Introduction: Triple immunohistochemical (IHC) stains including antibodies specific for alphamethylacyl-CoA-racemase and basal cell markers have been a valuable aid in accurate identification of prostate carcinoma. However, accurate quantification of minuscule areas of prostate carcinoma in biopsy specimens can often be a challenge. Here we assessed the diagnostic value and quantitative use of ...

OBJECTIVES To examine the usefulness of an absorbable hemostatic gelatin sponge for hemostasis after transrectal prostate needle biopsy. SUBJECTS AND METHODS The subjects comprised 278 participants who underwent transrectal prostate needle biopsy. They were randomly allocated to the gelatin sponge insertion group (group A: 148 participants) and to the non-insertion group (group B: 130 partici...

BACKGROUND Nowadays, the histological examination of prostate core needle biopsies is still regarded as the gold standard in the diagnosis of prostate cancer (PCa). We investigated if the tissue print of core needle biopsy (biopsy print) could be used as adjunctive molecular investigative procedures in conjunction with routine histological examination of biopsy to improve PCa diagnosis. METHO...

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...

introduction: aim of this study was to assess the association between prostate calcification in transrectalultrasound (trus) and sono- guided needle biopsy in prostate cancer (pca). methods: a cross-sectional study was performed on patients referred to imam khomeini hospital between 2005 and 2011 who underwent trus biopsy due to increased psa or abnormal dre. the serum levels of psa, prostate v...

PURPOSE OF REVIEW To present the recent advances in needle guidance and robotic ultrasound technology which are used for prostate cancer (PCa) diagnosis and management. RECENT FINDINGS Prostate biopsy technology has remained relatively unchanged. Improved needle localization and precision would allow for better management of this common disease. Robotic ultrasound and needle guidance is one s...

UNTIL well into the 1980s, biopsy of the prostate often relied on a few cores using a device such as the Vim-Silverman needle digitally guided transperineally or transrectally into a palpably abnormal prostate. In this pre-prostate specific antigen (PSA) era prostate cancers were often detected at an advanced clinical stage. The modern era of prostate biopsy was ushered in during the late 1980s...

Prostate biopsy and needle-directed prostate therapies are currently performed free-handed or with needle external templates under ultrasound guidance. Direct image-guided intervention robots are modern instruments that have the potential to substantially enhance these procedures. These may increase the accuracy and repeatability with which needles are placed in the gland. The authors' group ha...
