Because of a lack of published statistical data collected for large groups of patients, the reliability of monitoring for conus and cauda equina surgeries remains unclear. Anal mapping has been used in the past to identify the location of a sphincter defect before an anal sphincteroplasty in the treatment of fecal incontinence. The mean amplitude value was Whether the application of BCR monitoring is useful in terms of improvement of postoperative outcome has to be deduced from larger studies. Slowed conduction in the pudendal nerves in idiopathic neurogenic fecal incontience. Obstet Gynecol Clin North Am The asymmetrical distribution of ions between the inside negative and outside positive of a nerve cell creates a voltage potential that, when breached depolarization , allows the flow of current electrons.

Nevertheless, there is no doubt that during tumor resection in the conus or within the cauda equina, information about functional changes of the sacral reflex circuitry is relevant for the preservation of functional tissue. A randomized controlled trial. Nerve cell depolarization is an all-or-nothing event; therefore, across any one nerve fiber only a finite voltage potential can be established. EMG recording of the sacral reflex has been shown to be more reliable than the clinically assessed response e. Urodynamics often reveal absent bladder sensation and a hypoactive detrusor with elevated postvoid residuals.
