How is the procedure performed?

Ureteric calculusThis is normally performed under general or spinal anaesthetic. The bladder is examined first and a guidewire inserted into the ureteric opening, past the stone, up to the kidney (pictured right); correct positioning is confirmed by "on-table" X-ray.

A long, rigid or flexible instrument is then passed alongside the guidewire until the stone can be seen. The stone is broken with a laser fibre or ultrasound probe and the fragments extracted with fine forceps or using a special retrieval "basket".

A ureteric stent may be inserted at the end of the procedure, depending on what has actually been done.
