Objectives: To prospectively evaluate sacral magnetic high-frequency stimulation as a treatment option for patients with non-inflammatory chronic pelvic pain syndrome (CPPS, category IIIB).
Patients and methods: Fourteen men with CPPS IIIB were treated with high-frequency sacral magnetic stimulation, with 10 treatment sessions once a week for 30 min at a frequency of 50 Hz. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and quality-of-life index were determined before and after treatment.
Results: All patients tolerated the stimulation well and 12 of 14 reported agreeable sensations during stimulation. There were no complications; only one patient did not complete the treatment course. The mean (range) total NIH-CPSI score did not change with treatment, at 27 (18-38) before and 27 (4-40) after treatment. Moreover, there was no sustained effect on the mean scores for pain, micturition complaints or quality of life.
Conclusions: High-frequency sacral magnetic stimulation in patients with CPPS IIIB only reduces pain during stimulation, with no sustained relief of symptoms. Therefore, intermittent sacral magnetic stimulation cannot be recommended as a treatment option for CPPS IIIB.
