Regarding the diagnosis of asymptomatic bacteriuria all the following are true, EXCEPT:a. For women, a count of ≥105 cfu/mL in voided volume in two consecutive samples is diagnostic
For asymptomatic bacteriuria in women a count of ≥105 cfu/mL in voided volume in two consecutive samples is diagnostic, whereas only one sample is needed to be diagnostic for a man with no urinary symptoms In a single catheterised sample, a count may be as low as 102 cfu/mL to be diagnostic. The count can be slightly higher at 103 cfu/mL for an ‘in and out’ catheter or convene/condom catheter sample to be diagnostic.
Asymptomatic bacteriuria should only be treated in pregnant women or prior to transurethral surgery with a risk of mucosal bleeding. Essential read: EAU guidelines on Urological Infections and NICE Quality Standards (QS90), List of Quality Statements (Urinary tract infections in adults).
