Abstract

Urinary tract infection is the most frequent bacterial infection. Acute uncomplicated urinary infection and acute non-obstructive pyelonephritis occur in young women with normal genitourinary tracts. Empirical short-course therapy is preferred for the management of acute cystitis, but evolving resistance requires continuing reassessment of optimal antimicrobial selection. Empirical trimethoprim or trimethoprim/sulfamethoxazole has been recommended, but increasing resistance to these agents suggests that pivmecillinam, nitrofurantoin and perhaps fosfomycin trometamol should be considered. Although flouroquinolones are effective as short-course therapy, widespread empirical use of these agents should be discouraged because of potential promotion of resistance. For acute non-obstructive pyelonephritis, flouroquinolones are the empirical oral treatment of choice, although urine culture results should direct continuing therapy. Complicated urinary tract infection occurs in men or women of all ages with underlying abnormalities of the genitourinary tract. Treatment of complicated urinary infection is individualised, taking into consideration the underlying abnormality and susceptibilities of the infecting organism. Asymptomatic bacteriuria should not be treated except in pregnant women, in patients prior to undergoing an invasive surgical procedure, or renal transplant recipients in the early postrenal transplant period.
