  A complicated urinary tract infection is a urinary infection that occurs in a patient who has a genitourinary tract structural or functional abnormality. Complicated urinary infections can be linked to a wide range of genitourinary abnormalities. Interference with normal voiding is the most common cause of disease, as it prevents bacteria from being flushed out of the genitourinary tract. Infection can be caused by incomplete urinary drainage, the persistence of bacteria in biofilm on stones or indwelling devices, or increased organism introduction into the genitourinary tract due to instrumentation. The risk of disease varies depending on the abnormality. A chronic indwelling catheter, for example, is always associated with bacteriuria, whereas disease caused by a single obstructing ureteric stone can be transient, especially when the stone is removed. The prevalence of bacteriuria is very high, reaching 100% in patients with chronic indwelling catheters, 30% to 40% in patient...
