Prior to a cystoscopy, the patient needs to inform the urologist of any medicine allergies as well as follow the pre-procedural instructions, advises WebMD. These instructions include a period of fasting so that there are no fluids in the bladder during the procedure. The patient then takes medication to prevent the contraction of an infection during the cystoscopy. Finally, the patient is given a sedative to aid in relaxation and an anesthetic.

A doctor performs a cystoscopy to see inside the bladder and evaluate problems, WebMD explains. For instance, patients who experience urinary problems or frequent urinary tract infections can undergo a cystoscopy so that the doctor can look for the source of those issues. Doctors can also treat issues such as bleeding and kidney stone blockages during a cystoscopy by inserting tiny tools into the hollow tube of the cystoscope. Biopsies can also be performed as well as the removal of tumors and foreign objects.
