objective: various practical methods have been used for pregnancy diagnosis in sheep. methods of pregnancy diagnosis depending on visualization of the conceptus or determination of its secretory products in the maternal blood or in the milk are the most accurate and specific methods for pregnancy. in 1980, b-mode ultrasonography was introduced in the veterinary field and used for pregnancy diag...

CONTEXT AND OBJECTIVE Prostate cancer is a major public health issue. Its incidence is rising, especially in Nigeria. Prompt diagnosis is necessary by histology. Transperineal and transrectal approaches to prostate biopsy are well-documented. Both methods are fraught with complications though, most times minor. Studies carried out to compare both methods were carried out mainly on Caucasians, g...

PURPOSE To assess the diagnostic value of an initial 24-sample transrectal ultrasound guided (TRUS) prostate biopsy protocol compared to the 10-core technique. MATERIALS AND METHODS We retrospectively reviewed the prostate biopsy database of consecutive men undergoing prostate biopsies under local anesthesia by using the 10 (Group A) and 24 (Group B) protocols. Men were stratified according t...

INTRODUCTION The objective of this study was to evaluate the correlation of suprapubic ultrasonography and transrectal ultrasonography in measurements of prostate dimension and volume. MATERIALS AND METHODS One hundred consecutive patients with lower urinary tract symptoms were examined by suprapubic and transrectal ultrasonography modalities in a same session. Measurements of the 3 dimension...

Infection due to prostate biopsy afflicted more than 5% of patients and is the most common reason for hospitalization. A large series from US SEER-Medicare reported that men undergoing biopsy were 2.26 times more likely to be hospitalized for infectious complications within 30 days compared with randomly selected controls. The factors predicting a higher susceptibility to infection remain large...

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...

Transrectal ultrasonography (US)-guided biopsy is the standard approach for histopathologic diagnosis of prostate cancer. However, this technique has multiple limitations owing to the operator's inability in most cases to directly visualize and target prostate lesions. Magnetic resonance (MR) imaging of the prostate overcomes many of these limitations by directly depicting areas of abnormality ...

The main objective of this study was to evaluate the effects of transrectal guidance of the ovaries by an assistant on operative time during bovine laparoscopic ovariectomy. Twenty four clinically healthy Holstein dairy cows were divided randomly into two groups. In the transrectal guidance group, an assistant grasped the ovaries via the transrectal route and pulled them to a position where the...
