of conventional open surgery, which requires a long and painful incision.
