About

This study aims as defining success rate of the incontinence ring in women with test proven stress urinary incontinence and determining factors associated with successful use.

Full description

The primary objective of this study is to determine if the incontinence ring is effective in decreasing the incontinence episode frequency per week. Other objectives include the determination of the cure rate (objective and subjective) with the ring, the effects to bladder function as noted on urodynamic testing, the impact on quality of life and the acceptability to this device in the treatment of stress urinary incontinence.

In this cross-over study, 40 women will undergo a two-period treatment. In one of the periods, she will spend 4 weeks wearing continuously the ring and in the other (also 4 weeks duration), she will not be using any treatment for her incontinence. Between periods, she will spend 2 weeks in "wash out" to eliminate the risk of continuous effect from the treatment in the preceding period. Each woman will be randomly assigned to the treatment sequence.

Stress urinary incontinence is a common problem affecting at almost 20% of women. Treatments currently advocated include pelvic floor exercises and surgery. Pelvic floor exercises require great motivation and usually 3 months of training to show an impact. Surgery is very effective, but costly and carries a number of complications. The use of the incontinence ring may allow women to control their symptoms with immediate result at minimal risk. This device has never been properly evaluated before its introduction into the market.

Inclusion criteria

• Symptoms of urinary stress urinary incontinence (i.e. urinary leakage associated with increased intra-abdominal pressure/cough) (if mixed incontinence the urinary stress urinary incontinence symptoms must predominate)
• Urodynamic Stress urinary incontinence confirmed by urodynamic studies (i.e. urinary leakage associated with increased intra-abdominal pressure/cough in the absence of detrusor overactivity)
• Ability to understand spoken and written English

Exclusion criteria

• Severe pelvic organ prolapse (> or = stage 3 on the Pelvic Organ Prolapse Quantification System - POP-Q)
• Contraindications to pessary use (including acute vaginal/urinary or pelvic infections, vaginal or cervical lesions or unexplained vaginal bleeding)
• Inability to properly fit the incontinence ring

29 participants in 2 patient groups

Incontinence ring then no intervention

Experimental group

Description:

Participants first were fitted with an incontinence ring, which they wore continuously for 4 weeks. The ring wa then removed and a washout period of 2 weeks followed. Then the second 4-week period with no ring was completed.

Treatment:

No intervention then incontinence ring

Experimental group

Description:

Participants spend the first study 4-week period with no intervention. Then, a wasout period of 2 weeks followed. Participants were then fitted with an incontinence ring, which they wore continuously for 4 weeks.
