flexible ureterorenoscopy (FURS) and laser

Q | the FURS procedure

A | FURS is carried out under a general anaesthetic. The first step is to examine the bladder with a telescope and to pass a guidewire and plastic tube up into the ureter (the pipe with connects the kidney to the bladder).

FURS XRayX-ray contrast (dye) fluid is injected up the tube in your ureter. This outlines the kidney system on X-ray and acts as a “roadmap for the FURS procedure (see X-ray picture). A small dilating sheath is passed over the guidewire into the ureter and the FURS telescope is then advanced up through the sheath into the kidney. The surgeon can manoeuvre the end of the FURS scope into all parts of the inner kidney using a hand control outside the body to flex the end of the scope as necessary. When the stone is seen, using a video transmitted image to a computer screen, it can be shattered using the laser fibre and power source. Once fragmented, the pieces can be removed using a tiny wire basket, which is passed up through the FURS scope.
