Description
Summary:Objectives: To report the outcome in the yield of two techniques of prostate biopsy. Patients and methods: The study was a retrospective review of the experience with digitally guided trans-rectal Tru-cut needle biopsy of the prostate using manually- driven and the Biopty gun-driven methods. The record of patients who had undergone prostate biopsy was retrospectively reviewed from January 2000 to December 2007. Data extracted included the age, the year of biopsy and/or the method of biopsy, the status of the operator and the histology report of tissue obtained. Data was analysed with the aid of SPSS (Version 11.0) software, the Chi - square test was calculated for the variables and statistical significant P value at P < 0.05. Results: A total of 292 prostate biopsies were undertaken during the review period. One hundred and ninety were gun-driven (65.1%) while 34.9% were manually-driven. A total of 55.5% of the specimens were benign prostate hyperplasia while 28.4% were adenocarcinoma of the prostate on histological examination. Thirty-six per cent of the tissues obtained from manually-driven biopsy were not representative as compared with only 4% of tissue from gun-driven biopsies. There was a significant correlation between the method of biopsy and the likelihood of tissue representativeness for histological appraisal (P<0.0001). Conclusion: There was a significant difference in the tissue yield between manually- driven and the gun-driven Tru-cut needle biopsy of the prostate.. Biopty-driven Tru- cut needle sampling of the prostate is the recommended procedure in this environment.
