A flexible direct vision fiberoptical viewing cable is placed within a urinary catheter with its tip located at a distal end of the catheter such that the surfaces of the distal end of both the viewing cable and the catheter are aligned so as to fit together in such a way as to form a composite smoothly curved surface to facilitate negotiating obstructions. The cable is maintained in this position within the catheter with the surfaces that comprise the tip of the instrument, maintained in alignment. The urethra is then viewed therethrough during all or part of the insertion procedure for observing and identifying obstructions that may be present and thereafter the fiberoptic cable is withdrawn while allowing the catheter to remain in place within the urethra.
