[Sacral nerve magnetic stimulation combined with extracorporeal shockwave for the treatment of type-â ¢B chronic prostatitis].

OBJECTIVE: To investigate the clinical therapeutic effects of sacral nerve magnetic stimulation (SNMS) combined with extracorporeal shockwave (ECSW) in the treatment of type-ⅢB chronic prostatitis. METHODS: This study included 65 cases of type-ⅢB chronic prostatitis treated in Renji Hospital between March 2017 and August 2018. The patients were aged 34.56 + 7.47 years and had an average disease course of 12.95 + 10.73 months. We randomly assigned the patients to an experimental (n = 33) and a control group (n = 32) to be treated by SNMS+ECSW and biofeedback combined with electrical stimulation, respectively, qd alt, 40 minutes once, for a total of 24 times. Before and after 4 and 8 weeks of treatment, we obtained the NIH-CPSI scores, maximum urinary flow rate (Qmax), average urinary flow rate (Qavg), Self-Rating Depression Scale (SDS) scores and Self-Rating Anxiety Scale (SAS) scores of the patients, recorded their adverse reactions and compared the clinical therapeutic effects between the two groups of patients. RESULTS: After treatment, the experimental group showed significant improvement in the pain score, urination score, quality of life (QOL) score and NIH-CPSI total scores in comparison with the baseline (P < 0.05), even more significant after 8 than after 4 weeks of treatment (P < 0.05), and in all the indexes as compared with the control group (P < 0.05). Qmax and Qavg were remarkably improved at 8 weeks (P < 0.05) and so were SDS and SAS scores at 4 and 8 weeks (P < 0.05), even more significantly in the experimental than in the control group (P < 0.05). Among the 33 patients in the experimental group, 25 (75.8%) responded (14 ［42.4%］ cured or with excellent effect), with a significantly higher effectiveness rate than the control group (7［46.9%］， P < 0.01). No obvious adverse events were observed in any of the patients during the treatment. CONCLUSIONS: SNMS+ECSW can effectively improve the clinical symptoms and QOL of the patients with type-ⅢB chronic prostatitis, without causing obvious adverse reactions. Its long-term therapeutic effect, however, remains to be further studied.
