Complicated pyelonephritis, acute epididymitis and acute prostatitis are febrile urogenital infections. Because the elderly person often has an underlying disease, urogenital tract infec- tions of the elderly persons are complicated urinary tract infections in most cases. However, in the elderly people, clear findings that are characteristic of urogenital infections are not often obtained in the physical examination. If the clear findings of urogenital infections with pyuria and bacteriuria by urinalysis were not obtained, we should treat the infections accord- ing to guidelines as the urogenital infections after having denied other site of infection such as the respiratory tract infections or biliary tract infections. It is important to never diagnose the urogenital infections only by the urinalysis not to be possible of the regional diagnosis.
