Detrusor sphincter dyssynergia (DSD) involves simultaneous bladder muscle contraction and involuntary urethral sphincter tightening, often seen after spinal cord injuries. This condition causes high bladder pressures and incomplete emptying, potentially leading to serious complications if not managed.
Area of Science:
- Urology
- Neuroscience
- Physiology
Background:
- Detrusor sphincter dyssynergia (DSD) is a condition characterized by involuntary contraction of the urethral sphincter during bladder voiding.
- It typically occurs in patients with spinal cord lesions above the sacral level.
- This dyssynergia leads to elevated intravesical voiding pressures and significant post-void residual volumes.
Purpose of the Study:
- To define Detrusor Sphincter Dyssynergia (DSD).
- To explain the pathophysiology and consequences of DSD.
- To review current treatment approaches for DSD.
Main Methods:
- Literature review on DSD pathophysiology and clinical presentation.
- Analysis of complications associated with untreated DSD.
- Evaluation of current therapeutic strategies for symptomatic management.
Main Results:
- DSD is defined by concurrent detrusor contraction and involuntary urethral sphincter contraction.
- High urethral closure pressures during voiding lead to high intravesical pressures and large post-void residuals.
- Untreated DSD can result in significant complications in up to 50% of affected patients.
Conclusions:
- DSD poses a significant risk of complications due to high voiding pressures and incomplete bladder emptying.
- Current treatments primarily focus on managing symptoms rather than addressing the root causes of DSD.
- Regular follow-up and management are crucial for patients with DSD to prevent severe complications.

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...
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...
