Abstract
Detailed electromyographic [EMG] investigation of the external urethral sphincter was done as part of a urodynamic evaluation of 119 patients. The sphincter was located by inserting electrodes alongside the urethra. The EMG was viewed on an oscilloscope and recorded on paper. Normal and abnormal sphincter EMG were defined and the role of sphincter EMG in urodynamic studies was discussed. EMG activity did not always correlate with urethral resistance but was interpreted in conjunction with other urodynamic parameters, such as urethral pressures, urinary flow rates and voiding cystourethrography. Sphincter EMG provided valuable information to define the various neural pathways involved in micturition and continence.This publication has 15 references indexed in Scilit:
