Urinary Calculi in Dogs

                    -----------------------

                      General Information



Urinary calculi are stone-like objects that form in the urinary

system.  The most common location for the buildup of these stones

is the urinary bladder.  The kidneys are the next most common

location for stone formation.  The most common type of bladder

stones form only in the presence of a urinary tract infection.

Some pets do not show any signs during the early stage of stone

formation, while others have such signs as frequent urination of

small quantities of urine, straining to urinate and blood in the

urine.  As the condition progresses, signs usually intensify.

Some pets may become unable to urinate.



Treatment of urinary calculi consists of removal of the stones,

either by dissolving them with a special diet or surgery, and

treatment of any infection.  After treatment, normal urinary

tract health must be maintained to prevent recurrence.



                 Important Points in Treatment



1.  Laboratory tests of the urine and blood are necessary to

    diagnose the condition and monitor the effectiveness of

    treatment.  Radiographs (x-ray) studies are used to confirm

    the presence of stones before treatment and their absence

    after treatment.



2.  Only certain types of stones can be dissolved with a special

    diet.  The doctor will advise you if this type of treatment

    is desirable for your pet.



3.  Give all medication as directed.  Call the doctor if you

    cannot give the medication.



4.  Diet:  If your pet's stones are being dissolved with dietary

    therapy, you must give no other foods, such as snacks, dog

    treats, rawhide chews, etc.  Do not give any other food

    materials during dietary therapy.



5.  Instructions for surgical patients:





        Notify the Doctor if Any of the Following Occur:



    * Your pet strains to urinate or cannot urinate.



    * Your pet has blood in the urine.



    * Your pet seems uncomfortable after urinating.
