Cystoscopy
Cystoscopy (cystouresthroscopy) is a diagnostic procedure of viewing a person's urinary passage and the urinary bladder, collecting urine samples and examining the prostrate gland through an instrument. The cystoscope is as thin as a pencil and has a light at the tip. Many cystoscopes have extra tubes to guide other instruments for procedures to treat urinary problems. Through a cystoscope, the urologist can focus on the inner surfaces of the urinary tract. Some cystoscopes use optical fibers that carry an image from the tip of the instrument to a viewing piece at the other end.
Ridid cystoscope: This is a solid straight telescope that is used along with a high intensity light source and a separate channel to allow other instruments to be attached.
Flexible cystoscope: This is used particularly for diagnosis and follow-up of most bladder tumors. It is a fibre optic instrument that can bend easily and has manoeuvarable tip that makes it easy to pass along the curves of the urethra.
Cystoscopy is also done to evaluate problems that cannot be seen on x ray. Cystoscopy is used to further investigate the problems detected by ultrasound or intravenous pyelography. In women, cystoscopy helps to reveal uterine prolapse. A common and temporary side effect of this test is swelling in the urethra. A urinary catheter may be left in the patient's bladder to help drain the urine until the swelling in the urethra subsides.
