The practice of surgery . 486 CALCULUS IN THE FEMALE. and because, the urethra being short, capacious, straight, and well-flooded, extrusion of renal formations is more probable than their reten-tion. Nuclei are not unfrequently afforded, however, by the introduc-tion of foreign matters from without; and these substances may be ofbulk and form not favorable to extrusion under any circumstances;bodkins, pencils, glass stoppers, coal, sandstone, &c. When a stone does form, and remains, the symptoms it occasionsare quite analogous to those in the male. Perquisition is made by ashort, straight, steel staff, slightly curved at the extremity. And astone, having been found, may generally be got rid of without urethra admits of great dilatation; and if this be done gradually,but little pain is caused. Sponge-tent, Weisss metallic dilator, or [Fig. 219.]. [Weisss Metallic Dilator; the black lines show the instrument closed: the dotted lines represent the bladesexpanded by turning the screw, which is connected with the handle. (From Fenuisson.)—Ed.] Arnotts fluid dilator, may be employed. And a sufficiency of spacehaving been so obtained, forceps or a scoop are introduced, and thestone removed. The risk is, that, in consequence of the dilatation,power of retention may be seriously impaired, and more or less incon-venience by incontinence of urine may result. Lithotripsy was at one time supposed unsuitable to the female; butexperience has shown that it is fully as applicable as to the male—theshortness and amplitude of the urethra favoring, indeed, the introduc-tion and efficient play of the instruments. Subsequent expulsion of thefragments, too, is more easy and If the stone be found of larger size than to pass by dilatation alone,and if lithotripsy should not be considered advisable, the knife is to beused—sparingly.
