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. Some cystoscopes use optical fibres (flexible glass fibres) that carry an image from the tip of the instrument to a viewing piece at the other end. Cystoscopes range from between the thickness of a pencil, up to approximately 9mm and have a light at the tip. Many cystoscopes have extra tubes to guide other instruments for surgical procedures to treat urinary problems.
There are two main types of cystoscopy - flexible and rigid - differing in the flexibility of the cystoscope. Flexible cystoscopy is carried out without the use of local anaesthesia on both sexes. Typically, xylocaine gel (such as the brand name Instillagel) is used as an anaesthetic, instilled in the urethra. Rigid cystoscopy can be performed under the same conditions, but is generally carried out under general anaesthesia, particularly in male subjects, due to the pain caused by the probe.
A doctor may recommend cystoscopy for any of the following conditions:

I was suffering from a severe headache and even the potent pain killers only gave me slide relief. I went for a CT Scan plus MRI and doctors found a ‘blood clot’ in the brain. Neurosurgery was suggested and had a stroke while going through angiogram. My life was miserable until Dr Itua herbal made medicine was introduced to me. I took Dr Itua Herbal Made Capsule Plus 3 times daily and within 20 days I saw big relief from the pain and within a few weeks I was able to walk and gain back my mobility. The following MRI confirmed the ‘blood clot’ had disappeared and the doctors were very surprised and said it was a ‘miracle’. Now, I am doing Cardio 2 times a week.You can contact Dr Itua herbal center on drituaherbalcenter@gmail.com his herbal made also cure Herpes Virus,HPV,ALS,MS,Hepatitis,Diabetes,HIV,Cancer,Parkinson and so many other diseases humans can have.
