Weighted vaginal cones for urinary incontinence.

Area of Science:

• Urology
• Gynecology
• Rehabilitation Medicine

Background:

• Pelvic floor muscle training (PFMT) is a primary conservative treatment for stress urinary incontinence (SUI).
• Weighted vaginal cones offer a method to aid women in performing PFMT.
• Cones are inserted vaginally, with pelvic floor contractions used to retain them.

Purpose of the Study:

• To systematically evaluate the efficacy of weighted vaginal cones in managing urinary incontinence in women.
• To compare cone therapy with alternative treatments and placebo interventions.

Main Methods:

• A comprehensive literature search was conducted across major databases (Cochrane, MEDLINE, EMBASE) up to August 2001.
• Included were randomized and quasi-randomized controlled trials comparing weighted vaginal cones against other treatments or no treatment.
• Study selection, quality assessment, and data extraction were performed rigorously by multiple reviewers.

Main Results:

• Fifteen studies involving 1126 women were analyzed; 466 women used cones.
• Weighted vaginal cones demonstrated superiority over no active treatment for SUI.
• Evidence suggested comparable effectiveness between cones, PFMT, and electrostimulation, although confidence intervals were wide and study quality varied.

Conclusions:

• Weighted vaginal cones represent a viable treatment option for stress urinary incontinence, showing benefits compared to no treatment.
• The effectiveness of cones may be similar to PFMT and electrostimulation, but further high-quality research is essential.
• Patient adherence is a concern, highlighting the importance of offering cones as one of several available treatment options.
