Objective:
To study the relationship of the content of prostatic exosomal protein (PSEP) in the urine with the counts of WBCs and small particles of lecithin (SPL) in the EPS and NIH-CPSI in patients with chronic prostatitis.
Methods:
We collected mid-stream urine samples from 367 chronic prostatitis patients in the Department of Andrology of the General Hospital of Eastern Theater Command from November 2017 to August 2018. We measured the content of PSEP in the urine, counted WBCs and SPLs in the EPS of the patients, obtained their NIH-CPSI scores, and analyzed the correlation of the PSEP level with the WBC and SPL counts and NIH-CPSI scores of the patients.
Results:
The PSEP level in the urine was elevated with the increase of the WBC count in the EPS of the patients (r = 0.19, P = 0.047) but not significantly correlated with the SPL count in the EPS (r = 0.02, P = 0.48). A significant correlation was observed between the PSEP level and the NIH-CPSI scores of the patients (r = 0.31, P = 0.02).
Conclusions:
The PSEP content in the urine can be used as an indicator in the clinical diagnosis and assessment of the inflammation degree of chronic prostatitis.
