ABSTRACT

Uncomplicated urinary tract infection (UTI) is a bacterial infection of the bladder and associated structures. These are patients with no structural abnormality and no comorbidities, such as diabetes, immunocompromised, or pregnant. Uncomplicated UTI is also known as cystitis or lower UTI. Forty percent of women in the United States will develop a UTI during their lifetime, making it one of the most common infections in women. UTI is uncommon in circumcised males, and by definition, any male UTI is considered complicated. Many cases of uncomplicated UTI will resolve spontaneously, without treatment, but many patients seek treatment for symptoms. Treatment is aimed at preventing spread to the kidneys or developing into upper tract disease/pyelonephritis, which can cause the destruction of the delicate structures in the nephrons and lead to hypertension.

E.coli causes the majority of UTI but other organisms of importance include proteus, klebsiella, and enterococcus. The diagnosis of UTI is made from the clinical history and urinalysis, but the proper collection of the urine sample is important.
