OBJECTIVE: To evaluate the therapeutic efficacy and clinical applicability of the novel P100 extracorporeal shock wave therapy (ESWT) device in the treatment of type IIIB chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).
METHODS: In this randomized, single-blind, sham-controlled trial, 83 patients with type IIIB CP/CPPS were enrolled and randomly assigned to either the P100 treatment group (n = 51) or the control group (n = 32). Patients in the treatment group received four weekly low-intensity ESWT sessions (0.2 mJ/mm²), while the control group received identical procedures with shock transmission blocked. The primary endpoint was the clinical response rate (≥6-point reduction in NIH-CPSI score) at week 4; week 8 outcomes were further analyzed to assess sustained efficacy. Secondary endpoints included IPSS, IIEF-5, and VAS scores.
RESULTS: At week 4, the clinical response rate was 78.4% in the P100 group compared with 25% in the control group (P < 0.001). Median NIH-CPSI scores decreased from 35 at baseline to 13 at week 4 and 12 at week 8, indicating sustained improvement. Significant reductions in PDS, IPSS, and VAS scores were observed as early as week 2 (P < 0.05), and symptom relief remained stable through week 8 without rebound. Exploratory analyses suggest that lower baseline estradiol levels and lower E2/T ratios may be associated with more sustained improvements in erectile function. No treatment-related adverse events were reported.
CONCLUSION: The P100 ESWT device provided rapid, significant, and sustained symptom relief for type IIIB CP/CPPS, particularly in pain and urinary domains. Hormonal balance (E2/T) may influence the long-term maintenance of erectile function after ESWT. These findings support P100 as a safe and effective non-invasive therapeutic option for CP/CPPS, warranting further validation in larger studies with longer-term follow-up.
