Overview A flexible cystoscopy is where our physicians look inside a man's bladder and this can be viewed on a television screen. This is done through a flexible scope that is no larger than a catheter. Very little discomfort is associated with this procedure. Some of the reasons for having this procedure are: blood in the urine, bladder tumors, prostate enlargement, obstruction, chronic infections, bladder stones, and urinary leakage and difficulty urinating. The urethra is medicated with an anesthetic jelly prior to the procedure. An antibiotic is given afterwards to prevent infection. This is done as a precaution since all our instruments are sterilized just before the procedure.
