The invention belongs to the field of medical machinery, and particularly relates to a diagnosis and treat integral confocal cystoscope system which comprises a hard cystoscope, wherein a treatment unit is arranged at the end part of a hard endoscope of the hard cystoscope, and a host machine of a treatment system is connected onto the hard cystoscope and correspondingly matched with the treatment device for use. The diagnosis and treat integral confocal cystoscope system is organically combined with a laser scalpel system or a microwave scalpel system through the hard cystoscope and a confocal laser scanning microscope system. The clinical application of the diagnosis and treat integral confocal cystoscope system can realize the effect of simultaneous diagnosis and treatment, and also can solve the problems of two aspects of patient diagnosis and treatment, the endoscope is prevented from being frequently changed, a large amount of operation time is saved, the pain of a patient is relieved, furthermore, the operation accuracy and safety are improved, and an unexpected effect is obtained.
