Doctors perform cystoscopy procedures by inserting a special scope into your urethra. This is the tube your urine comes out of. It's usually done in the doctor's office and it usually only takes 10 minutes. Your doctor will ask you to empty your bladder before numbing the area and inserting the cystoscope into it to find the source of any problems like blockages or bleeding. If they find anything suspicious, they can take a sample to look at under a microscope.
