A cystoscopy is an examination of the inside of the bladder (the baglike organ that stores urine in the body) using a thin, flexible, tube-like telescope called a cystoscope. This instrument is carefully passed up the urethra (the tube that carries urine out of the body) and into the bladder. A cystoscopy is useful for finding out what is causing your symptoms, or as a check-up for certain bladder conditions. During the procedure, the doctor may take a biopsy - a sample of the lining of the bladder - for examination in the laboratory.
Cystoscopy is routinely performed as an outpatient or day case, requiring no overnight stay in hospital. A general anaesthetic is rarely required, although a local anaesthetic jelly is usually applied to the area. In some cases, a sedative injection may be given.
