PURPOSE We aimed to evaluate the efficacy of magnetic resonance imaging (MRI)-directed cognitive fusion transrectal ultrasonography (TRUS)-guided anterior prostate biopsy for diagnosis of anterior prostate tumors and to illustrate this technique. METHODS A total of 39 patients with previous negative TRUS biopsy, but high clinical suspicion of occult prostate cancer, prospectively underwent pr...

BACKGROUND The objective of this study was to evaluate the efficacy of proton magnetic resonance spectroscopy (1H-MRS) in the detection of prostate cancer. MATERIALS AND METHODS The experimental group consisted of 20 patients with localized prostate cancer who underwent radical prostatectomy. The sensitivity, positive predictive value and accuracy of the detection of prostate cancer in the 12...

BACKGROUND To compare transrectal ultrasound (TRUS)-guided biopsy of the prostate and transurethral resection of the prostate (TURP) for detection of prostate cancer (PCa) in patients with moderate lower urinary tract symptoms (LUTS) by retrospective chart review. METHODS Between January 2004 and December 2008, a total of 520 patients, aged 50.3-81.5 years, with moderate LUTS (International P...

In the early 1990's when systematic biopsy of prostate using transrectal ultrasonography (TRUS) had just begun, there was enthusiasm for identifying abnormalities and obtaining appropriate samples. Since the occurrences of early small prostate cancer are increasing and identifying tumors using TRUS are somewhat subjective, the efficiency of the method in detecting and staging prostate cancer ha...

PURPOSE Traditionally, an interval of 4 to 6 weeks has been recommended after prostate biopsy before open radical prostatectomy. However, such an interval is not explicitly specified in robot-assisted laparoscopic radical prostatectomy (RALP). This study was designed to determine whether the interval from prostate biopsy to RALP affects surgical difficulties. MATERIALS AND METHODS Between Jan...

AIM To evaluate the diagnostic value of the 10 systematic transrectal ultrasound-guided (TRUS) prostate biopsy compared with the sextant biopsy technique for patients with suspected prostate cancer. METHODS One hundred and fifty-two patients with suspected prostate cancer were included in the study. Patients were entered in the study because they presented with high levels of prostate specifi...

What's known on the subject? and What does the study add? Due to the fear of missing clinically significant cancer, it is often uncertain whether a repeat biopsy should be performed in men with ≥ 1 prior negative prostate biopsies but persistent suspicion of prostate cancer. However, the repeat biopsy may again be negative and a biopsy may be associated with anxiety, discomfort and complication...

Infectious complications related to prostate ultrasound and biopsy have increased in the past decade with the emergence of increasing fluoroquinolone bacterial resistance. We investigated the addition of intravenous (iv) piperacillin/tazobactam immediately prior to prostate ultrasound and biopsy with standard fluoroquinolone prophylaxis to determine if it would decrease the incidence of serious...

BACKGROUND Urosepsis is a rare but life-threatening complication following transrectal ultrasound (TRUS) guided needle prostate biopsy. Despite the technological and pharmacological improvements, the problem of bacterial urosepsis after prostate biopsy remains. A strategy for preventing urosepsis following TRUS prostate biopsy in áreas with high prevalence of resistant strains or patients prese...

PURPOSE Prostate cancer foci have a characteristic feature in magnetic resonance imaging (MRI). We aimed to assess the clinical value of MRI before prostate biopsy in prostate cancer detection. MATERIALS AND METHODS From March 2009 to June 2010, 154 patients were enrolled in this study. A total of 51 patients with a clinical suspicion of prostate cancer underwent prostate MRI by a 3T scanner ...
