MeSH D018666

A ureteroscopy is a medical examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1] The procedure is useful in the diagnosis and treatment of disorders such as kidney stones and urothelial carcinoma of the upper urinary tract. [1] Smaller stones in the bladder or lower ureter can be removed in one piece, while bigger ones are usually broken before removal during a ureteroscopy.[ citation needed ]

The examination may be performed with either a flexible, semi-rigid, or rigid device while the patient is under anesthesia. [1] In specific cases, the patient is free to go home after the examination. [2]

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. [3] The endoscope can contain an instrument port which allows for introduction of laser fibres to fragment stones, and micro-baskets to retrieve stone fragments. [3] Kidney stones up to 2 cm in size can be treated by pyeloscopy. [3]
