background: presence of discordance between the gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. in this study, we determined the accuracy of gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma in our center, which is one...
Prostatic diseases are a common health problem among males in Western countries, and include chronic prostatic diseases, which have an unclear pathogenesis and few treatment options. In vitro and in vivo studies describe oxidative stress as a major pathway involved in the occurrence of benign prostatic hyperplasia, prostatic cancer and chronic prostatitis. Thus, the oxidative stress cascade is ...
The concentration of Lomefloxacin (NY-198), a new quinolone, in human prostatic tissue and fluid was examined. Lomefloxacin was concentrated in prostatic gland and the mean ratios of prostatic tissue levels to serum levels (P/S) were 1.39-1.83 during 2 to 6 hrs after administration. Concerning prostatic fluid concentrations, there were no significant differences between healthy volunteers and p...
Differences in stromal and epithelial cell staining for androgen and glucocorticoid receptors (ARs and GRs) were investigated in 20 patients with clinically localized prostatic carcinoma treated by radical prostatectomy. Sections of benign prostatic hyperplasia and prostatic carcinoma from each patient were stained with antibodies to AR and GR using an avidin-biotin peroxidase technique. The sp...
Prostatic calculi are common and are associated with inflammation of the prostate. Recently, it has been suggested that this inflammation may be associated with prostate carcinogenesis. The aim of this study was to investigate the relationship between prostatic calculi and prostate cancer (PCa) in prostate biopsy specimens. We retrospectively analyzed 417 consecutive patients who underwent tran...
AIM To investigate the risk factors for prostatic inflammation extent and infection in patients with benign prostatic hyperplasia (BPH) so as to manage prostatic inflammation more efficiently. METHODS Sixty patients with BPH undergoing TURP between September 2005 and December 2005 in West China Hospital of Sichuan University were studied. Prostate fluid (PF) was collected for the measurement ...
Using a 0.5 tesla superconducting magnetic system, magnetic resonance imaging (MRI) studies were performed in 42 patients (27 prostatic carcinoma and 15 benign prostatic hyperplasia) and 2 healthy volunteers. Spin echo images were produced in the transverse, coronal and sagittal directions. T1 and T2 relaxation times were calculated from these images. The images of 2 normal prostates showed 2 s...
Magnetic resonance imaging was utilized in 18 patients with prostatic cancer and compared with the findings in normal volunteers (Pontes et al., 1985), benign prostatic hyperplasia (Hricak et al., 1983), acute prostatitis (Walsh and Jewett, 1980) and chronic prostatitis (ACS, 1986). Sixteen of the 18 patients with carcinoma demonstrated inhomogeneous signal intensity, however, a similar appeara...
MLH1 immunoreactivity in prostatic adenocarcinoma. The increased MLH1 expression in the precursor lesion HGPIN suggests a role of MLH1 in prostatic carcinogenesis. However, its expression may not be related to the aggressiveness of prostatic cancer, because the intensity of immunoreactivity is similar in both intermediate and high-grade prostatic adenocarcinoma. Lastly, we have demonstrated the...
ObjectiveTo compare transabdominal (TA) and transrectal (TR) ultrasonography of the prostate gland. DesignExperimental study. Animals10 intact male dogs that required euthanasia for reasons other than prostatic disease. ProceduresProstatic length (L), width (W) and height (H) were measured in T A (L1, W1 and H1) and TR (L2 and H2) ultrasonography. Prostatic volume was calculated using the formu...
