Objective: The use of 10–12-core systemic transrectal ultrasound (TRUS)-guided prostate biopsy protocols with extended-sampling has been an optimizing strategy for diagnosis of prostate cancer. In this study, we aim to examine the cancer detection rate (CDR) and the complications following prostate biopsy at our institution. Materials and Methods: We retrospectively reviewed medical data of patients who underwent TRUS-guided prostate biopsy between 2007 and 2013 at our institution. The pathological outcomes, major complications, and morbidities were recorded and assessed clinically. Results: During the study period, 425 patients who underwent TRUS-guided prostate biopsy were enrolled. The mean age of the participants was 67.9 years. Overall, 75 (17.6%) patients were diagnosed with prostate cancer. Cancer was detected in 0% (0/10), 7.0% (15/215), 16.5% (20/121), and 50.6% (40/79) of patients in the subgroups with patient prostate-specific antigen (PSA) <4 ng/ml, 4–10 ng/ml, 10–20 ng/ml, and >20 ng/ml, respectively. The optimal cutoff values of PSA density were 0.19, 0.29, and 0.78 in the subgroups with patient PSA 4–10 ng/ml, 10–20 ng/ml, and >20 ng/ml. In total, 11 patients had afebrile urinary tract infections (UTI), 9 patients had febrile UTI, and another 2 patients had septic shock after biopsy. The overall incidence of infectious complications was 5.17% (22/425). Other complications were infrequent, consisting only of urinary retention in three patients, hematospermia in two patients, and acute hemorrhagic cerebellar infarction in 1 patient. Conclusion: Our study demonstrated the CDR, the incidence, and type of complications following TRUS-guided prostate biopsy. Further prospective studies are required to determine methods for reducing complications from prostate biopsy.
