Natural history of non-neurogenic overactive bladder and urinary incontinence over 5 years in community-dwelling older men: The concord health and aging in men project.

Abstract

To describe the natural history of non-neurogenic overactive bladder (OAB) and urgency incontinence in community-dwelling older men. A representative sample of 1,705 community-dwelling men aged 70 and older in a defined geographic area of Sydney, Australia, had their urinary symptoms assessed using the International Prostate Symptom Scores (IPSS) and the International Consultation of Incontinence Questionnaire (ICIQ) at baseline, 2-year follow-up, and 5-year follow-up. Four hundred and eighty-eight men without neurological diseases or prostate cancer during follow-up, or history of urological treatment at baseline were included in the analysis. Urgency incontinence was defined as leakage of urine occurring more than weekly in the above-defined population. OAB was defined as either urgency or urgency incontinence according to 2002 International Continence Society consensus. Of the men with OAB at baseline, 29% received treatment for OAB or benign prostatic enlargement over 5 years. Of the remaining men, 33% had sustained remission at 2-year and 5-year follow-ups without treatment. Of the men with OAB at 2-year follow-up, remission rate at 5-year follow-up was 53% in men without OAB at baseline and 27% in men with OAB at baseline (P = 0.23). No statistically significant difference was found in baseline characteristics between men with sustained remission and men with persistent symptoms. One in three older men with non-neurogenic OAB had sustained remission of symptoms without medical or surgical interventions. No significant predictor of sustained remission was identified.
