PROBLEM TO BE SOLVED: To provide a method for sensitively diagnosing lower urinary tract disorders, particularly interstitial cystitis, to visually, simply, and clearly determine bladder ulcer without requiring bladder hydrodistention under anesthesia. SOLUTION: In this method, lower urinary tract disorders are diagnosed by observing a blood vessel and/or a newly formed blood vessel in the surface of bladder mucous membrane by using a bladder endoscope system having a special light observation device. In addition, in this method, the observation of the blood vessel and/or the newly formed blood vessel includes the observation of an abnormality of the blood vessel and/or the newly formed blood vessels in the surface of the bladder mucous membrane out of the abnormalities of blood vessels and/or newly formed blood vessels by visually comparing an image of the surface of the bladder mucous membrane and an image of a deep portion of the bladder mucous membrane acquired by using a bladder endoscope system having a narrow band imaging (NBI) device.
