Standard sextant prostate biopsy may underestimate cancer in men in whom clinical findings are suspicious for localized prostate cancer. We describe our experience with extensive transrectal ultrasound guided prostate biopsy in men in whom previous sextant biopsy was negative.Between November 1997 and March 1999, 57 men 47 to 72 years old (mean age 61.4) underwent extensive transrectal ultrasound guided biopsy of the prostate using intravenous sedation at our institution. An average of 22.5 cores (range 15 to 31) were obtained depending on prostate size. Biopsies were obtained from each of 6 sagittal regions, including samples from the far lateral and mid transitional zones. Each patient had undergone at least 1 previous benign transrectal ultrasound guided sextant biopsy (mean 2.1, range 1 to 4). Indications for repeat biopsy were persistently elevated prostate specific antigen (PSA) in 89
