Results of urodynamic studies. Simultaneous recordings of intravesical pressure (Pves) and external urethral sphincter EMG. Bladder volume at first desire to void (FDV) was 200 ml and at maximum desire to void (MDV) 500 ml. There is no detrusor hyperreflexia. During voluntary micturition (VOID), the detrusor pressure rise was insufficient, evidence of hypocontractile bladder on voiding. EMG activity has disappeared, and there is no detrusor-sphincter dyssynergia (DSD).
