Is objective cure of mild undifferentiated incontinence more readily achieved than that of moderate incontinence? Costs and 2-year outcome

A contextual model of pelvic floor muscle defects in female stress urinary incontinence: a rationale for physiotherapy treatment

On the basis of the current literature, we describe a model of structural defects in stress urinary incontinence (SUI) and how physiotherapy for SUI can affect each component of the model with reference to the relevant anatomy and pathophysiology. This model of SUI involves four primary structural defects: (1) increased tonic stress on the pelvic fascia due to pelvic floor muscle (PFM) tears; (2) fascial tearing due to PFM denervation; (3) fascial weakness resulting from tears; and (4) inefficient PFM contraction due to altered motor control. These four components interact to collectively weaken urethral closure and allow urine leakage under conditions of increased intra-abdominal pressure. Physiotherapy can strengthen the PFM and may improve the efficiency and/or timing of PFM contractions to reduce or eliminate SUI. It is worthwhile for motivated women with SUI to try PFM exercise therapy as a first approach to treatment. Women need to be individually instructed to ensure that they correctly perform PFM contractions and that they can monitor their own performance. Long-term, high-intensity exercise, including home exercise, is necessary to achieve maximum effect. Under these conditions the improvement in urinary continence with PFM exercise can be complete and enduring.

The costs and benefits of physiotherapy as first-line treatment for female stress urinary incontinence

OBJECTIVE

To evaluate the costs and benefits of physiotherapy for stress urinary incontinence (SUI) in Australia.

METHODS

We evaluated the costs and benefits of physiotherapy for the treatment of SUI using outcome data from a prospective multicentre observational study conducted in 1999/2000. Women presenting with SUI to physiotherapists trained in continence management in 35 centres across Australia were recruited into the study. The outcomes of treatment were assessed using subjective, objective and quality-of-life measures at the conclusion of treatment and with 12-month follow-up. The number of treatments in an average episode of care was calculated and adverse events were recorded.

RESULTS

Of the 274 consenting subjects, 208 completed an episode of physiotherapy care consisting of a median (IQ range) of five (4-6) visits. The estimated average costs for an episode of ambulatory physiotherapy treatment were dollar 302.40. Based on 'intention to treat' principles, 64% of women were objectively cured. There was a clinically and statistically significant improvement (p < 0.05) in all outcomes after treatment and these were maintained at one-year follow-up. No adverse events were reported.

CONCLUSIONS AND IMPLICATIONS

Specialised ambulatory physiotherapy for SUI in Australia is a low-cost, low-risk and effective treatment. These results provide evidence to support international recommendations that physiotherapy should be routinely implemented as first-line treatment before consideration of surgery. This information has important economic implications for planning future health services.

Incontinence-specific quality of life measures used in trials of treatments for female urinary incontinence: a systematic review

This systematic review examined the use of incontinence-specific quality of life (QOL) measures in clinical trials of female incontinence treatments, and systematically evaluated their quality using a standard checklist. Of 61 trials included in the review, 58 (95.1%) used an incontinence-specific QOL measure. The most commonly used were IIQ (19 papers), I-QoL (12 papers) and UDI (9 papers). Eleven papers (18.0%) used measures which were not referenced or were developed specifically for the study. The eight QOL measures identified had good clinical face validity and measurement properties. We advise researchers to evaluate carefully the needs of their specific study, and select the QOL measure that is most appropriate in terms of validity, utility and relevance, and discourage the development of new measures. Until better evidence is available on the validity and comparability of measures, we recommend that researchers consider using IIQ or I-QOL with or without UDI in trials of incontinence treatments.
