Cystoscopy is a procedure that enables your doctor to view the inside of your bladder and urethra in great detail. This is done by using a specialized instrument called a cystoscope. This instrument has lenses like a telescope or microscope. Some cystoscopes use optical fibers that carry an image from the tip of the instrument to a viewing piece at the other end. The cystoscope is as thin as a pencil and has a light at the tip.
The test may be performed for a variety of reasons:
- Diagnose and evaluate urinary tract disorders
- Check for cancer of the bladder or urethra
- Diagnose an enlarged prostate
- Help find out the cause of pain
- Diagnose recurrent bladder infections
- Check for urinary blockage, unusual growth, stone in the urinary tract
- Need for a bladder catheter
- Loss of bladder control
- Blood in the urine
- Unusual cells found in urine sample
