CT voiding urethrography and virtual urethroscopy: preliminary study with 16-MDCT.
OBJECTIVE
The purpose of this study was to demonstrate CT voiding urethrography and CT virtual urethroscopy. Fourteen CT voiding urethrography examinations on 13 men (mean age, 30 years) were prospectively performed with 16-MDCT. The clinical diagnoses of those patients included urethral injury, urethral stricture, and hypospadia. The CT voiding urethrogram was obtained with transverse CT of the voiding, contrast-filled urethra and display of 2D multiplanar and 3D virtual images.


CONCLUSIONS
The full urethral structure was clearly shown by CT voiding urethrography and virtual urethroscopy in all patients. The results of CT voiding urethrography and conventional methods correlated closely with the urethral diseases being imaged.
