Sažetak
We examined 100 patients over 5 years. FIfty of them had no urinary roblem while the other half suffered from incontinence. Detection EMG was performed by the use of a needle electrode which was placed directly in the anal and external urethral sphincter. Neurography of pudendal nerve was carried out by applying Chantraines method but it was modified. Normal motor conduction velocity of pudendal nerve was 45 m/s. Sphincter examination showed that action potentials were more polyphasic, shorter and of higher freqvency than those obtained from sceletal muscles. They were the same as those found in the muscles with high difference function. We also found that in the state of relaxation there was a tonic activity which stoped during a state of maximal relaxation and was again reactivated at volontary action. With agging potentials become more polyphasic and were of longer duration. in the patients with polyneuropathy action potentials had higher amplitude and lasted longer. Pudendal conduction velocity was reduced. In myopatic patients findings were different. In spastic paraplegia EMG and neurographic findings were normal. In cases of compressive syndrome of cauda equina caused by prolapse of intervertebral disc, and in syndrome of genital organe prolapse, electrophydiologic examination gave results identical to those in the lesions of peripheral nerves. EMG and neruographic findings of the pudendal nerve were normal in the patients suffering from stress incontinence, idiopatic foecal incontinence and sexual impotence. We tried to standardise EMG of external urethral and anal sphincter and pudendal nerve conduction velocity in normal patients without urinary problems. We also monitored patients with neurologic diseases accompanied by incontinence.
