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 ]
A urologist inserts a scope into the urinary tract to locate the stone. The scope may be a cystoscope, ureteroscope, renoscope or nephroscope.An optical fiber is inserted through the working channel of the scope, and laser light is directly emitted to the stone.

The physician can then see the stone and remove it with a small basket at the end of a wire that is inserted through an extra tube in the ureteroscope. For larger stones, the physician may also use the extra tube in the ureteroscope to extend a flexible fiber that carries a laser beam to break the stone into smaller pieces that can then pass ...

Ureteroscopy has become increasingly popular as flexible and rigid fiberoptic ureteroscopes have become smaller. One ureteroscopic technique involves the placement of a ureteral stent (a small tube extending from the bladder, up the ureter and into the kidney) to provide immediate relief of an obstructed kidney.
In radiology and urology, a cystography (also known as cystogram) is a procedure used to visualise the urinary bladder.. Using a urinary catheter, radiocontrast is instilled in the bladder, and X-ray imaging is performed.
An intravenous pyelogram is used to look for problems relating to the urinary tract. [5] These may include blockages or narrowing, such as due to kidney stones, cancer (such as renal cell carcinoma or transitional cell carcinoma), enlarged prostate glands, and anatomical variations, [5] such as a medullary sponge kidney.
