In clinical urology Rose and his co-workers1 made studies of the urinary bladder by means of the cystometer, an instrument which records synchronously the intracystic capacity and pressure. The results seemed to indicate that valuable diagnostic criteria with respect to neurogenic lesions of the bladder could be obtained in this manner. These investigators classified neurogenic dysfunctions of the bladder cystometrically into those caused by (1) irritation or destruction of the sympathetic, (2) irritation or destruction of the parasympathetic, (3) interference with the function of the nervus pudendus, (4) lesions of the central nervous system above the origin of the thoracolumbar (second dorsal) spinal segment, (5) psychic (hysterical) bladder, (6) reflex mechanism seen in cases of postoperative retention and (7) intraspinal or extraspinal injury provided the lesion affects one of the reflex areas of innervation of the bladder.
In general, cystometric curves were interpreted as representing parasympathetic or sympathetic overbalance
