A medium term analysis of the subjective efficacy of treatment for women with detrusor instability and low bladder compliance

Objective: The aims of this study were to determine the medium term subjective outcome of treatment for women with a urodynamic diagnosis of detrusor instability and low bladder compliance. Setting: A tertiary referral urogynaecology clinic. Participants and methods: One thousand one hundred and five women referred for the investigation of their urinary symptoms were entered into a prospective, long term, quality of life study. Of these, 348 had a videourodynamic diagnosis of detrusor instability or low bladder compliance and form the basis of this paper. Women were contacted by post at least six months following their urodynamic assessment and asked to complete a questionnaire detailing their treatment, its efficacy and side effects, and any residual urinary symptoms. Results: Two hundred and fifty-six women (73.6%) responded to follow up; only 5-5% were cured of their urinary symptoms. The majority (90.2%) had received anticholinergic medication, although only 18.2% continued with this treatment in excess of six months. Many women had residual urinary symptoms following their investigation and treatment. Conclusion: The medium term efficacy of the treatment of detrusor instability and low compliance is disappointing, and a large part of this failure may be attributable to poor treatment efficacy, side effects of medication, or inadequate follow up following the diagnosis and instigation of therapy.
