To explore the relationship between chronic prostatitis (CP) and prostatic calculus (PC).


We used transperineal ultrasonography (TPUS) to detect PC in 500 normal volunteers and 491 CP patients, and divided them into a CP and a CP + PC group according to the ultrasonographic results. Then we analyzed the NIH-CPSI scores, duration of symptoms and white blood cell count in the expressed prostate secretion (ESP).


PC was found in 19.8% of the normal controls, 5% (5/100), 12% (12/100), 19% (19/100), 27% (27/100) and 36% (36/100) in the 20-30 yr, 31-40 yr, 41-50 yr, 51-60 yr and > 60 yr groups, respectively. In comparison, PC was detected in 42.2% of the CP patients, 15.8% (12/76), 30.1% (69/215), 55.7% (59/109), 66.2% (43/65) and 82.8% (24/29) in the above five age groups, respectively, with statistically significant differences between the control and CP groups (P < 0.01). The CP and CP + PC groups showed significant differences in the duration of symptoms and white blood cell count in ESP (P < 0.01) but not in CPSI scores (P < 0.05).


The incidence of PC is higher in CP patients than in healthy men, and it is associated with inflammation, aging and symptom duration, but not with CPSI scores.
