detrusor-external sphincter dyssynergia

Pronunciation: dis-sin-ER-jee-ah

Also written as: DESD — Detrusor-External Sphincter Dyssynergia

Neurological condition where bladder muscle and external sphincter contract simultaneously, preventing normal voiding.

Full Definition

Detrusor-external sphincter dyssynergia (DESD) is a neurogenic voiding disorder characterized by simultaneous contraction of the detrusor muscle and external urethral sphincter during attempted voiding. This incoordination results in high voiding pressures, incomplete bladder emptying, and potential upper tract deterioration. DESD typically occurs in patients with spinal cord injuries, myelomeningocele, or other neurological conditions affecting the coordination between the central nervous system and lower urinary tract. Treatment may include anticholinergics, clean intermittent catheterization, or surgical interventions.

Usage

Usage note: Often abbreviated as DESD in clinical documentation.
