Effect of non-ablative laser treatment on overactive bladder symptoms, urinary incontinence and sexual function in women with urodynamic stress incontinence

Objective: To investigate the effects of non-ablative laser treatment on overactive bladder (OAB) syndromes, stress urinary incontinence and sexual function in women with urodynamic stress incontinence (USI). Materials and methods: Between April 2015 and June 2015, consecutive patients with USI with OAB syndromes underwent two sessions of Erbium:YAG laser treatment in a tertiary hospital. Patients received validated urological questionnaires, urodynamic studies, 1-h pad test and measurement of vaginal pressure before, one and three months after laser treatment. Questionnaires at 12 months were completed by telephone interview. Adverse effects and patients' satisfaction were also assessed. Results: We included 30 patients with a mean age of 52.6 8.8 years. Three months after therapy, mean 1-h pad test significantly decreased (P = 0.039). Significant improvement in OAB symptoms in four questionnaires were noted at three months post treatment, but not sustained for 12 months in two of them. Three months after therapy, mean vaginal pressure significantly improved (P = 0.009). Of 24 (82.7%) sexually active patients, 62.5% (15/24) and 54.2% (13/24) of their sexual partners reported improved sexual gratification three months later. No major adverse effects were noticed. Conclusions: Erbium:YAG laser treatment can resolve USI and coexistent OAB symptoms three months after therapy. Sexual experience is also improved. However, repeated laser therapy may be necessary after six months. (C) 2017 Taiwan Association of Obstetrics & Gynecology. Publishing services by Elsevier B.V.
