The difference between bacterial prostatitis and aseptic prostate is the following: 1. The causative factors of both are different. The causative factors of bacterial prostatitis are retrograde infection of the urethra to the prostate and the onset of the disease, mainly seen in patients treated by transurethral operations, such as catheterization, transurethral cystoscopy, transurethral resection of the prostate, and patients treated by surgery for stones and tumors of the transurethral urinary system. The actual aseptic prostatitis is mostly chronic onset, with a long course, individual patients even more than 0.5-1 years.
