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

| Non-ablative vaginal Erbium YAG laser treatment | Procedure | There are 3 visits where vaginal application of laser will be performed, with a 4-weeks interval. If needed, 3 extra laser applications can be added to the treatment (ie. with a maximum of 6 applications). 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. Laser therapy is performed using a 2940 nm VEL (SP Spectro, Fotona, Slovenia(24)) with SMOOTH mode setting, which enables non-ablative, thermal-only operation(25). The parameters are selected based on extensive preclinical and clinical studies(26,27,28). Each laser treatment session consists of a full vaginal canal irradiation (using a 360° circular adapter), followed by additional irradiation of the prolapsed anterior wall (using a 90° angular adaptor) and concluded with irradiation of the vestibule area. |

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

| Assessment of the anatomical success rate by means of the POP-Q system | Anatomical success is defined as POP-Q = grade 0 (no prolapse) or grade I (leading edge < -1cm) | At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment |
| Assessment of the rate of patient satisfaction by means of the Patient Global Impression of Improvement (PGI) |

| Pelvic floor exercises (PFE) | Other | Standard PFE in Belgium are 9 sessions with a pelvic floor physiotherapist of choice, which can be extended by another 9 sessions, if clinically indicated. There are different strategies, though that will be on discretion of the physiotherapist. We will register the type of physiotherapy (standard (PFMT) versus assisted pelvic floor muscles training (APFMT)), number of completed sessions and duration of therapy. What is exactly done by the patient is registered as a variable. |

| At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment |
| Assessment of the degree of discomfort of the treatment procedure by the patient | VAS-score (Visual Analogue Scale: 0-10cm, continuous scale); the higher the score, the higher the discomfort | At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment |
| Assessment of the longevity of the effect of laser therapy | Measured by the need for repeating the same, or initiating an alternative therapy | At 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 |
| Assessment of sexual function, 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 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. | At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment |
| Assessment of urinary symptoms by means of the Urogenital Distress Inventory (UDI-6) | 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. | At every visit (ie. week 4, 8 and 12, optional: 16, 20 and 24 weeks), 6, 12 and 24 months after end of treatment |
