How Do You Diagnose Recurrent Urinary Tract Infections and Confirm the Diagnosis?

초록

Recurrent urinary tract infections (UTIs) are the most prevalent conditions affected mainly by reinfection by the same bacteria in young women with no functional or anatomic problem. Recurrent UTIs present both storage (dysuria, irritative etc.) and voiding symptoms. For example, frequency subsequently followed by sexual intercourse is a powerful predictor of recurrent UTI. In patients with morbid situations or other factors, recurrent complicated infections or sepsis may be aggravated. Escherichia coli is the most common organism responsible for UTIs, but Pseudomonas, Proteus, Klebsiella, and other organisms are also frequent, particularly, in patients higher risk of complicated infections. Urine culture is not often needed to diagnose typical uncomplicated infection. Generally, urine culture with more than 10² colony-forming units/ml is used to diagnose UTIs in symptomatic patients. Recurrent UTIs could be managed with several techniques with the help of urine culture and by imaging studies when suspicious of anatomical abnormalities.
