Prostate Biopsies Guided by Three-Dimensional Real-Time (4-D) Transrectal Ultrasonography on a Phantom: Comparative Study versus Two-Dimensional Transrectal Ultrasound-Guided Biopsies

Prostate biopsies guided by three-dimensional real-time (4-D) transrectal ultrasonography on a phantom: comparative study versus two-dimensional transrectal ultrasound-guided biopsies

OBJECTIVE This study evaluated the accuracy in localisation and distribution of real-time three-dimensional (4-D) ultrasound-guided biopsies on a prostate phantom. METHODS A prostate phantom was created. A three-dimensional real-time ultrasound system with a 5.9MHz probe was used, making it possible to see several reconstructed orthogonal viewing planes in real time. Fourteen operators perfor...

[Transrectal ultrasound guided biopsies in 266 patients].

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...

Complications and risk factors in transrectal ultrasound-guided prostate biopsies.

CONTEXT AND OBJECTIVE Prostate biopsy is not a procedure without risk. There is concern about major complications and which antibiotics are best for routine use before these biopsies. The objective was to determine the rate of complications and the possible risk factors in prostate biopsies. DESIGN AND SETTING Prospective study, Faculdade de Medicina de Botucatu. METHODS Transrectal ultraso...

Factors Influencing the Acceptance of Transrectal Ultrasound-Guided Prostate Biopsies

PURPOSE This study aimed to improve prostate biopsy compliance by analyzing the factors that influence the acceptance of prostate biopsy by patients to whom transrectal ultrasound (TRUS)-guided prostate biopsy is recommended for suspected prostate cancer. MATERIALS AND METHODS The subjects of this study were 268 patients to whom TRUS-guided prostate biopsy was recommended from January to June...
