| Popis: | Objective: Somatosensory evoked potential (SSEP) is an electrophysiological test used to evaluate sensory innervations inperipheral and central neuropathies. Pudendal SSEP has been studied in dysfunctions related to the lower urinary tract andpelvic floor. Although some authors have already described technical details pertaining to the method, the standardizationand the influence of physiological variables in normative values have not yet been established, especially for women. Theaim of the study was to describe normal values of the pudendal SSEP and to compare technical details with those describedby other authors.Materials and Methods: The clitoral sensory threshold and pudendal SSEP latency was accomplished in 38 normal volun-teers. The results obtained from stimulation performed on each side of the clitoris were compared to ages, body mass index(BMI) and number of pregnancies.Results: The values of clitoral sensory threshold and P1 latency with clitoral left stimulation were respectively, 3.64 ± 1.01mA and 37.68 ± 2.60 ms. Results obtained with clitoral right stimulation were 3.84 ± 1.53 mA and 37.42 ± 3.12 ms, respectively.There were no correlations between clitoral sensory threshold and P1 latency with age, BMI or height of the volunteers. Asignificant difference was found in P1 latency between nulliparous women and volunteers who had been previouslysubmitted to cesarean section.Conclusions: The SSEP latency represents an accessible and reproducible method to investigate the afferent pathwaysfrom the genitourinary tract. These results could be used as normative values in studies involving genitourinary neuropa-thies in order to better clarify voiding and sexual dysfunctions in females.Key words: neurophysiology; pelvic floor; evoked potentials; electrodiagnosisInt Braz J Urol. 2007; 33: 815-21 |
