Abstract

Purpose: We prospectively observed a possible benefit from urethro-anal high frequency electrostimulation in patients with noninflammatory chronic pelvic pain syndrome (Cat IIIB CPPS) as a new treatment option.

Materials and methods: A total of 88 patients with a referral diagnosis of chronic prostatitis underwent fractionated urinary cultures, including expressed prostate secretion and ejaculate analysis twice. Of this group 14 men with Cat IIIB CPPS elected electrostimulation. A urethro-anal stimulation device was applied twice weekly for 30 minutes during 5 weeks at a defined voltage of 6 V, a defined frequency of between 450 and 500 Hz, and a variable self-regulated current of between 1 and 10 mA. National Institutes of Health prostatitis symptom score and quality of life index were determined before and after the treatment.

Results: All patients tolerated stimulation and completed the treatment course. No urethral or anal complications occurred. Generally, the patients reported a distinct perineal feeling and the pain syndrome improved in 83%. The mean total National Institutes of Health prostatitis symptom score significantly decreased from 29 (range 20 to 37) to 14 (range 8 to 24) points (p = 0.002). Mean pain decreased from 15 (range 12 to 20) to 7 (range 4 to 13) points (p = 0.002). Micturition complaints decreased from 2.5 (range 0 to 9) to 1 (range 0 to 8) points (p = 0.007) and quality of life improved from 9.5 (range 8 to 12) to 5.5 (range 3 to 10) (p = 0.003).

Conclusions: To date the new high frequency urethro-anal afferent electrostimulation device seems to have an important benefit in patients with Cat IIIB CPPS. The device is technically simple and it can be self-administered. Therefore, it may become a new ambulatory treatment option for patients with chronic pelvic pain syndrome.
