New intravaginal device supports bladder neck, controls stress incontinence


NEW YORK (Reuters Health) – A new disposable intravaginal device controls stress incontinence better and is preferred over the currently available device from the same manufacturer, according to results of a prospective crossover study.

The new device, the Contrelle Continence Tampon (Coloplast a/s, Humlebaek, Denmark) is made of hydrophobic polyurethane, is packed within an applicator, and is inserted into the vagina much the same way as a sanitary tampon. The older Conveen Continence Guard is made of hydrophilic polyurethane, requires soaking in water, and must be placed on an applicator before insertion.

Sixty-two women with stress incontinence but no major uterovaginal prolapse participated in the study. Dr. H. Thyssen, of Glostrup Hospital in Denmark, and associates in Australia and the UK, randomized subjects to try each device for periods of 5 weeks each. The results appear in the December issue of the British Journal of Urology International.

At baseline, a 24-hour pad test showed a mean loss of 43.1g. The Conveen reduced this to 20.2 g, while the result with the Contrelle was 10.8g.

"The frequency of micturition, flow rates and urinary residual volumes were not significantly changed when using either of the two devices" the researchers note. The Contrelle was preferred by 63% of women by the end of the study, while 26% preferred the Conveen, 5% found them equally good, and 5% would not use either one.

Vaginal cultures at each visit were normal. Two women developed asymptomatic bacteriuria during the course of the trial. No cases of toxic shock syndrome developed.

Dr. Thyssen's group recommends the device for those wishing to avoid or who are awaiting surgical intervention. "Such devices may allow women to return to a normal level of activity or sport without resorting to surgery," they conclude.
