Follow-up cultures are not indicated if both of the following are present:
(1) the patient has one of the following:
(1a) asymptomatic bacteriuria
(1b) acute, uncomplicated cystitis
(1c) acute, uncomplicated pyelonephritis
(2) there is an appropriate clinical response to therapy
Follow-up cultures are indicated if:
(1) the infection has not responded to therapy
(2) there is a history of recurrent UTI
(3) there is an anatomic or functional abnormality of the urinary tract
(4) there are continued unexplained abnormalities on urinalysis
where:
• The presence of an anatomic or functional abnormality of the urinary tract usually indicates a complicated UTI (see sections 23.37.01 and 23.37.02, above).
• The abnormalities in urinalysis were not defined, but I would expect this would include a positive leukocyte esterase, nitrate, pyuria and/or bacteriuria.
