title: [On a modification of the otis urethrotome (author's transl)].
abstract: A modification of the Otis urethrotome is presented and the technique of internal urethrotomy with this instrument is described. The instrument opens parallel, and the incision blade makes a cut in two directions possible. Special additional parts at the top of the instrument make the introduction easier. The unintentional stretching of the urethra by the extraction of a conical instrument is therefore avoided.
