In the 1950s prostate cancer was known to occur in about 20% of men over the age of 55 and was the cause of death in about 5% of white men over the age of 50 (Huggins and Johnson, 1947). It accounted for 90% of all male genital cancers and 63% of male genitourinary cancers and it was believed that 5-10% of prostatic cancers were diagnosed early enough to permit operation with a reasonable chanc...

A 16-year-old German Warmblood mare was presented with an acute history of abdominal pain that failed to respond medical treatment. Diagnostic evaluations including transabdominal and transrectal ultrasound palpation were suggestive a small-intestinal intussusception. Exploratory laparotomy revealed duodenoduodenal intussusception the proximal middle third duodenum. The horse subjected euthanas...

BACKGROUND The objective of this study is to evaluate the diagnostic utility of digital rectal examination (DRE), prostate specific antigen (PSA) and transrectal ultrasonography (TRUS) for prostate cancer. METHODS On 266 patients ultrasonography guided transrectal biopsies were performed using the automatic biopsy gun fitted with an 18 gauge biopsy needle. RESULTS There was no major complic...

Using the fusion of pre-operative MRI and real time intra-procedural transrectal ultrasound (TRUS) to guide prostate biopsy has been shown as a very promising approach to yield better clinical outcome than the routinely performed TRUS only guided biopsy. In several situations of the MRI/TRUS fusion guided biopsy, it is important to know the exact location of the deployed biopsy needle, which is...

BACKGROUND Among different medical image modalities, ultrasound imaging has a very widespread clinical use. But, due to some factors, such as poor image contrast, noise and missing or diffuse boundaries, the ultrasound images are inherently difficult to segment. An important application is estimation of the location and volume of the prostate in transrectal ultrasound (TRUS) images. For this pu...

Ultrasound is a useful modality for the diagnosis of different types of pelvic fractures in horses of many breeds and uses. Ultrasound provides the referral veterinarian and the ambulatory practitioner an alternative to traditional diagnostic modalities (radiography and nuclear scintigraphy). Pelvic fracture should be suspected in horses with acute onset, severe hind limb lameness with or witho...

Endoscopic ultrasound is recommended for rectal cancer staging. Transrectal ultrasound approach is able to overcome one of the limitations of this technique regarding circumferential rectal stenosis. Prior intrarectal administration of a small amount of fluid contrast agent optimizes the method, making it easier to distinguish the layers of the rectal wall and tumor formation. Endoscopic ultras...

BACKGROUND Transrectal ultrasound (TRUS) guided prostate needle biopsy is a commonly used diagnostic procedure. We determined associated risk factors for patients who suffered major complications and required hospitalization after TRUS-guided prostate biopsy. METHODS A total of 1,529 patients, 27 to 92 years old (mean 67.6 years) were included in this study conducted between January 2003 and ...

In 2009, prostate cancer ranked as the most common cancer and the second most fatal cancer in men in the United States. Unfortunately, the current clinical diagnostic methods (e.g. prostate-specific antigen (PSA), digital rectal examination, endorectal MRI, transrectal ultrasound, biopsy) used for detecting and staging prostate cancer are limited. It has been shown that cancerous prostate tissu...

OBJECTIVE Prostate biopsy is a frequent diagnostic measure to detect prostatic conditions, including primarily prostate cancer. Its performance does not follow a pattern, mainly regarding preparation for the examination through antimicrobial prophylaxis. The aim of this study is to compare the efficiency of short and long term antimicrobial prophylaxis in transrectal ultrasound-guided prostate ...
