    Fig. 2. The Koch urethroscope. necessary for iutra-iirethral work —e. g., cotton carriers, canula to connect with a syringe, small knife, electrodes, etc. The technique for an examina- tion is as follows : The patient may be either in a sitting posi- tion or in a lithotomy position. For all ordinary work he may be on an examining table, on his back, with hips considerably ele- vated, and the legs spread apart. After using ordinary antiseptic precautions the instrument with maudrin is introduced. If it is desired to insert it into the pos- terior urethra, the suspensory ligament is made lax by placing the left hand on the pubic re- gion and making it give, so that the instrument held with the right hand passes almost without effort into and through the pos- terior urethra. There are but rare instances where any local ansesthetics are required. If so, with a Guyon capillary catheter, 1 to 2 c.c. of a 3 per cent, eucain or cocaine solution are sufficient to anaes- thetize the ])arts. All local ances- thefics change the appearance of the urethra, hence it is best to avoid their use. It is best to in- sert the largest tube that will enter the external urethral orifice.
