Cystoscopy is a medical procedure that allows doctors to examine the inside of the bladder and urethra using a thin, flexible tube called a cystoscope. This instrument is equipped with a light and camera, enabling the physician to visualize any abnormalities, such as tumors or infections. The procedure is typically performed in a doctor's office or outpatient setting. It may be done under local or general anesthesia, depending on the patient's needs. Cystoscopy can also be used to collect tissue samples or remove small growths, aiding in the diagnosis and treatment of various urinary conditions.
