Post-traumatic or failed postoperative proximal urethral obliteration commonly is managed by technically demanding transpubic procedures. Five cases are reported, which were treated successfully by forceful retrograde perforation with a urethral sound guided by a finger inserted into the prostatic urethra. Temporary urethral catheterization followed by a program of daily self-dilation by catheter during maturation of the tract, with visual urethrotomy as required, facilitated healing.
