Extensive biopsy using a combined transperineal and transrectal approach to improve prostate cancer detection.

Purpose: Previous studies have indicated that 6-core transrectal prostate biopsy misses a considerable number of cancers. We performed an extensive biopsy protocol of 12-core sampling using both transperineal and transrectal approaches to determine the impact on the cancer detection rate.

Materials And Methods: We prospectively evaluated 402 men who underwent 6-core transperineal and 6-core transrectal biopsies simultaneously due to abnormal digital rectal examination (DRE) and/or elevated prostate-specific antigen (PSA) levels of 4.

[A clinical study of renal pelvic and ureteral cancer: prognosis and frequency of subsequent bladder cancer following surgical treatment].

Purpose: A retrospective investigation of patients presenting with renal pelvic and ureteral cancer was performed. This study focused on the prognostic factors and frequency of subsequent bladder cancer following surgical treatment.

Materials And Methods: Forty-five patients presenting with transitional cell carcinoma, who had undergone nephroureterectomy at the Department of Urology, Okayama Central Hospital, from March 1990 to November 2000, were reviewed.
