RESUMEN
<p><b>OBJECTIVE</b>To investigate the effect of the combination therapy of biofeedback with electrical stimulation on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) through clinical trials.</p><p><b>METHODS</b>A total of 140 cases of diagnosed CP/CPPS were randomly divided into a control group (n = 20), a biofeedback group (BF, n = 40), an electrical stimulation group (ES, n = 40), and a biofeedback plus electrical stimulation group (BF + ES, n = 40). The latter three groups were treated by corresponding methods 5 times a week for 2 weeks, while the controls left untreated. After the treatment, all the patients were followed up for 30 days. The NIH chronic prostatitis symptom index (NIH-CPSI) scores and the results of uroflowmetry were obtained and compared before and after the treatment.</p><p><b>RESULTS</b>Compared with the control group, the scores on pain, urinary symptoms and quality of life (QOL) and the total NIH-CPSI scores were obviously decreased (P < 0.05), and the maximum flow rate (MFR) markedly improved (P < 0.05) in the BF, ES and BF + ES groups after the treatment, with significant differences between the former two and the latter one (P < 0.05), but not between the BF and ES groups (P > 0.05), nor in the control group before and after the treatment (P > 0.05).</p><p><b>CONCLUSION</b>The combination therapy of biofeedback with electrical stimulation has a synergistic effect on CP/CPPS by alleviating pain and urinary symptoms, improving QOL and elevating MFR.</p>
