title: Microbiological look at urodynamic studies.
abstract: Urine samples were cultured for aerobic, fastidious, and anaerobic bacteria in 88 patients (66 F, 22 M) before and after standard urodynamic investigations. 37 of 42 women with detrusor instability, and 14 of 17 women with stress incontinence, had evidence of bacteriuria with aerobic or fastidious bacteria before investigation, as did 6 of 13 men with bladder outflow obstruction. 8 men (36%) acquired bacteriuria with aerobic bacteria after investigation, compared with 10 women (15%). Recalcitrant, irritative urinary symptoms in women may be caused by an underlying infection, the urodynamic changes being secondary. In men who have urodynamic studies, antibiotic prophylaxis should be considered.
