15%)
* Incontinence is rare and nocturia is absent
Subject has
2. an uroflow indicative of pathology other than OAB
3. monosymptomatic enuresis
4. dysfunctional voiding
5. bladder outlet obstruction, except if successfully treated

according to the modified Schwartz of < 60 mL/min per 1.73 m2)
16. a symptomatic (symptoms can include pain, fever, hematuria, new onset
foul-smelling urine) UTI. Note: if the UTI is treated successfully (clinical
