Purpose
To assess the effect of transcutaneous electrical nerve stimulation (TENS) for treating refractory overactive bladder syndrome (OAB).
Patients and methods
A consecutive series of 42 patients treated with TENS for refractory OAB was prospectively investigated at an academic tertiary referral centre. Effects were evaluated using bladder diary for at least 48 h and satisfaction assessment at baseline, after 12 weeks of TENS treatment, and at the last known follow-up. Adverse events related to TENS were also assessed.
Results
Mean age of the 42 patients (25 women, 17 men) was 48 years (range, 18–76). TENS was successful following 12 weeks of treatment in 21 (50 %) patients, and the positive effect was sustained during a mean follow-up of 21 months (range, 6–83 months) in 18 patients. Following 12 weeks of TENS treatment, mean number of voids per 24 h decreased significantly from 15 to 11 (p < 0.001) and mean voided volume increased significantly from 160 to 230 mL (p < 0.001). In addition, TENS completely restored continence in 7 (39 %) of the 18 incontinent patients. Before TENS, all 42 patients were dissatisfied or very dissatisfied; following 12 weeks of TENS treatment, 21 (50 %) patients felt satisfied or very satisfied (p < 0.001). No adverse events related to TENS were noted.
Conclusions
TENS seems to be an effective and safe treatment for refractory OAB warranting randomized, placebo-controlled trials.
