Suppression of bladder instability by penile squeeze

Area of Science:

• Urology
• Neuroscience
• Physiology

Background:

• Bladder instability causes involuntary detrusor contractions, leading to urinary urgency and frequency.
• Current management strategies for bladder instability have limitations and side effects.
• Investigating non-pharmacological interventions for bladder control is crucial.

Purpose of the Study:

• To evaluate the efficacy of penile squeeze technique in suppressing bladder instability.
• To compare the effects of penile squeeze with anal dilatation on bladder contractions.

Main Methods:

• Twenty male patients with diagnosed bladder instability participated.
• The penile squeeze technique involved applying pressure to the glans penis.
• Anal dilatation was used as a comparative mechanical stimulus.

Main Results:

• Penile squeeze successfully suppressed uninhibited bladder contractions in 17 out of 20 patients.
• Anal dilatation suppressed contractions in all 20 patients.
• Penile squeeze inhibited detrusor contractions during the contracting phase but did not affect bladder tonus.

Conclusions:

• Penile squeeze is a viable mechanical stimulus for suppressing detrusor overactivity in men.
• This technique offers a potential non-invasive method for managing bladder instability.
• Further research is warranted to explore the long-term effects and optimal application of penile squeeze.
