INVESTIGATIONS ON DIETARY-TREATMENT OF STRUVITE UROLITHIASIS .3. EFFECT OF AN ACIDIFYING DIET ON ACID-BASE-BALANCE AND MINERAL-BALANCE OF CATS AFTER ACUTE URETHRAL OBSTRUCTION

The effect of a commercial acidifying diet on acid-base-balance and ur inary mineral concentration was compared in five healthy cats and five cats with urethral obstruction for six days after the removal of lowe r urinary tract obstruction. There were no significant differences in urine pH throughout the experiment between the groups. Blood pH was de creased in obstructed animals al the time of presentation at the clini c, but thereafter it did not differ from data from healthy cats on the same diet. The concentration of phosphorus and potassium in urine dec reased, sodium and chloride did not change, while magnesium and calciu m content increased.
