Objective 1: To advance the investigators understanding on the effect of solifenacin succinate (10 mg OD) vs. fesoterodine (8mg OD) on urinary urgency using a validated Urgency Severity and Impact Questionnaire (USIQ).

Hypothesis 1.1: The severity of urgency symptoms as measured by USIQ will change differently in women with OAB following a 3 month treatment with solifenacin succinate (10 mg OD) vs. fesoterodine (8mg OD).

Hypothesis 2.1: Condition-specific quality of life (QOL) as measured by USIQ will change differently in women with OAB following a 3 month treatment with solifenacin succinate (10 mg OD) vs. fesoterodine (8mg OD).

Objective 2: To advance the investigators understanding on the adverse events (AE's) of solifenacin succinate (10 mg OD) vs. fesoterodine (8mg OD).

Hypothesis 1.1: The severity and rate of AE's in women with OAB following a 3 month of treatment with solifenacin succinate (10 mg OD) vs. fesoterodine (8mg OD) will be different.

Primary Outcome Measures:
  • Changes in urgency sensation [ Time Frame: two months following treatment ]
    The effect of two different antochloinergic treatment on urgency symptoms will be measured by comparing USIQ scores changes in the two study arms, before and after treatment. Changes in urgency sensation will be analysed by subsiding the USIQ scopre at 2 months (second visit) from the USIQ score at baseline. Independent student t- test will be used for Comparison between the changes in USIQ score of the two groups.

Secondary Outcome Measures:
  • Adverse events [ Time Frame: two months ]
    Tolerability of both drugs will be monitored throughout the study based on reported AEs and discontinuations.

Detailed Description:
The National Overactive Bladder Evaluation (NOBLE) Program estimated the prevalence of OAB in the US is nearly 17% affecting approximately 30 million adults. Sixty-one percent of adults with OAB also have urge urinary incontinence (UUI. Urinary urgency is a key symptom of OAB. Urgency may be more bothersome to patients than urinary frequency, although urinary frequency is often the primary focus of study in the field of OAB. This may be partially due to controversy surrounding how to define the term 'urinary urgency'. As currently defined, urgency is meant to describe an abnormal sensation that is distinguishable from the normal feeling of "urge to void," which occurs during a normal bladder-filling cycle. Attempts to measure urgency are confounded by difficulties in understanding this definition in the context of a normal "urge" to void. This controversy probably arises because of the overlap of the English words 'urge' and 'urgency' during clinical conversation, and apparently does not give rise to confusion in other languages. Recently a new validated questionnaire for the measurement of urgency symptoms was validated[5, 6]. The USIQ consists of two parts with an initial filter question, designated for self-administration. The first 5 items, known as USIQ- severity (USIQ-S), inquires about urgency symptoms and severity, while the second part USIQ- quality of life (USIQ-QOL) consists of 8 questions which inquire about bother and condition specific QOL such as: cooping behaviors, work, commuting and travel, sleep, physical activities, social activities, psychological well-being, relationships and sexual function. Items for each scale are summed and transformed to a score ranging from 0-100. Higher symptom bother scores indicate increasing symptom bother, and higher USIQ-QOL scores indicate worse health related quality of life. The main objective of this current study is to compare the effect of two different anticholinergic medications on symptoms of urinary urgency using a validated, subjective instruments designed specifically for this purpose.
