Penile urethral compression-release maneuver as a non-invasive screening test for diagnosing prostatic obstruction

Area of Science:

• Urology
• Medical Devices
• Diagnostic Tools

Background:

• Voiding dysfunction and prostatic obstruction are common in adult men.
• Current diagnostic methods can be invasive and costly.
• A need exists for simple, non-invasive screening tools.

Purpose of the Study:

• To evaluate the feasibility of a penile urethral compression and quick release maneuver.
• To assess its potential as a non-invasive screening tool for voiding dysfunction and prostatic obstruction.
• To analyze the penile compression-release index in relation to different voiding conditions.

Main Methods:

• A penile compression-release maneuver was performed during urination in men with and without voiding dysfunction.
• The penile compression-release index was calculated based on flow rate changes.
• Urodynamic studies were conducted for comparison and validation.

Main Results:

• The penile compression-release index was significantly higher in patients with bladder outlet obstruction or detrusor instability compared to controls.
• The maneuver differentiated prostatic obstruction from other causes of low urinary flow rates.
• Results suggest the maneuver's sensitivity to outlet status and detrusor contractility.

Conclusions:

• The penile compression-release maneuver is a feasible, non-invasive technique.
• It shows potential for screening patients with voiding dysfunction and diagnosing prostatic obstruction.
• Further research in larger cohorts is needed to confirm clinical utility.
