Application Analysis of UPOINT System in Chinese Type III Prostatitis Patients: A Single Center Experience.

UPOINT clinical phenotype system was used to estimate the type III prostatitis patients. Put in the erectile dysfunction (ED) domain and analysis the ED domain's effect towards the UPOINT system.

A total of 126 patients with type III prostatitis were prospectively collected and classified in each domain of the UPOINT system, including urinary, psychosocial, organ-specific, infection, neurological/systemic, and tenderness. Symptom severity was measured using the national institutes of health chronic prostatitis symptom index (NIH-CPSI) and the international prostate symptom score (IPSS). The erectile function was evaluated using the international index of erectile function (IIEF-5). Mental state was evaluated using the Symptom Checklist 90 (SCL-90). The quality of life of patients was assessed by the Quality of Life scale (QoL).

The percentage of patients positive for each domain was 60.32%, 43.65%, 53.17%, 11.11%, 42.06%, and 33.33% for the urinary, psychosocial, organ-specific, infection, neurological/systemic, and tenderness, respectively. There were significant correlations between the number of positive UPOINT domains and total NIH-CPSI (r = 0.630, P < 0.001) and IPSS (r = 0.429, P < 0.001). Symptom duration was associated with a number of positive domains (r = 0.194, P < 0.05). After adding an ED domain to establish a modified UPOINT system, the correlation between the number of positive domains and symptom severity was not improved (0.630 to 0.590, P < 0.001). The percentage of the patients who suffered psychosocial problems was 43.65%.

In our cohort, the number of positive domains was correlated with symptom severity. Inclusion of the ED phenotype in the UPOINT phenotype classification system did not significantly enhance the association of positive presentation with symptom severity. Our findings presented do not support the utility of using ED as a stand-alone item in the UPOINT domain. Psychological problems should be considered when treating type III prostatitis patients.
