Cystoscopy
Overview
Cystoscopy is endoscopy
of the urinary bladder
via the urethra
. It is carried out with a cystoscope.
Diagnostic cystoscopy is usually carried out with local anaesthesia. General anaesthesia
is sometimes used for operative cystoscopic procedures.
The urethra
is the tube that carries urine
from the bladder to the outside of the body.
The cystoscope has lenses like a telescope
or microscope
. These lenses let the doctor focus on the inner surfaces of the urinary tract.
