Abstrakt     Lower urinary tract function relies on neural control the integrity of which is tested by clinical examination and several diagnostic methods, among them clinical neurophysiological tests. These comprise electrophysiologic methods of testing conduction through motor and sensory pathways (both peripheral and central), electromiografic methods, and quantitative sensory testing. The latter include tests of sensory thresholds for mechanical stimulation, vibration, temperature and electrical current; none of the tests (as applied to the urogenital area) have as yet proved of definite usefulness in the diagnosis of patients with incontinence. The text also reviews methods and findings of electrophysiological tests including EMG, sacral reflexes, responses recorded from muscle on stimulation of motor pathways (pudendal nerve, sacrat roots, motor cortex), and potentials recorded from sensory pathways (from nerve, roots, and cerebral cortex) after stimulation in the urogenital area. It is stressed that all electrophysiologic tests of conduction (terminal Iatency,motor-evoked potentials, sensory evoked porencials, and sacral reflexes) correlate with parency of the respective neural pathway, bur are not sensitive to partial neural system lesions of axonal type. The EMG signal can be used as an indicator of muscle activity patterns (kinesiological EMG) or can be analysed to reveal signs of muscle denervation by concentric reedle EMG (CNEMG) or signs of motor unit changes after reinnervation (CNEMG and single fibre EMG (SFEMG)). Clinical neurophysiological testing shoud be considered only in very selected groups of incontinent patients, particulary those with suspected or know involvement of neuromuscular system.
