Results: Recruitment of 51 patients: urinary urgency (58%), nocturia (66%), stress urinary incontinence (45%), daytime urinary frequency (15%), enuresis (7%), dysuria (27%). Urodynamic studies show overactive detrusor (57%) with and without detrusor-external sphincter dyssynergia (42%), or intrinsic sphincter deficiency (42%). Dysuria (42%) at flow determination.
