Cystourethroscopy is a medical procedure that allows healthcare professionals to visualize the interior of the bladder and urethra. This is achieved by inserting a cystoscope, which can be either rigid or flexible, through the urethra into the bladder. The procedure is particularly important for diagnosing and treating bladder tumors. During cystourethroscopy, the bladder may be filled with sterile saline to enhance the visibility of the bladder wall, facilitating the identification of any abnormalities, including tumors. Once the tumors are located, they can be treated using various methods, including fulguration, which involves the application of a high-frequency electrical current to destroy the tumors. Alternative methods such as cryosurgery or laser surgery may also be employed to achieve the same goal. The procedure is designed to address small bladder tumors, specifically those measuring between 0.5 cm and 2.0 cm in greatest diameter. Following the destruction of the tumors, the bladder is re-inspected to confirm that all targeted lesions have been adequately treated before the cystoscope is removed. This procedure is essential for managing bladder tumors effectively and is categorized under specific CPT® codes based on the size of the tumors being treated.
