Treating urinary tract infections can take time
Jul 01, 2003
Signalment: Canine, Greyhound, 2.5 years old, female spayed, 65 lbs.
Physical examination: The findings include rectal temperature 101.8° F, heart rate 124/min, pink mucous membranes, and normal capillary refill time. The dog is bright, alert, and responsive. Normal heart and lung sounds are heard.
Radiograph examination: The lateral abdominal radiograph shows gaseous distension of the intestinal tract.
My comments: The liver shows a decreased inhomogeneous texture in its parenchyma. No masses noted within the liver parenchyma. The gall bladder is mildly distended, and its walls are not thickened or hyperechoic.
There are blood clots attached to the urinary bladder wall. When the dog changed position, the right ureter was clearly seen as it enters the urinary bladder. The left and right adrenal glands are similar in size and shape.
Case management: In this case, ascending urinary tract infection contributing to recurrent pyelonephritis is the clinical diagnosis.
The way I generally manage recurrent urinary tract infections as in this dog is as follows.
Thereafter, the dog receives a single standard dose of the respondent antibiotic each evening after complete emptying of the urinary bladder for the night, usually for most people around 10 to 11 o'clock.
With administering the antibiotic agent to the dog each evening it should concentrate in the collecting urine during the night for an immediate antimicrobial effect and should help maintain a delayed antibiotic effect that is known to occur with many antibiotic agents in the urinary tract.
