Use of the Bulbocavernosus Reflex System in assessing voiding dysfunction.

Area of Science:

• Urology
• Neuroscience
• Diagnostic Medicine

Background:

• The bulbocavernosus reflex (BCR) is a physiological response that can be measured using the Bulbocavernosus Reflex System (BRS).
• Understanding the BCR's role in voiding dysfunction is crucial for accurate diagnosis and patient management.

Purpose of the Study:

• To evaluate the bulbocavernosus reflex (BCR) latency period as a predictor of specific voiding dysfunction patterns.
• To correlate BCR measurements with urodynamic (UDS) findings in men.

Main Methods:

• Eighty-seven men underwent evaluation using BRS, UDS, and electromyography.
• Multivariate logistic regression analyzed prolonged BCR latency (>45 ms) as a predictor for voiding dysfunction.
• Data included baseline characteristics, demographics, UDS results, and BCR latency parameters.

Main Results:

• The median age of participants was 70.4 years.
• Sixty-eight percent (78%) of men exhibited prolonged BCR latency (median 57.0 ms).
• Prolonged BCR latency did not show a significant association with detrusor overactivity (DO), bladder outlet obstruction (BOO), intrinsic sphincter deficiency (ISD), or detrusor sphincter dyssynergia (DSD).

Conclusions:

• Prolonged BCR latency is not a significant predictor of common voiding dysfunctions (DO, BOO, ISD, DSD) in this cohort.
• The specific diagnostic utility of BCR in evaluating voiding dysfunction remains uncertain.
• Larger prospective studies are required to elucidate the role of BCR in clinical practice.
