The article analyses problems of diagnosis and treatment of neurogenic disorders of urination in the group of patients operated for prostatic pathology, the role of the conduction system of the corticospinal tract and conductive potential of perineal muscles in the above patients. Main standard electromyographic parameters were established by the data of examination of 7 controls--latency of the cortical and segmental evoked motor response, time of central motor conduction, amplitude of potentials of motor unities. Fifteen patients with prostatic diseases showed severe disorders of both corticospinal conduction and perineal muscular contraction. Patients with prostatic cancer or adenoma treated with different methods had denervation changes in pelvic inferior muscle in unaffected corticospinal conduction. Denervation changes after surgical treatment for prostatic cancer and delay of reinnervation, recovery of nervous control may be determined not only by the fact of operation but also by the course of the underling disease. Examination of the pelvic inferior muscles demonstrated that HIFU is a traumatic treatment of prostatic cancer because of extention of the physical impact beyond the prostate on muscular-nervous structures. These denervation muscular changes should be taken into consideration in assessment of the patient's condition and choice of treatment policy.
