Plain English summary of protocol

Background and study aims
Pelvic floor dysfunction is a common condition in women that can cause symptoms such as a feeling of vaginal bulging, discomfort, and sexual difficulties. Many women want treatments that work but are not invasive. This study looks at whether a gentle laser treatment called non-ablative Er:YAG laser can improve the structure and function of the vagina in the short term. We are interested in whether the treatment can reduce the size of the vaginal opening, change vaginal length, or improve sexual function.

Who can participate?
Women diagnosed with pelvic floor dysfunction who meet the study’s eligibility criteria.

What does the study involve?
Participants receive one to three laser treatment sessions. Measurements and questionnaires are completed before treatment, about 6–8 weeks after the first session, and again 6–8 weeks after the second session. We check changes in vaginal measurements, pelvic organ support, and sexual function, and monitor for any side effects.

What are the possible benefits and risks of participating?
The treatment may improve symptoms related to pelvic floor dysfunction, but this is not guaranteed. There may be mild side effects, which will be monitored during the study.

Ethics approval(s)

Approved 24/01/2024, Ramon Llull University Ethics Committee -FCSB (Padilla, 326-332, Barcelona, 08025, Spain; +34 932533256; bsalutcer@blanquerna.url.edu), ref: 2024/01/01

Health condition(s) or problem(s) studiedPelvic floor dysfunction
InterventionThe intervention consisted of IncontiLase® and IntimaLase® protocols delivered with the SP DYNAMIS system (S/N 14003339), aiming for controlled mucosal heating to approximately 65 °C to promote tissue tightening and collagen remodeling. Two sessions were administered 6–8 weeks apart by experienced operators; analgesia was provided as needed, eye protection and antiseptic preparation were used, and standard post-procedure instructions were given. The total pulse energy delivered to the anterior wall, posterior wall, 360° region, and vulvar region was recorded per session. Safety was assessed clinically at each treatment and follow-up visit; transient post-procedural sensations (local warmth, mild stinging, watery discharge, transient vulvovaginal erythema/edema) were recorded separately from adverse events (persistent pain, dysuria, vaginal spotting, irritation, or vaginal/urinary tract infection).
Intervention typeProcedure/Surgery
Primary outcome measure(s)

At baseline (prior to the first laser session), follow-up 1 (6–8 weeks after the first session), follow-up 2 (6–8 weeks after the second session):
1. The vaginal hiatus was assessed following the criteria set forth by the joint report of the International Continence Society and the International Urogynecological Association (ICS/IUGA) on terminology for female pelvic floor dysfunction
2. Total vaginal length was defined as the distance in centimeters from the posterior fornix to the hymen, with point C or D reduced to its normal position.

Key secondary outcome measure(s)

At baseline (prior to the first laser session), follow-up 1 (6–8 weeks after the first session), follow-up 2 (6–8 weeks after the second session):
1. Pelvic floor muscle strength was assessed by vaginal palpation using the Oxford scale
2. Sexual function was evaluated with the self-administered Female Sexual Function Index (FSFI), which assesses six domains (desire, arousal, lubrication, orgasm, satisfaction, pain)
