OBJECTIVES: To determine whether or not an improved hygiene can lessen the incidence of symptomatic urinary tract infections (UTIs) in patients treated by cystectomy for urinary bladder cancer. PATIENTS AND METHODS: We attempted to contact during their follow-up all men and women aged 30-80 years who had undergone cystectomy and urinary diversion at seven Swedish hospitals. During a qualitative phase we identified hygienic measures and included them in a study-specific questionnaire. The patients completed the questionnaire at home. Outcome variables were dichotomized and the results presented as relative risks (RR) with 95% confidence interval. RESULTS: We received the questionnaire from 452 (92%) of 491 identified patients. The proportion of patients who had a symptomatic UTI in the previous year was 22% for orthotopic neobladder and cutaneous continent reservoir, and 23% for non-continent urostomy diversion. The RR for a UTI was 1.1 (0.5-2.5) for 'never washing hands' before handling with catheters or ostomy material. Patients with diabetes mellitus had a RR of 2.1 (1.4-3.2) for having a symptomatic UTI. CONCLUSIONS: We could not confirm lack of hygiene measures as a cause of UTI for men and women who had a cystectomy with urinary diversion. Patients with diabetes mellitus have a greater risk of contracting a UTI.
