The 'bare area' of the male urethra. A new anatomical concept.

Clinical correlations have been made with the applied anatomy of the infradiphragmatic urethra. The entire urethra was removed en bloc and the infradiaphragmatic urethra was carefully dissected with metallic sounds in situ. The urethra immediately distal to the urogenital diaphragm is devoid of any corporal tissue anteriorly and constitutes the 'bare area' tha can easily be injured during rigid urethral instrumentation.
