Having enumerated what I believe to be the simple prin- ciples of lithotrity, I will further illustrate the practice. Usually, when you have a large stone to deal with, it is necessary to begin with the fenestrated instrument—that is, one in which the female blade is entirely perforated, allowing the male to pass through it. This is always a more or less dangerous instrument; hence it is used as little as possible (Fig. 18). I never use it unless the stone is actually so large Fig. 18.—The fenestrated lithotrite. that it cannot be crushed by the flat-bladed instrument. The edges of the instrument exactly meet, and are sharp, and the fragments made by it are always rough and irritating. Always, when it is possible, I use the lithotrite with flat blades —blades which reduce the stone to powder (Figs. 19 and 20). The blades do not meet each other, and cannot catch or hurt the bladder, and the movement altogether is easier than that of the other instrument.

You know that in passing a catheter, we, in this country, stand on the left side of the patient; in France, the surgeon stands on the right side.
