Use of Non-ablative Vaginal Erbium YAG Laser for the Treatment of Stress Urinary Incontinence.

The tool used is the UDI-6 questionnaire. Converted UDI-6 scores range between 0 and 300. The "minimum important difference" is defined as a (MID)=11. In that score, cure is defined as answering "No" (0) to the question "Do you experience urine leakage related to physical activity, coughing or sneezing?".

The final UDI-6 score is calculated by adding all scores, and dividing the result to 6 to obtain a mean value which is in turn multiplied by 25 to obtain the scale score. The score varies from 0 to 100. The basic interpretation of the score is that the higher the score, the higher the disability . This questionnaire is available and validated in English , Dutch and French .

A working group of the International Continence Society (ICS) has developed instructions on the performance, interpretation and reporting of the CST in a standardized manner: the ICS-Uniform Cough Stress Test (ICS-UCST).

For the ICS-UCST it is recommended that the patient is in a supine/lithotomy position with 200-400 mL of fluid in the bladder, which can be non-invasively assessed with a bladder scan. She coughs forcefully 1-4 times and the examiner directly visualizes the urethral meatus for the presence of leakage. Leakage of fluid from the urethral meatus coincident with/ simultaneous to the cough(s) is considered a positive test. If the test is negative (i.e, no leakage detected), then accessory stress testing such as repeating the test in the upright position should be considered.

5-point Likert scale (1=much worse, 2=worse, 3=same, 4=better, 5=much better)

VAS-score (0-10cm, continuous scale)

measured by the need for, and the timing for repeating the same, or initiating an alternative therapy.

by means of the Pelvic Organ prolapse/Urinary Incontinence Sexual Questionnaire IUGA revised (PISQ-IR). The PISQ-IR is a questionnaire with twenty questions. Q1 is a dividing question on being sexually active or not. Not sexually active (NSA) women are referred to Q2-Q6. Sexually active (SA) women are asked to fill out Q7-Q20. The questionnaire for NSA women consists of five questions or 12 items. A higher score refers to a higher impact of the PFD on sexual functioning. The questionnaire for SA women consists of 14 questions wherein women with a partner have to fill out all 14, being 22 items. Women without partner can skip questions 13 and 14, filling out 19 items. A lower score refers to a lower impact of the PFD on sexual functioning. This questionnaire is available and validated in English, Dutch and French .

Therefore we will monitor how many of the participants attended the PFE treatment complete all sessions with their physical therapist.
