Thepenis is tunneled by means of a narrow bistoury or medium trocarand cannula, through the glans, above its groove, along the penis toa point beneath the hypospadiac opening, when it is made to emergeat one side of, but close to, the urethra; the tube of prepuce is drawnthrough the tunmel and sutured where it enters the glans and alsowhere it emerges (Fig. 8g6). At the end of ten days the pedicle of the flapis cut through close to the new meatus. The second operation, made at alater period, consists of a perineal opening into the urethra and insertion of.
