DISEASES OF THE URINAEY OEGANS. 



SUPPRESSION AND RETENTION OP THE URINE. 



Suppression of the urine is sometimes called ^'•stopimge of 

 watery The water may not pass at all, or part of it may 

 dribble av,'ay, but not sufficient to give relief. There is a dif- 

 ference between supj)ression and retention, important to be 

 remembered. In suppression of the urine, the kidneys do not 

 secrete any water, or but very little ; in retention of the urine, 

 the water is properly secreted by the kidneys and j^oured into 

 the bladder, but is not passed oif, or only a part of it dribbled 

 away. 



Symptoms. — The most marked symptoms of these troubles 

 are explained in the above description. Much pain, straddling 

 movement, eiforts to pass water, and much the same symp- 

 toms that attend inflammation of the kidneys or bladder, at- 

 tend these troubles. They are, indeed, the attendants or 

 symptoms of other diseases ; though, from the evil they may 

 do, require medicine given, or means made use of for their 

 relief. 



To ascertain whether the case is one of retention or sup- 

 pression of the urine, the hand must be passed into the rec- 

 tum or last gut, when the bladder will be felt lying beneath it. 

 If the bladder is found empty, or nearly so, and soft, the case 

 is one of suppression of the urine. But if the bladder is large 

 and hard, showing that it has a great quantity of water in it, 

 the case is one of retention. 



Causes. — Retention of the urine is the result of strangury,
