Objective To evaluate the long‐term clinical outcome in women with idiopathic detrusor overactivity (IDO) and to identify significant prognostic factors. Design Longitudinal study incorporating retrospective case note review and a postal questionnaire. Setting Tertiary referral urogynaecology clinic in Australia. Population Women with a sole urodynamic diagnosis of IDO. Methods Audit of urodynamic records and case notes. Postal questionnaire incorporating validated disease‐specific quality‐of‐life (QoL) instruments. Main outcome measure Subjective assessment of overall improvement on a 4‐point scale followed by scoring of short forms of the urogenital distress inventory and incontinence impact questionnaire. Results One hundred and thirty two women were identified following examination of 1975 consecutive records with 76 (67%) returning questionnaires. Median follow up was 8 years (6–9), and the duration of symptoms was 13 years (9–18). Improvement was achieved in 25 (35%) women. Disease symptoms fluctuated in severity and QoL were worse in nonresponders to therapy ( P < 0.0001). Urge incontinence at presentation was associated with treatment failure ( P = 0.001) as was nocturia ( P = 0.04), but urodynamic variables were not associated with outcome. Only 3 of 46 (6.5%) women not responding to therapy thought that their symptoms would improve with time. Conclusions IDO seldom resolves and fluctuates in severity. Individual response is unpredictable, although the presence of urge incontinence is associated with a significantly worse prognosis.
