ABSTRACT
<p><b>OBJECTIVE</b>To compare the detection rates of prostate cancer (PCa) and complications of the transrectal ultrasonography (TRUS)-guided 24-core saturation scheme versus 14-core scheme for transperineal prostate biopsy in patients with total PSA < 20 microg/L.</p><p><b>METHODS</b>We performed TRUS-guided 24-core saturation transperineal biopsy for 136 patients suspected of PCa (24-core group) and 14-core biopsy for another 116 (14-core group). We compared the PCa detection rates and post-biopsy complications, such as gross hematuria, urinary system infection, and acute urinary retention between the two groups.</p><p><b>RESULTS</b>The baseline characteristics of the two groups were comparable with regard to the mean age, prostate volume and PSA level (P>0.05). The positive rates of PCa detection were 48.53% (66/136) in the 24-core group and 17.24% (20/116) in the 14-core group (P<0.001), and the positive rates of samples were 8.09% and 2.83%, respectively (P=0.012). The detection rate of PCa in the apex zone was significantly higher in the former (11.76%) than in the latter (1.72%) (P<0.05). There were no statistically significant differences in such post-biopsy complications as gross hematuria, urinary system infection, and acute urinary retention between the two groups (P>0.05).</p><p><b>CONCLUSION</b>TRUS-guided 24-core saturation transperineal biopsy of the prostate is superior to the 14-core scheme for its higher detection rate of PCa, particularly PCa in the apex zone, and lower incidence of complications in patients with PSA < 20 microg/L.</p>
