The catheter must be introduced slowly and with the utmost gentleness, eye upward, until urine flows, showing that the bladder has been reached. The bladder is now emptied through the catheter and then the latter is withdrawn a full inch, so that its eye may lie just behind the membranous urethra. Now from the irrigator from 4 to 12 ounces of fluid, according to the tolerance of the bladder, are thrown in, wash-ing backward in its course the en-tire prostatic sinus, after which the catheter is gently patient now urinates out the contents of his bladder, thus giving himself a very efficient final retrojection.

URETHROTOMY FOR STRICTURE 587 In addition to this the patient should be given large quantitiesof water for several days before the operation, with the view ofmechanically cleansing the urinary passages. When an external urethrotomy is made, the precautions men-tioned are all carried out, and the bladder is drained as is de-scribed under Perineal Prostatectomy (page 573). Sectioning ofthe urethra for stricture is, in a large number of instances, fol-lowed by a chill and rise of temperature which is transient anddiseappears so rapidly that it is difficult to conceive the systemicdisturbance as being due to sepsis. There is, perhaps, a peculiarrelationship between trauma to the urethra and the toxemia whichfollows it. However, the fact that when cases are prepared in themanner stated the chill and rise of temperature does not, as a rule,obtain would suggest that t
