Many studies have discussed clinical practice guidelines for the treatment of cystitis and pyelonephritis. Treatment of uncomplicated urinary tract infections (UTIs) can be based on empiric antibiotic therapy. For complicated or recurrent UTIs, therapy can be based on laboratory-controlled culture and sensitivity (C&S) reports. The diagnosis of UTI by clinical criteria alone has an error rate of up to 33%. In addition, positive laboratory culture results do not always indicate a diagnosis of UTI. Comparison of urine in a conventional culture model versus DNA next-generation sequencing (NGS) to accurately identify and provide information on resistance factors (mobile genetic elements) is warranted. Our study was a head-to-head comparative phase II study of standard urine C&S versus DNA NGS testing for the diagnosis and treatment efficacy in patients with symptoms of acute cystitis based on short-term outcomes.
