Purpose:
There were limited studies had been considered that TRUS in prostatitis as a supportive tool. We have noticed that there seemed to present some findings in TRUS with patients being suffered from prostatitis different from normal men, especially in young age. Thus, we tried to determine the role of TRUS in diagnosing prostatitis for the young men
 
Materials and Methods:
From Jan. 2015 to Feb. 2017, all patients younger than 40 years old who underwent TRUS at outpatient department in Taipei City Hospital Zhongxiao Brench were included. Patients with chronic prostatitis history or under antibiotics use for over one week before TRUS examination were excluded. Diagnosis of prostatitis was defined by medical records of history, digital rectal examination (DRE) and antibiotics use. Paravesical hypoechoic findings in TRUS were reviewed by one doctor who did not know the diagnosis of patients before. Size of prostate was measured by TRUS. Data of urine analysis and semen analysis were also collected. Fisher exact test, Mann-Whitney U test and multiple regression analysis were used for statistical analysis.
 
Results:
There were 46 patients younger than 40 years old who were undergoing TRUS from Jan. 2015 to Feb. 2017. Among these patients all were included to our analysis, 29 (63%) had diagnosis of prostatitis. Compared to patients without prostatitis, patient with prostatitis tended to be younger (31.3 versus 34.9, p=0.025). Also, they seemed to have smaller prostate (<20cm), but there was no statistical differences (p=0.092). The hypoechoic findings in TRUS were more probable to be noted in patients with prostatitis (75.9% versus 29.4%, p=0.009). Most of patients were diagnosed with mushy consistency with tenderness of the prostate which were noted during DRE. (93.1%). Hypoechoic findings remained significant after multivariate analysis (p = 0.015).
 
Conclusion:
From this community-based hospital study, we had found the association of paravesical hypoechoic lesions in TRUS and prostatitis. Therefore, we recommended the TRUS as a helpful tool in diagnosing prostatitis in young men.
