Evaluation of female urinary incontinence device

Area of Science:

• Urology
• Biomedical Engineering
• Gynecology

Background:

• Stress urinary incontinence (SUI) is a common condition affecting women.
• Urethral sphincter dysfunction is a primary cause of genuine stress incontinence.
• Existing treatments for SUI have limitations, necessitating novel approaches.

Purpose of the Study:

• To evaluate the efficacy and impact of a new silicone rubber inflatable vaginal pessary.
• To assess the device's effect on subjective symptoms and urodynamic parameters in patients with SUI.
• To determine the feasibility of the pessary as a treatment for SUI.

Main Methods:

• A cohort of 33 patients with urodynamically confirmed genuine stress incontinence was enrolled.
• Patients used a silicone rubber inflatable vaginal pessary for one month.
• Subjective improvement was assessed, and urodynamic parameters, including maximum urethral closure pressure and bladder neck elevation, were measured.

Main Results:

• Nine out of 20 patients who used the pessary for one month reported subjective improvement.
• Two patients continued using the device beyond the initial study period.
• Urodynamic assessment revealed a significant increase in maximum urethral closure pressure and bladder neck elevation.

Conclusions:

• The silicone rubber inflatable vaginal pessary demonstrates potential as a conservative treatment for genuine stress incontinence.
• The device positively influences key urodynamic markers associated with urethral support.
• Further research is warranted to confirm long-term efficacy and patient satisfaction.
