The preliminary results of an ultrasound study of the anatomy of the female urethra are presented. In this study an intraluminal probe was used and the results were compared with permicturitional transvaginal ultrasound data. Both morphometric and morphological results of the two methods coincided. The images obtained with the intraluminal ultrasound probe gave more information on the urethral mucosa, allowing a circular display of the mucous layer being examined.
