[Vaginal laser therapy-myths and facts]

Area of Science:

• Urology
• Gynecology
• Medical Technology

Context:

• The German guideline on Female Urinary Incontinence recommends optional vaginal laser therapy for mild to moderate stress urinary incontinence (SUI).
• The European Association of Urology (EAU) currently lacks a similar recommendation.
• This evaluation critically assesses the scientific evidence supporting the German recommendation.

Purpose:

• To evaluate the scientific evidence for vaginal laser therapy in SUI based on the AWMF guideline.
• To compare the efficacy of Erbium:YAG and CO2 laser systems for mild SUI.
• To identify ideal patient profiles for laser therapy to improve patient selection.

Summary:

• Limited data suggest both Erbium:YAG and CO2 lasers are similarly effective for mild SUI.
• Study comparability is hindered by varying definitions, classifications, and outcome measures.
• An ideal candidate profile includes younger age, normal BMI, adequate estrogenization, pure SUI from urethral hypermobility, and <8g urine loss/hour.

Impact:

• Provides a basis for understanding the current evidence on vaginal laser therapy for SUI.
• Highlights the need for standardized research methodologies in this field.
• Aims to guide appropriate patient selection for laser treatment, potentially improving outcomes and informing future EAU guidelines.
