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...

We compared electrophoretic evaluation of acid phosphatase isoenzymes with spectrophotometric determination of prostatic acid phosphatase in terms of clinical utility. In all of 33 cases of prostatic carcinoma, an increased prostatic fraction was detected; in nine prostatectomized patients, this fraction returned to normal as measured by either technique. Abnormal spectrophotometric results wer...

AIMS Small cell prostatic cancer is a rare but aggressive disease. Currently, its histogenetic origin is unclear and its distinction from metastatic small cell lung cancer is challenging. The aim of our study was to determine whether the ERG rearrangement commonly observed in acinar prostatic cancer can distinguish small cell prostatic cancer from small cell lung cancer samples. METHODS AND R...
