An exemplary embodiment includes a probe tube at which an ultrasonic array is disposed. The aim of the disclosure is to construct an ultrasonic probe which, given an optimally small overall diameter, can particularly be employed for bladder endoscopy of male patients. The aim is inventively achieved in that an optical insert and an ultrasonic array are disposed in two layers radially offset and also offset relative to one another in the longitudinal direction of the tube, being disposed in such manner that the end face of the optical insert opening in front of the ultrasonic array in the direction toward the distal tube end only projects over the application surface (ultrasonic elements) of the ultrasonic array to such degree that, on the one hand, the space above the ultrasonic array can be sufficiently illuminated and, on the other hand, given a largely complete filling of the tube space below the ultrasonic array and optical insert with a bundle of the electrical connecting lines of the ultrasonic array proceeding in the direction of the proximal tube end, the overall diameter of the probe tube with an inserted or emplaced optical insert is optimally low for endoscopy purposes.
