Prognosis and Follow-up for Pets with Urinary Tract Infections
The symptoms of your pet's urinary tract infection will usually dramatically decrease within two to four days of therapy. Prognosis of a cure for simple urinary tract infections is excellent after a two-week course of therapy. A follow-up urine analysis should be done five to seven days after antibiotic therapy is completed to evaluate for persistent, unresolved, or recurrent infection. If your pet's infections are not adequately controlled, long-term complications including deep-seated kidney infections and pain may occur. In cases that recur or with prolonged symptoms, it is important to have a complete medical examination to evaluate for underlying causes that need to be addressed. In cases where physical exam and diagnostic testing fail to determine underlying causes, long-term therapeutic options including daily, low-dose antibiotic therapy at bedtime may be tried. In other cases, five to seven-day full course antibiotic therapy each month (known as pulse therapy) is another common long-term treatment option.
Urine analysis, urine culture, and X-rays will likely be repeated intermittently in pets with a history of chronic or recurrent urinary tract infections. While a cure may not be possible in these cases, palliative symptomatic control is often achieved with frequent re-evaluations.
