96 CANINE MEDICINE AND SURGERY 



Symptoms. — In the early stages, hematuria may 

 result from tumors of the bladder, but later there 

 is pain on urination and the usual symptoms of 

 cystitis. In the last stages the patient becomes 

 emaciated and anemic, and the urine fetid and puru- 

 lent. The presence of the tumor may be diagnosed 

 by the use of the catheter or sound, and by rectal 

 examination. 



Treatment. — Treatment consists of suprapubic 

 cystotomy and removal of the, new growth. This 

 operation is described on page 213. 



In the majority of the cases the prognosis is un- 

 favorable. 



Prolapse 



This accident occurs only when the lower wall 

 of the vagina has been ruptured during parturition. 

 The bladder escapes through the rent and may pro- 

 ject beyond the vulva. The condition may be dis- 

 tinguished from eversion of the bladder by the fact 

 that the bladder is covered with serous membrane 

 and contains urine or gradually fills up with urine. 

 In inversion, the bladder is turned inside out, the 

 mucous coat being exposed, and the openings of 

 the ureters, from which drops of urine will be dis- 

 charged, are easily seen. In addition, examination 

 of the vaginal floor reveals the rupture through 

 which the organ has protruded. 



If prolapse of the bladder is neglected, inflamma- 

 tion followed by necrotic changes will take place in 

 the bladder walls, rendering the prognosis grave. 



Treatment. — Provided the serous coat is little 

 changed, it must be carefully cleaned with anti- 

 septics, emptied of its contents and pushed back 

 into position, and the tear in the vagina sutured. 

 The patient should then receive an anodyne to pre- 

 vent straining.
