PURPOSE We aimed to identify microbiological characteristics in patients with acute prostatitis after transrectal prostate biopsy to provide guidance in the review of prevention and treatment protocols. MATERIALS AND METHODS A retrospective analysis of medical records was performed in 1,814 cases who underwent prostate biopsy at Seoul St. Mary's Hospital and St. Vincent's Hospital over a 5 ye...

BACKGROUND Granulomatous prostatitis is an uncommon entity that is diagnosed incidentally on histopathology and is broadly classified as nonspecific, specific, postsurgical (post-transurethral resection), or secondary to other rare systemic granulomatous diseases. Only very few studies are available in the literature that describe the clinical and histomorphological spectrum of the disease. M...

PURPOSE Most patients, even some urologists, assume that prostate volume is the most important prognostic factor for lower urinary tract symptoms (LUTS). In some cases, however, prostatic inflammation is a more important factor in LUTS than is prostate volume. For this reason, comparison of the impact on LUTS of inflammation and prostate volume is an attractive issue. MATERIALS AND METHODS Fr...

Transrectal longitudinal ultrasonography was performed in 34 patients with chronic non-bacterial prostatitis. Prostatic stones and cystic lesions were associated with chronic non-bacterial prostatitis in 67.6% and 11.8%, respectively. The annual relapse rates of clinical symptoms were related to the presence of prostatic stones and cystic lesions. Transrectal ultrasonography plays a very import...

BACKGROUND Nonbacterial prostatitis has no established etiology. We hypothesized that proteinase-activated receptor-1 (PAR1) can play a role in prostatitis. We therefore investigated the effects of PAR1 stimulation in the context of a new model of murine nonbacterial prostatitis. METHODS Using a hapten (ethanol-dinitrobenzene sulfonic acid- (DNBS-)) induced prostatitis model with both wild-ty...

Prostatitis ranges from a straightforward clinical entity in its acute form to a complex, debilitating condition when chronic. It is often a source of frustration for the treating physician and patient. There are four classifications of prostatitis: acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain syndrome, and asymptomatic. Diagnosis of acute and chronic bacterial pr...

Prostate-specific antigen (PSA) is now widely accepted as a useful tumor marker for the diagnosis and follow-up of prostatic cancer. An elevated level of PSA has been asserted to be highly specific for prostate cancer, although patients with large benign prostate glands and those with bacterial prostatitis may also have slightly elevated levels. We measured the serum PSA level in the patients w...

We have investigated the significance of leukocytosis1,2) and its prolongation3) in prostatic fluid (PF) from prostatitis patients. In a previous paper we reported an increase in the survival rate of peripheral blood monocytes (PBMC) when cultured with macrophages in PF from nonbacterial prostatitis (NBP) patients, possibly due to cytokines secreted from the macrophages, because elevated interl...

OBJECTIVE To determine the prevalence of prostatitis on histopathological evaluation of prostatic tissue in men without urinary retention. DESIGN, SETTING AND SUBJECTS The clinical data and histopathology reports of men seen from January 1999 through March 2009 at our institution were analysed using Student's t-test, the Mann-Whitney test and Fisher's exact test where appropriate. Values were...
