Transcutaneous tibial nerve stimulation to treat urgency urinary incontinence in older women: 12-month follow-up of a randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: Urgency urinary incontinence (UUI) is highly prevalent in elderly individuals and has a great impact on quality of life. Transcutaneous tibial nerve stimulation (TTNS) can be an effective treatment option for UUI in older women. METHODS: This is a single-center randomized clinical trial with a 12-month follow-up involving 106 women > 60 years of age. Kegel exercises and bladder retraining were performed alone or in combination with TTNS, which consisted of using a transcutaneous electrical nerve stimulator for 30 min once a week for 12 weeks with the following settings: continuous mode, 10 Hz, 200 ms, and 10 to 50 mA (according to hallux mobilization). Responders to therapy who experienced failure during follow-up were invited for a 3-week protocol with the same parameters as those used for the initial therapy. Patients were evaluated at baseline, 4 weeks after the 12-week protocol, and every 3 months for 12 months, through subjective satisfaction questionnaires, a 3-day bladder diary and the International Consultation on Incontinence Questionnaire-Short Form. King's Health Questionnaire was applied pretreatment and 4 weeks after the last session of the 12-week protocol. RESULTS: A total of 101 women completed the initial 12-week protocol. TTNS patients reported 66.7% subjective global satisfaction vs. 32.0% in the control group (p < 0.001). The TTNS group showed statistically significant improvement in quality of life (QoL) and UUI parameters compared with the control group. Forty-eight patients were satisfied after the 12-week protocol and completed the 12-month follow-up (32 in the TTNS group and 16 in the control group). A total of 80.5% of responders to TTNS were still satisfied at the end of the 12-month follow-up vs. 30.8% in the control group (p = 0.009). CONCLUSION: TTNS is effective at the 12-month follow-up for the treatment of UUI in elderly women.

Randomized trial of transcutaneous tibial nerve stimulation to treat urge urinary incontinence in older women.

INTRODUCTION: The aim of this study was to examine the efficacy of transcutaneous electrical tibial nerve stimulation (TTNS) to treat urge urinary incontinence (UUI) in older women. MATERIAL AND METHODS: The study design was a randomized clinical trial conducted on 51 elderly women (>60 years) with UUI. All were treated with 12 weeks of bladder retraining and pelvic floor muscle exercises, and 25 were randomly selected to receive TTNS in addition to the standard therapy. The cases were evaluated at the baseline and after the end of therapy by 3-day bladder diary, quality of life questionnaires (QoL), and subjective response. RESULTS: Of the patients, 68.0% in TTNS group reported cure or improvement vs. 34.6% in the control group (P = 0.017). TTNS showed significant improvement in most areas of QoL and in UUI parameters when compared with the control group. CONCLUSION: TTNS is efficacious to treat UUI in older women.
