The aim of this study was to evaluate the efficacy of the Contiform intravaginal device for stress incontinence after the addition of a fourth size. We offered the device to a cohort of 73 women with a main complaint of stress incontinence but no prolapse. Of the 73 women invited to participate, 65 enrolled, of whom 52 were fitted. Of these 52 women, 37 (71%) completed the study protocol. Outcome measures were the 24-h pad test, St George score, and quality of life tests. Urine loss on pad test was significantly reduced from a median 6.6 g (interquartile range [IQR] = 4.3–22.6) to 2.2 g (IQR = 0.5–8.2; P = 0.0016) after 4 weeks with significant benefit seen on the Incontinence Impact Questionnaire and Urinary Distress Inventory. The insertion technique was quickly learnt, and the device was well tolerated. The recently developed medium/large size of Contiform was used by 6/37 (16%) women.
