Ureteroscopy

The examination may be performed with either a flexible, semi-rigid or rigid device while the patient is under anesthesia. In specific cases, the patient is free to go home after the examination.

In pyeloscopy, the endoscope is designed to reach all the way to the renal pelvis (also called pyelum), thereby allowing visualisation of the entire drainage system of the kidney. The endoscope can contain an instrument port which allows for introduction of laser fibres to fragment stones, and micro-baskets to retrieve stone fragments. Kidney stones up to 2 cm in size can be treated by pyeloscopy.
