The necessity of routine prostate biopsy prior to transurethral resection of the prostate (TURP) in elderly comorbid patients with a high prostate specific antigen (PSA) level remains controversial. We assessed the role of TURP in prostate cancer diagnosis in these individuals. A total of 197 patients underwent TURP in conjunction with prostatic needle biopsy. Pathologic reviews of specimens of...

We present a case of primary mucinous adenocarcinoma of the prostate. A 55-year-old male with no previous history of malignancy presented to our hospital with difficult defecation and anus distention; on magnetic resonance imaging scan of the pelvis, we found a prostate tumor. A transrectal ultrasound-guided needle biopsy confirmed the diagnosis. The patient underwent radical prostatectomy. Pri...

Introduction/Background With serum prostate specific antigen (PSA) screening, clinical stage T1c prostate cancer (defined as nonpalpable prostate cancer diagnosed by needle biopsy only, frequently due to an elevated PSA) has become the most commonly diagnosed prostate cancer. However, clinical stage T1c cancers are a heterogenous group, consisting of both clinically insignificant cancers, and c...

BACKGROUND Focal targeted therapy has been proposed as a potential treatment for localized prostate cancer in an attempt to reduce morbidity. However, these modalities rely heavily on accurate tumor localization to achieve total tumor ablation. In the current study, we sought to examine the ability of contemporary extended pattern prostate biopsy to predict the location of tumors. METHODS A t...

This paper presents a methodology of creating a statistical atlas of spatial distribution of prostate cancer from a large patient cohort, and uses it for designing optimal needle biopsy strategies. In order to remove inter-individual morphological variability and determine the true variability in cancer position, an adaptive-focus deformable model (AFDM) is used to register and normalize prosta...

Background. A parallel manipulator concept using bistable polymer actuators has been developed to perform prostate cancer biopsy and deliver therapy within the bore of a Magnetic Resonance Imaging (MRI) scanner. The dielectric elastomer actuators (DEA) used in this manipulator concept are promising for MRI-compatible robotics because they do not interfere with the high magnetic fields of MRI wh...

Genitourinary tuberculosis is a common type of extra-pulmonary tuberculosis . The kidneys, ureter, bladder or genital organs are usually involved. Tuberculosis of the prostate has mainly been described in immune-compromised patients. However, it can exceptionally be found as an isolated lesion in immune-competent patients. Tuberculosis of the prostate may be difficult to differentiate from carc...

Introduction Since MR-guided interventions require both high image quality and short acquisition times, in clinical routine such procedures are increasingly performed within closed-bore high field MR systems which offer only limited patient access. Safe and precise localization of the instruments is mandatory for any intervention. Recently, an automatic tracking technique has been presented, wh...

In this paper, a novel concept for phantom of the prostate is introduced. To study and improve automated, robotized medical interventions, reliable phantoms are essential. During brachytherapy biopsy, will undergo displacements changes in orientation due to needle insertion. Therefore, there shift target regions radioactive seed deposition or biopsy acquisition. These shifts need be taken into ...

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...
