OBJECTIVE: The objective of this study was to determine the benefit of repeat transrectal ultrasound-guided prostatic biopsy (TRUSBx) among men with prior benign histology on digitally guided biopsy despite suspicious digital rectal examination (DRE) findings.
PATIENTS AND METHODS: From January 1, 1990 to May 30, 1993, we evaluated 130 consecutive men, referred to us with benign pathology on digitally-guided biopsy and DRE suspicious of cancer. All patients underwent systematic and directed TRUSBx.
RESULTS: TRUSBx detected previously undiagnosed malignancy in 67 cases (51%).
CONCLUSION: It is mandatory to reevaluate by TRUSBx, all patients with a palpable abnormality on DRE and a prior benign pathology on digitally-guided biopsy, as the likelihood of finding cancer is elevated.
