 dilatation of the blad-

 ter and kidneys. 



Hypertrophy of 

 the prostate may be

 the muscle and fibrous 

 tissue of the organ; 

 at the same time the 

 gland tissue may be 

 increased (Fig. 477), 

 or the latter may be 

 alone involved. The 

 increase in gland tis- 

 sue has usually the character of glandular hyperplasia.
