BACKGROUND The histologic grade of a prostate needle-core biopsy specimen can determine whether a patient with prostate cancer is a candidate for radical prostatectomy or other treatment. Incorrect histologic grading can result in inappropriate treatment and possible liability. Thus, we conducted this study to determine the histologic-grading accuracy of prostate cancer needle-core biopsy speci...

Objectives: To determine the factors that predict failure of systematic prostate biopsy by examining clinical, laboratory, and radiological parameters patients for whom cancer was detected magnetic resonance imaging (MRI)-targeted but not biopsy. Methods: Patients were included in this study if they had undergone combined targeted They biopsy-naive lesions with a Prostate Imaging Reporting Data...

OBJECTIVE We wanted to assess the relationship between pain and the prostate volume during transrectal ultrasound (TRUS) guided biopsy. MATERIALS AND METHODS Between July and September 2006, 71 patients scheduled for TRUS biopsy of the prostate were considered for inclusion to this study. These patients underwent periprostatic neurovascular bundle block with lidocaine prior to biopsy. Pain wa...

Early prostate cancers are best detected with transrectal ultrasound (TRUS)-guided core biopsy of the prostate. Due to increased longevity and improved prostate cancer screening, more men are now subjected to TRUS-guided biopsy. To improve the detection rate of early prostate cancer, the current trend is to increase the number of cores obtained. The significant pain associated with the biopsy p...

This paper discusses the virtual prostate needle biopsy system and the construction of the virtual prostate model, considering the actual distribution of prostate abnormalities. A needle biopsy simulation is performed for the constructed virtual prostate, and the actual biopsy procedure in the clinical situation is evaluated. The prostate needle biopsy is a histologic diagnosis procedure in whi...

PURPOSE When faced with biochemical recurrence after definitive radiotherapy for prostate cancer, clinicians must determine whether the recurrence is local or systemic. Post radiotherapy prostate biopsies to detect persistent local disease are difficult to interpret histopathologically and are subject to sampling error. Our study examines outcomes for patients with a negative prostate biopsy pe...
