Traces: making sense of urodynamics testing--part 3: electromyography of the pelvic floor muscles
1Department of Urology, University of Virginia, Charlottesville, VA, USA.
Abstract:
Electromyography (EMG) of the pelvic floor muscles is a valuable but challenging component of urodynamics testing. Optimal assessment relies on thoughtful selection of needle, wire, or surface patch electrodes; consistent display of EMG tracings simultaneously with pressure and flow tracings; and minimization of technical and environmental artifacts. This article reviews technical aspects of EMG, including the selection of the best electrodes for a given clinical scenario, minimization of environmental and technical artifacts, and clinical measurement during the filling cystometrogram and voiding pressure flow study.

Muscles of the Pelvic Floor and Perineum
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
