Ureteroscopy is an 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 ]
The stent is removed by cystoscopy, an outpatient procedure. Cystoscopy involves placement of a small flexible tube through the urethra (the hole where urine exits the body). The procedure, which usually takes only a few minutes and causes little discomfort, is performed in an outpatient clinic or ambulatory surgery centre.
The procedure is more painful for men than for women due to the length and narrow diameter of the male urethra, and results of a 2019 systematic review of the literature found that intraurethral lidocaine greatly reduces this painful procedure in men. [5] Relaxing the pelvic muscles helps make this part of the test easier.
Ho:YAG lasers have wavelength of 2100 nm (infrared) and are used for medical procedures in urology and other areas. They have qualities of CO 2 and Nd:Yag lasers, with ablative and coagulation effects. [10] Holmium laser use results in smaller fragments than 320 or 365 micron pulsed dye lasers or electrohydraulic and mechanical methods. [11]
Pyelogram (or pyelography or urography) is a form of imaging of the renal pelvis and ureter. [1]Types include: Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system.

A procedure called a ureteroscopy is also used to inspect the ureters. During this procedure a thin, lighted tube equipped with a camera is inserted through the urethra and into the bladder, ureter, and renal pelvis. This can also include a biopsy (small sample of tissues collected), which will then be inspected in the laboratory.
The first to examine the ureter through an internal approach, called ureteroscopy, rather than surgery was Hampton Young in 1929. [30] This was improved on by VF Marshall who is the first published use of a flexible endoscope based on fiber optics, which occurred in 1964. [30]
