OBJECTIVE: To investigate the therapeutic effectiveness of trigger point injection into the muscles around the groin in patients with a clinically diagnosed chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).
DESIGN: Prospective, unicenter trial.
SETTING: University rehabilitation hospital.
PARTICIPANTS: Twenty-one cases of suspected myofascial pain syndrome (MPS) in patients with a clinically diagnosed CP/CPPS.
INTERVENTION: Ultrasound-guided trigger point injection.
MAIN OUTCOME MEASURES: Visual analog scale (VAS), National Institutes of Health Chronic Prostatitis Symptom Index score (NIH-CPSI), and injection-associated complication.
RESULTS: Ultrasound (US)-guided trigger point injection on the iliopsoas, hip adductor, and lower abdominal muscles resulted in excellent outcomes. The mean values of the NIH-CPSI decreased significantly from 20.2 at pre-treatment to 12.5 at post-1st treatment (P< 0.05). The mean values of VAS decreased significantly from 6.3 at pre-treatment to 2.9 at post-1st treatment (P< 0.05).
CONCLUSIONS: US-guided trigger point injections on the iliopsoas, hip adductor, and abdominal muscles provide a safe and effective diagnostic and therapeutic means, when the cause of groin pain is suspected to originate from muscles in a patient with CP/CPPS. In particular, the iliopsoas muscle was affected in all patients in this study.
