PURPOSE To analyze the effects of major pelvic ganglion (MPG) excision on the structure of rat prostate. MATERIALS AND METHODS We studied 80 Sprague-Dawley rats (300-350 gm. weight). Forty-two were anesthetized and the right MPG excised. After 28-30 days, the same-side prostatic ventral lobe (VL) was obtained for macroscopic, light (LM), and transmission(More)
The objective of this paper is to validate prostate specific antigen (PSA) density (PSAD) routine use to enhance PSA specificity in men with normal digital rectal examination and intermediate PSA values. It is a retrospective study of 235 men from a prostate cancer (PCa) screening program. All of them presented PSA values between 4 and 10 ng/ml, normal(More)
Objective: To evaluate the clinical utility of using the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) to quantify prostate-specific antigen (PSA) mRNA in peripheral blood samples from patients with prostate cancer as a predictor of extraprostatic extension of the disease and to assess any correlations with known predictive markers of(More)
OBJECTIVES To document the extent of prostate-specific antigen (PSA)-testing in the general population at Getafe (Spain) outside our prostate cancer (PC) screening program, and to check its performance in terms of PC detection. METHODS A total of 5371 PSA-test records (1997-1999) were reviewed and testing rates estimated per 1000 person-years. The extent(More)
OBJECTIVE To evaluate the overall specificity of nested reverse transcriptase-polymerase chain reaction (RT-PCR) to detect prostate-specific membrane antigen (PSM) mRNA in peripheral blood samples of healthy donors. SUBJECTS AND METHODS Peripheral blood samples were taken from 60 healthy blood-donors (30 men and 30 women aged < 50 years) and analysed for(More)
OBJECTIVE To evaluate the clinical utility of using the reverse transcriptase-polymerase chain reaction (RT-PCR) to detect prostate-specific antigen (PSA) mRNA in peripheral blood samples from patients with prostate cancer, as a predictor of extraprostatic disease, and to assess any correlations with known predictive markers of this condition. PATIENTS(More)
OBJECTIVE To address detection rates and clinical features of the cancers detected with low prostate specific antigen (PSA) levels. METHODS In the context of a prostate cancer (PCa) screening program 1097 men attended to a new rescreen round. Sextant prostate biopsy was recommended when PSA > or =3 ng/ml. We also recommended to undergo biopsy in the range(More)
In this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface conditions: (1) ground, (2) mirror-like polished (reference), and (3) ground plus high-temperature annealed, are investigated. Surface(More)
To demonstrate that percutaneous nephrolithotomy (PCNL) in the Galdakao-modified supine Valdivia position can be safely and effectively reproduced by different surgeons. A multicentre retrospective cross-sectional case study on 317 patients was conducted. The centres enrolled were four hospitals from the Spanish National Health System and provided data for(More)
