Urinary tract infections (UTI) are among the most common infections afflicting man. Urinary tract infections in young adult women are usually uncomplicated, but are often recurrent and cause considerable morbidity. Urinary tract infections in pregnant women, elderly patients, and catheterized patients warrant special attention because of their association with increased morbidity and possibly with increased mortality. Diagnosis of UTI is usually based on quantitation of uropathogens in voided urine. The traditional criteria for significant bacteriuria, greater than or equal to 10(5) uropathogens per ml of voided urine, is insensitive for detecting acute symptomatic cystitis in men and women and should be replaced with a lower colony count threshold.
尿路感染（UTI）是困扰人类的最常见感染之一。年轻成年女性的尿路感染通常并不复杂，但往往会反复发作，并导致相当高的发病率。孕妇、老年患者和留置导尿管患者的尿路感染因其与发病率增加以及可能的死亡率增加相关而值得特别关注。UTI的诊断通常基于对排尿中尿路病原体的定量。传统的显著菌尿标准，即每毫升排尿中尿路病原体大于或等于10⁵，对于检测男性和女性的急性症状性膀胱炎并不敏感，应该用更低的菌落计数阈值来取代。
