External Urethrotomy for Stricture Permeable Only by a Fili-form.—This operation has been greatly simplified by the use of a perinealstaff devised by me; it may be employed wdth either a whip or a Avhale-bone filiform bougie. It will be seen from the illustration (Fig. 296) thatthe instrument consists of two blades in close approximation, which, to-gether, form a smooth staff having a thumb-screw at one end, by mean^.

It works on the sameprinciple as the Otis dilating urethrotome. The distal end of the staffterminates in a rounded nut, which can be removed and replaced by awhip filiform, as shown in Fig. 296. An opening in the nut at the endof the staff will be observed, which leads into a tunnel through which anordinary whalebone filiform can be passed. The filiform is employedwhen it is found impossible to insinuate the whip bougie. When the whip bougie can be passed through the stricture, it isfastened to the perineal staff in the manner shown in Fig. 296. Theblades of the instrument are closed and the staff is passed into theurethra until arrested by coming into contact with the shoulder ofthe stricture. The whip bougie being pushed in front of the staff,reaches the bladder and curls up, and when th
