In most cases, the evaluation of urinary incontinence requires only a
history, a physical examination, urinalysis and measurement of postvoi
d residual urine volume. The initial purposes of the evaluation are to
identify conditions requiring referral or specialized work-up and to
detect and treat reversible causes that may be present. If the patient
does not appear to require referral and a reversible cause is not ide
ntified, the next step is to categorize the patient's symptoms as typi
cal of either urge or stress incontinence and treat the patient accord
ingly. If treatment fails or a presumptive diagnosis of urge or stress
incontinence cannot be reached, the final step would be to perform mo
re sophisticated tests or refer the patient for testing to define the
cause and determine the best treatment.
