Design outcomes

Primary

MeasureTime frameDescription
Overactive Bladder questionaire (OAB-q)24 monthsIt consists of an 8 item symptom bother scale section and a 25 item health related quality of life scale section (HRQL). Scores of each domain of the 2 sections range from 0 to 100. Higher scores indicate higher impact of overactive bladder symptoms.
3 days voiding diary24 monthsAssesses bladder function (frequency of micturition, urgency and urinary incontinence)

Secondary

MeasureTime frameDescription
King's Health Questionnaire (KHQ)24 monthsIt has 3 sections: 1) general health and overall health related to urinary symptoms with 2 questions, 2) incontinence impact, role limitations, physical limitations, social limitations, personal limitations, emotions, sleep and energy, and severity coping measures with 19 questions and 3) bother or impact of urinary symptoms with 11 questions. Scores of each domain of the 2 sections range from 0 to 100. Scores of the third section range from 0 to 3. Higher scores indicate higher impact of urinary incontinence.
Patients Global Impression of Improvement (PGI-I)24 monthsIt is a single question with 7 possible answers. Patients will chose the answer that applies at their impression of improvement after the laser therapy
Urogenital Distress Inventory questionaire (UDI-6)24 monthsIt is a 6 item questionaire evaluating symptom distress of urinary incontinence and its impact on daily life. Scores range from 0 to 100. Higher scores indicate higher impact of urinary incontinence.
Pelvic Floor Impact Questionnaire-short form 7 (PFIQ-7)24 monthsIt is a 7 item questionaire evaluating how much bladder symptoms affect their activities, relationships, and feelings.
