There are two types of cystoscopes used to carry out the procedure, a rigid type and a flexible type. Both types are used for the same purposes and differ only in their method of insertion. The rigid type requires that the patient adopt the lithotomy...
position, meaning that the patient lies on his or her back with knees up and apart. The flexible cystoscope does not require the lithotomy position.
A cystoscopy typically lasts from 10–40 minutes. The patient is asked to urinate before surgery and advised that relaxing pelvic muscles will help make this part of the procedure easier. A well-lubricated flexible or rigid cystoscope (urethroscope) is passed through the urethra into the bladder where a urine sample is taken. There may be some discomfort as the instrument is inserted. Fluid is then injected to inflate the bladder and allow the urologist to examine the entire bladder wall. The cystoscope uses a lighted tip for guidance and enables biopsies to be taken or small stones to be removed through a hollow channel in the cystoscope.
During a cystoscopy, the urologist may remove bladder stones or kidney stones, gather tissue samples, and perform x-ray studies. To remove stones, an instrument that looks like a tiny basket or grasper is inserted through the cystoscope so that small stones can be extracted through the scope's channel. For a biopsy, special forceps are inserted through the cystoscope to pinch off a tissue sample. Alternatively, a small brush-like instrument may be inserted to scrape off some tissue. To perform x-ray studies such as a retrograde pyelogram, a dye is injected into the ureter by way of a catheter passed through the cystoscope. After completion of all required tests, the cystoscope is removed.

The 2D animation explains the process involved in a male cystoscopy procedure. A cystoscopy is a procedure that allows a urologist to see inside the urinary bladder. Note that the instruments shown in the animation are smaller relative to the patient in an actual cystoscopy.

Other Information
Endoscopy of the urinary bladder via the urethra is called cystoscopy. Diagnostic cystoscopy is usually carried out with local anaesthesia. General anaesthesia is sometimes used for operative cystoscopic procedures.
When a patient has a urinary problem, the doctor may use a cystoscope to see the inside of the bladder and urethra.
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. The cystoscope is as thick as a pencil and has 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 using local anaesthesia on both sexes. Typically, lidocaine 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.

In 2000, the estimated number of doctor visits and outpatient hospital visits by patients aged 20 or older with UTI or cystitis listed as a diagnosis was of 8.27 million visits (1.41 million men; 6.86 million women) with UTI as the primary diagnosis.
