Detrusor-external sphincter dyssynergia: a detailed electromyographic study
Abstract:
We reviewed 54 cases of detrusor-external sphincter dyssynergia following complete urodynamic evaluations. All patients had well defined neurologic lesions of the suprasacral spinal cord. On the basis of urodynamic findings 3 types of dyssynergia were encountered: type 1 (30 per cent) was characterized by a crescendo increase in electromyographic activity that reached a maximum at the peak of the detrusor contraction, type 2 (15 per cent) consisted of clonic sphincter contractions interspersed throughout the detrusor contraction and type 3 (55 per cent) was characterized by a sustained sphincter contraction that coincided with the detrusor contraction. There was no correlation between the clinical neurologic level and the type of dyssynergia.

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...
