Urinary tract infection
This chapter on urinary tract infections brings up to date advice on the aetiology, diagnosis, and management of urinary tract infections in adults. The microbiology of this common presentation is discussed, together with recent patterns of resistance. Different clinical presentations are highlighted: lower UTI, upper UTI, asymptomatic bacteriuria, pregnancy, catheterized patients, haematuria, the elderly, urethral syndrome, interstitial cystitis and drug-induced cystitis. The role of different diagnostic tests, in particular routine urine culture, is explored. Guidance on the management of different clinical presentations of UTI is given, as well as an outline of the options for reducing the frequency of recurrent UTI in those so predisposed.
