The presence of calculi may be ascertained by a manual exam-

PROTRUSION AND INVERSION OF THE BLADDER. > 



This is usually a consequence of difficult labor, though it has 

 been known to result from excessive doses of diuretic medicines. 



The treatment calls for consider-

passage through which it is to be 

 pressed. Then the thumbs are alternately pressed upon the center 

 of the fundus, and portion after portion is pressed on. When it 

 enters the vagina, the whole is directed through the valvular open- 

 ing to its original position within the pelvis. Pressure should be 

 applied only during the passive states, as, if applied when the ani- 

 mal is straining, there is danger of rupturing the bladder. The 

 rent in the vagina, if there is one, must be closed by sutures, and 

 the whole vagina lubricated two or three times a day with carbol- 

 ized oil. The straining must be arrested ; if anodynes fail to ac- 

 complish this, the Delwart truss (Fig. 1091) must be put on. In 

 some cases the use of a hollow pessary will be of advantage.
