Comparative Study
Efficacy and morbidity of transrectal ultrasound-guided 12-core biopsy for detection of prostate cancer in Japanese men.
The objectives of the present study were to determine whether an extensive biopsy scheme contributes to enhanced detection of prostate cancer in Japanese men and to assess the associated pain and morbidity. ⋯ Using this 12-core biopsy scheme, we found cancer most frequently in cores taken at the level of the apex. While the extensive procedure only marginally enhanced overall detection of prostate cancer, it was well tolerated with gradually decreasing pain and morbidity over a brief postbiopsy period. Further efforts to optimize biopsy schemes are warranted.
