Introduction and hypothesis: The continence dish has been a treatment option since 2002 for women with stress urinary incontinence (SUI) who decline surgery, but few quantitative objective efficacy data are published. We aimed to determine the efficacy and acceptability of this device for pure SUI or mixed incontinence (MUI).
Methods: Prospective interventional cohort study of 100 women with SUI or stress-predominant MUI who were interested to use the device; International Consultation on Incontinence Questionnaire (ICIQ) was primary outcome measure; 24-h pad test and Incontinence Impact Questionnaire (IIQ) were secondary outcomes. Acceptability was determined by device retention for 4 weeks, adverse events and ability to self-insert the device.
Results: Of 100 suitable women, 9 were not actually fitted, and 27 did not complete (acceptability: 64/100). The rate of adverse events was 7.7%, with 62.5% of users able to self-insert the device: 22 (34%) had pure SUI; 66% had MUI. In SUI, 68% were 'dry' on ICIQ median value 4.0 (IQR 2.5-8.5); 88% were dry on 24-h pad test (median 0.0, IQR 0.0-8.5). The "dry rate" was lower in MUI: 36% for ICIQ (median 9.0, IQR 5.0-15.0) and 62% for 24-h pad test (median 6.2, IQR 0.95-19.7). A "good" response on IIQ occurred in 88% of SUI and 69% of MUI.
Conclusion: These new data showing strong objective benefits of the continence dish should be further validated by randomized trials, but this information should be made available to women seeking treatment options for SUI/MUI (particularly in view of concerns regarding mesh mid-urethral slings).
