Cytoscopy. This surgical procedure, known as a cytoscopy, is used to look at the health of a patient's bladder. Here, the patient's urethra (the duct through which urination occurs) is being dilated before an endoscope probe (cystoscope) is passed through it and into the bladder. The cystoscope usually has a camera at the end, which allows the surgeon to identify any problems with the bladder and, if necessary, take a biopsy (a sample of tissue) for further investigation.
