PURPOSE: We determined overactive bladder symptoms in combination with other lower urinary tract symptoms and illustrated their relationships using a statistical analysis. Furthermore, we also describe the potential contributory factors and adaptation strategies in patients that are associated with overactive bladder subtypes. MATERIALS AND METHODS: A total of 1,930 women with a mean age +/- SD of 46 +/- 15 years (range 15 to 91) with troubling lower urinary tract symptoms were successfully interviewed with a validated questionnaire at the urology and urogynecology clinics at 14 medical centers in Taiwan. The questionnaire was constructed to evaluate 6 lower urinary tract symptoms and 7 adaptation strategies. A log linear statistical model and multiple logistic regression analysis were used to assess the associations among lower urinary tract symptoms and the potential overactive bladder contributory factors, respectively. RESULTS: No single or isolated symptom presented in patients with overactive bladder. Most patients reported a combination with other lower urinary tract symptoms. These female patients can be categorized into 3 groups, including 1 is associated with dry symptoms (urgency, frequency and nocturia), 1 associated with wet symptoms (urgency, urge incontinence and mixed stress incontinence) and a small group that may have overactive bladder symptoms combined with voiding difficulty symptoms. in contrast to patients with dry overactive bladder (urgency associated with frequency and/or nocturia without urge incontinence), after multiple logistic regression analysis patients with wet overactive bladder (urgency with urge incontinence) had a greater average age and higher body mass index, and made more adaptation efforts (p <0.05). CONCLUSIONS: We used statistical analysis to determine and suggest that urgency is the core symptom of female overactive bladder syndrome and there are 3 distinctive overactive bladder subtypes, which differ in their symptom combinations. Different symptom combinations and patient characteristics affect female adaptation to overactive bladder syndrome.
