Electrophysiological techniques for the study of urethral and vesical innervation.

A new electrophysiological technique for the study of urethral and vesical innervation is reported. The method gives valuable information on the structural integrity and function of two of the reflex arcs involved in micturition. Normal and pathological patterns are described, illustrating the diagnostic value of the method in the assessment of neurogenic disturbances of bladder and urethral function.
