Even in this very simple operation, a certain dexterity is requisite; for the direction of all urethræ is not alike, and the mere pushing a bougie against a contracted part is not the only likely method of effecting a free passage. Much also depends upon the nature of the bougie—the elastic ones, although assisted in their attempted passage to the bladder, by the smooth and well lubricated sides of the urethra, have a tendency to straighten; and unless considerable rotatory motion be observed, are apt to hitch in a fold of the urethra, especially if the case befall a person of relaxed fibre, and he be much worn down by suffering. The bougies that I employ are constructed upon an improved plan to those in general use, being prepared of a material that will preserve the shape I adapt them to, previously to introducing them, but at the same time sufficiently soft to yield to any accidental tortuosity of the tube they are intended to explore. The bougie then is to be pressed softly, but steadily, against the obstruction, now and then withholding for a minute the bearing, so as to allow a respite to the stretched membrane; then renewing by, what is better done than expressed, an “insinuating” pressure for the space of the time advised above. The patient should not be dispirited, even if the bougie do not perforate the stricture at the first trial; it would doubtless do so, if longer time were employed, but that is rarely advisable, except in cases where the urine can scarcely escape, or much expedition be requisite. Should the operation even be unsuccessful in this first attempt, the patient will find his ability to micturate much greater than before the introduction; but, save in long-standing and obstinate strictures, I rarely find myself foiled, nor do those who practise the same method, if they have patience and skill enough, in overcoming the difficulty at the first interview. A great advantage of the cure by dilatation, independently of its safety and efficacy, is the insignificant pain it occasions; the sensation produced being only like a pressing desire to make water, which immediately subsides on withdrawing the bougie. Another method of dilating a stricture, where it happens to be of chronic existence, is the passing a plastic catheter into the bladder, and suffering it to remain all night, or even for several nights, stopping up the handle end with a cork or wooden peg, which the patient can remove when he desires to urinate. The urethra, by this means, becomes quickly dilated, and much beyond the size of the instrument. It necessarily confines the patient to his room and couch; but where an expeditious cure is the object, as much may be effected in this manner in six days, as by the ordinary method in as many weeks. Time, however, it must be remembered, is the working _material_ of nine tenths of strictured invalids, and a week’s lay-up may cost a twelve-month’s salary—a purchase too dear to be generally incurred.
