Cystoscopy is an office procedure in which a small, flexible
telescope is used in a man to inspect the urethra and bladder. In a
woman, a small, rigid telescope is used. This inspection is done with
the aid of a fiber optic light source connected to the telescope.
Running water allows one a clear view down the telescope into the
bladder. The water gradually fills the bladder and smoothes out the
bladder walls, enabling a clear inspection of the inside of the bladder.
This procedure allows the doctor to detect causes of
urinary bleeding (whether microscopic or gross hematuria) from
problems such as tumors or obstruction from strictures, prostate
enlargement, stones, etc.
No special preparation is needed, and the procedure is
short and easily tolerated after numbing the urethra with topical
anesthetic jelly. Rarely, a patient may experience some burning or minor
bleeding after the procedure, but most will resume their normal daily
activities immediately after this investigation.
