In uncomplicated urinary tract disease, which reason(s) allow omitting a urine culture according to the material?

• A. Clinical signs have resolved
• B. The patient has a catheter with no clinical signs
• C. Both reasons
• D. Neither reason

Answer: (C)

The main idea is that urine culture isn’t needed when there’s no ongoing infection to guide. If clinical signs have resolved, there’s no evidence that continuing or repeating a urine culture will change management—the patient is clinically improving, so culture results wouldn’t alter the plan. In catheterized patients who show no symptoms, there’s a high chance of colonization or asymptomatic bacteriuria rather than a true infection; obtaining a culture in this situation won’t change treatment and can lead to unnecessary antibiotics and testing. Therefore, both scenarios describe situations where omitting a urine culture is appropriate. If symptoms were to persist or recur, culture would then be considered to tailor therapy.
