Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Laser

Group Type EXPERIMENTAL

Non-ablative vaginal Erbium YAG laser treatment

Intervention Type 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.

PFE

Group Type ACTIVE_COMPARATOR

Pelvic floor exercises (PFE)

Intervention Type 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.
