Relevant markers for overactive bladder laser therapy: nitric oxide and urinary nerve growth factor

Area of Science:

• Urology
• Biomedical Engineering
• Laser Medicine

Background:

• Overactive bladder (OAB) significantly impacts quality of life.
• Current OAB treatments have limitations, necessitating novel therapeutic approaches.
• Identifying reliable biomarkers for treatment response is crucial for personalized OAB management.

Purpose of the Study:

• To evaluate low-level laser therapy (LLLT) for overactive bladder (OAB).
• To assess nitric oxide (NO) and urinary nerve growth factor (NGF) as potential biomarkers for therapeutic outcomes in OAB patients undergoing LLLT.

Main Methods:

• A prospective randomized controlled trial involving 50 OAB patients.
• Application of 650-nm laser irradiation (LLLT).
• Measurement of urinary NO and NGF levels pre- and post-intervention.

Main Results:

• LLLT demonstrated effectiveness in managing OAB symptoms.
• Significant alterations in NO and urinary NGF levels were observed post-LLLT.
• These changes suggest NO and NGF can serve as indicators of therapeutic response.

Conclusions:

• LLLT is a promising treatment for OAB.
• Urinary NO and NGF levels show potential as predictive biomarkers for LLLT efficacy in OAB.
• These biomarkers may aid in optimizing OAB treatment strategies and personalization.
