Urinary tract infections in the adult. The Postgraduate Medicine Lecture.

Diagnosis of urinary tract infection should be made only on the basis of complete evidence. Examination and culture of the urine are necessary steps in correct diagnosis and treatment. Urinary obstruction is almost always present in recurrent infections. Contributory factors include sex practices conducive to entry of bacteria, poor perineal hygiene, occupations that require long periods of driving or riding, chronic constipation, and use of oral contraceptives, tampons, and douches. Many antibacterial drugs are effective in eliminating infection. Contributing factors should be modified or eliminated to prevent recurrence.
