title: Contelle: pelvic floor stimulator for female stress-urge incontinence. A multicenter study.
abstract: The clinical efficacy of a new device for treatment of female incontinence was studied in a multicenter trial. The device consists of an inflatable electrode carrier and an external stimulator unit. Forty women were treated: 10 had primary or recurrent genuine stress incontinence, 15 had urge incontinence due to idiopathic detrusor instability, not responding to drug treatment, and 15 had stress incontinence combined with detrusor instability. Twenty-five patients were improved by the treatment. Another 8 reported an excellent result of treatment and remained free of symptoms for more than six months after withdrawal of the treatment. The results were more favorable in patients with bladder hyperactivity than in genuine stress incontinence. The patients' general ratings of treatment efficacy correlated well with their recordings of urinary frequency and consumption of incontinence pads. The functional bladder capacity increased in improved patients, but normalization of urodynamic parameters was no prerequisite for clinical improvement. We found intravaginal electrical stimulation to be a valuable alternative to medical and surgical intervention in patients with detrusor instability.
