Introduction: Overactive bladder (OAB), a symptom syndrome consisting of urgency, frequency and nocturia, is a common urologic disorder. Percutaneous posterior Tibial Nerve Stimulation (PTNS) is a minimally invasive, well-tolerated and effective treatment of OAB. Recently, Transcutaneous posterior Tibial Nerve Stimulation (TTNS) with surface electrodes has been used, which is entirely non-invasive. The purpose of this study is to examine and compare the efficacy of these two methods of therapy.
Material & Methods: In this randomized clinical trial, 44 patients with OAB were randomly assigned to one of two groups. In both groups (PTNS and TTNS), the therapeutic interventions were performed three times a week for four weeks a total of 12 sessions. Incontinence Quality of Life questionnaire (I-QOL) and Overactive Bladder Symptom Score (OABSS) were evaluated before the intervention, one week and four weeks after completing the sessions.
Results: Of the 44 patients, 41 females and three males, the mean age of the subjects was 51.95 in the PTNS group and 56.86 in the TTNS group (P-value: 0.9). In our study, patients' urinary symptoms and quality of life improved in both groups over time. There was no significant difference between the two interventions (P-value of 0.796 and 0.372, respectively).
Conclusion: Both PTNS and TTNS effectively improved patients' symptoms of OAB and their quality of life. TTNS can be considered as effective as conventional PTNS and be used as a less invasive alternative for PTNS in OAB treatment.
