PURPOSE: Stress urinary incontinence (SUI) and mixed urinary incontinence (MUI) lead to poor quality of life. In Japan, urinary incontinence is treated with tension-free vaginal tape (TVT) or transobturator tape (TOT) sling procedures, which involves inserting a synthetic material; however, problems arise with artificial mesh in some instances, requiring new treatment methods. Hence, laser therapy, whereby an erbium-doped yttrium aluminum garnet laser is directed into the vagina and urethra, may be useful. The study aimed to compare the effects of these three treatments.
METHODS: Subjects included patients who received TVT, TOT, or laser therapy (n = 50 each). The 1-h pad test, International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and overactive bladder symptom score were used to assess the patients before and 12 months after treatment. For laser therapy, a probe was inserted into the vagina after applying a local anesthetic to the vaginal wall, and irradiation was performed for 20 min at a wavelength of 2940 nm. This treatment was performed three times every alternate month.
RESULTS: As per the 1-h pad test and ICIQ-SF, the TVT, TOT, and laser therapy groups showed comparable improvements in SUI. For patients with MUI, some in the TVT and TOT groups showed exacerbation; however, all patients in the laser therapy group tended to improve.
CONCLUSIONS: The efficacy of laser therapy for urinary incontinence was confirmed. This is the first study to report on the effect of laser therapy on urinary incontinence in Japanese women.
