We were able to obtain satisfactory postoperative PSA levels by RTUR-PCa comparable with open radical prostatectomy. But we recently started to think that, after a considerable number of the procedures, minimal residual prostate tissue at the part where cancer was not detected by biopsy might not necessarily prevent the radicality of the disease in carefully selected patients. We performed prostate biopsy to get information about the localization of cancer. The results of cancer localization from operative specimens were consistent with those from biopsy specimens in
