Use of Non-ablative Vaginal Erbium YAG Laser for the Treatment of Prolapse

Not Applicable
Completed
Conditions
Prolapse
Interventions
Procedure: Non-ablative vaginal Erbium YAG laser treatment
Other: Pelvic floor exercises (PFE)
Registration Number
NCT04523298
Lead Sponsor
Universitaire Ziekenhuizen KU Leuven
Brief Summary

This is a single center, investigator initiated study, sponsored by the UZ Leuven, Leuven, Belgium; comparing laser treatment to pelvic floor exercises (PFE).

Women with symptomatic prolapse (grade II-IV) who seek for a conservative treatment, with no history of previous POP-surgery will be randomised to either the laser-arm or the PFE-arm.

There are 3 visits where vaginal application of laser will be performed, with a 4-weeks interval. Each application lasts around 15 minutes. The vaginal laser procedure will be performed in an outpatient setting, not requiring any specific preparation, analgesia or anesthesia, by one of two experienced operators.

The primary objective is to evaluate the effects of VEL treatment for reduction of prolapse symptoms and as a secondary outcome objective measurements. These endpoints are in line with the recommendations by Durnea et al., as being the most relevant and patient centered outcomes.

The second goals are to register adverse events and to determine for how long the effects of laser are sustained, with a maximum of two years. To do so, the investigators will measure long term satisfaction with, and the longevity of the effect (measured by the need for repeat or alternative therapy) of laser therapy.

Duration of follow-up per patient: max 27 months

Primary Outcome Measures
NameTimeMethod
Primary outcome is the subjective improvement of POP symptoms, assessed by the Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6).6 months after last treatment

Participants have to answer 6 questions concerning POP symptoms with a response scale from 0 to 4 (not present (=0), not at all (=1), somewhat (=2), moderately (=3), quite a bit (=4)). The score (range 0 to 100) is then obtained by multiplying the mean value of all of the answered items by 25. Missing items are dealt with by using the mean from answered items only. Higher scores indicate more distress. This questionnaire is available and validated in English, Dutch and French. Success is defined as a reduction in scores of at least 25% compared with baseline.

Secondary Outcome Measures
NameTimeMethod
Assessment of the rate of patient satisfaction by means of the Patient Global Impression of Improvement (PGI)At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment

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

Assessment of the anatomical success rate by means of the POP-Q systemAt every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment

Anatomical success is defined as POP-Q = grade 0 (no prolapse) or grade I (leading edge \< -1cm)

Assessment of the longevity of the effect of laser therapyAt every visit (ie. week 4, 8 and 12), end of treatment (ie. 4 months after randomisation), 6, 12 and 24 months after end of treatment

Measured by the need for repeating the same, or initiating an alternative therapy

Assessment of the degree of discomfort of the treatment procedure by the patientAt every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment

VAS-score (Visual Analogue Scale: 0-10cm, continuous scale); the higher the score, the higher the discomfort

Assessment of urinary symptoms by means of the Urogenital Distress Inventory (UDI-6)At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment

The final UDI-6 score is calculated by adding all scores as explained in the above, 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.

Assessment of sexual function, by means of the Pelvic Organ prolapse/Urinary Incontinence Sexual Questionnaire IUGA revised (PISQ-IR)At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment

The PISQ-IR is a questionnaire with twenty questions. Q1 is a question to divide the patients based on sexual activity. 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 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 PFD on sexual functioning. This questionnaire is available and validated in English, Dutch and French.
