Nineteen among 40 had residual urine of 30 approximately 470 ml, on the average 135 ml. Among 42 one had high and 3 had low maximal urethral closure pressures. Bladder capacity at maximal sensation was below 200 ml in 20 and over 600 ml in 2. Electromyography showed 10 had detrusor-sphincter dyssynergia, 4 had uninhibited sphincter relaxation and 14 had brisk bulbocavernosus reflex. 3) Judging from the above results 25 over 42 patients (59.5%) had on the average a moderate degree of evacuation disturbance and 37 over 42 patients (88.1%) had on the average a severe degree of storage disturbance.
