Low-Energy Shock Wave Therapy for Overactive Bladder in Women With Metabolic Syndrome

30 de abril de 2026 atualizado por: KMUHIRB-F(I)-20230051

A Randomized, Double-Blind, Sham-Controlled Trial of Low-Energy Extracorporeal Shock Wave Therapy for Overactive Bladder in Women With Metabolic Syndrome

Overactive bladder (OAB) is a common condition that causes urinary urgency, frequent urination, and nocturia, which can significantly affect quality of life. Women with metabolic syndrome may have a higher risk of OAB due to vascular and metabolic abnormalities.

This study aims to evaluate the effectiveness and safety of low-energy extracorporeal shock wave therapy (LiESWT), a non-invasive treatment, in women with metabolic syndrome-associated OAB. Participants will be randomly assigned to receive either active LiESWT treatment or a sham (inactive) procedure.

Symptoms and treatment outcomes will be assessed using validated questionnaires, including the Overactive Bladder Symptom Score (OABSS), International Consultation on Incontinence Questionnaire (ICIQ-SF), Urinary Distress Inventory (UDI-6), and Incontinence Impact Questionnaire (IIQ-7), as well as a voiding diary and uroflow measurements.

The results of this study may help determine whether LiESWT is an effective treatment option for improving OAB symptoms in this patient population.

Visão geral do estudo

Descrição detalhada

Overactive bladder (OAB) is a prevalent urological condition characterized by urinary urgency, frequency, and nocturia, which significantly impairs quality of life. Emerging evidence suggests a strong association between OAB and metabolic syndrome, which is characterized by insulin resistance, hypertension, dyslipidemia, and central obesity. These metabolic abnormalities may contribute to endothelial dysfunction, chronic inflammation, and autonomic dysregulation, potentially affecting bladder function.

Low-energy extracorporeal shock wave therapy (LiESWT) is a novel, non-invasive therapeutic modality that has been shown to promote angiogenesis, improve tissue perfusion, and modulate inflammatory responses. Previous studies have demonstrated its potential benefits in various urological conditions.

This study is designed as a randomized, double-blind, sham-controlled trial to evaluate the efficacy and safety of LiESWT in women with metabolic syndrome-associated OAB. Participants are randomly assigned to receive either LiESWT treatment or a sham procedure.

Clinical outcomes are assessed using validated patient-reported outcome measures, including OABSS, ICIQ-SF, UDI-6, and IIQ-7, along with objective parameters such as uroflowmetry and post-void residual volume. Assessments are performed at baseline and at multiple follow-up time points after treatment.

This study aims to provide clinical evidence on the therapeutic role of LiESWT in improving symptoms and quality of life in this specific patient population.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: LiESWT Group
Participants receive low-energy extracorporeal shock wave therapy (LiESWT) applied to the bladder region.
LiESWT is delivered using a focused shock wave device at an energy flux density of 0.25 mJ/mm², frequency of 3 Hz, and 3,000 pulses per session.
Comparador Falso: Sham Control Group
Participants receive a sham procedure that mimics LiESWT without delivering therapeutic energy.
The device is applied in the same manner as the active treatment but does not emit therapeutic shock wave energy.

O que o estudo está medindo?

Medidas de resultados primários

Descrição da medida
Prazo
Change in Overactive Bladder Symptom Score (OABSS)
Prazo: Baseline to 24 weeks
The Overactive Bladder Symptom Score (OABSS; range 0-15, with higher scores indicating more severe symptoms) will be used. The primary outcome is the change in OABSS from baseline to 4, 8, 12, 16, 20, 24 weeks after treatment. Lower scores indicate improvement in symptoms.
