Aim: The aim of this study was to present our preliminary experience with intraoperative neuromonitoring during rectal resection. Materials and methods: We qualified 4 patients (2 women, 2 men; age 42 – 53 years) cancer for surgery neuromonitoring. In all patients, functional tests the anorectal area were performed before surgery. Action potentials from sphincter complex in response nerve fiber stimulation recorded electrodes implanted Moreover, we inserted a standard, 18FR Foley’s urinary catheter which T-tube connected allow urine outflow measurement pressure changes bladder induced by detrusor contractions stimulation. Results: Setting up prolonged time 30 40 minutes, or even 60 80 minutes case first two patients. Neuromonitoring itself took additional 20 stimulated branches inferior hypogastric plexus their anatomical position dissection. three evoked responses both planes one patient, there no left side bladder, same observed symptoms neurogenic bladder. Conclusions: Based on available literature own experience, state that monitoring electromyographic signals sphincters enables visualization preservation autonomic nervous system structures, sympathetic parasympathetic. Intraoperative seem be correlated clinical presentation examinations after order objectify results, it is necessary perform larger group
