Use of the UPOINT phenotype system in treating Chinese patients with chronic prostatitis/chronic pelvic pain syndrome: a prospective study.
The urinary, psychosocial, organ-specific, infection, neurological/systemic and tenderness (UPOINT) phenotype system has been validated to be an effective phenotype system in classifying patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in western populations. To validate the utility of the UPOINT system and evaluate the effect of multimodal therapy based on the UPOINT system in Chinese patients with CP/CPPS, we performed this study. Chinese patients with CP/CPPS were prospectively offered multimodal therapy using the UPOINT system and re-examined after 6 months. A minimum 6-point drop in National Institutes of Health-Chronic Prostatitis Symptoms Index (NIH-CPSI) was set to be the primary endpoint. Finally, 140 patients were enrolled in the study. The percentage of patients with each domain was 59.3%, 45.0%, 49.3%, 22.1%, 37.9%, and 56.4% for the UPOINT, respectively. The number of positive domains significantly correlated with symptom severity, which is measured by total NIH-CPSI scores (r = 0.796, P< 0.001). Symptom duration was associated with a greater number of positive domains (r = 0.589, P< 0.001). With 6 months follow-up at least, 75.0% (105/140) had at least a 6-point improvement in NIH-CPSI after taking the therapy. All NIH-CPSI scores were significantly improved from original ones: pain 10.14 ± 4.26 to 6.60 ± 3.39, urinary 6.29 ± 2.42 to 3.63 ± 1.52, quality of life 6.56 ± 2.44 to 4.06 ± 1.98, and total 22.99 ± 7.28 to 14.29 ± 5.70 (all P< 0.0001). Our study indicates that the UPOINT system is clinically feasible in classifying Chinese patients with CP/CPPS and directing therapy. [1]References
