Cystoscopy :
Cystoscopy is a procedure in which a urologist examines the urethra and the bladder. The procedure involves the use of a cystoscope, which is a slim tube-like device with a light and a camera on its tip. The device is inserted into the body via the urinary opening. Besides examining the urinary tract from within, a cystoscope can be used to inject medication, remove bladder stones, treat urethral strictures and extract pieces of tissue for biopsy.
Before the procedure begins, the urologist will apply a numbing gel to the urethra so the patient does not feel any pain. Then, the cystoscope is inserted into the urethra. Next, some sterile salt water is injected into the urethra and bladder via the cystoscope to stretch them out. The urologist can then clearly see the insides of the bladder and urethra. If an unusual growth is found, then the doctor may insert additional instruments via the cystoscope and remove it.
