Systematic transperineal ultrasound-guided template biopsy of the prostate: Three-year experience

摘要: Abstract Objectives To review the technique of transperineal saturation prostate biopsy and to update our results on patients at high risk cancer. Methods A total 210 men who met study inclusion criteria underwent systematic ultrasound-guided template prostate. All had previously undergone least one set transrectal biopsies 170 (81%) two or more. The mean number cores obtained before was 17.4. 21.2 (range 12 41) were biopsy, depending size. included prostate-specific antigen level 10 ng/mL greater, velocity 0.75 per year presence prostatic intraepithelial neoplasia and/or atypical small cell acinar proliferation previous biopsy. Results Adenocarcinoma detected in 78 (37%). Cancer transition zone 60 (77%) these men, including 36 (46%) whom cancer identified uniquely zone. Gleason sum 6 3 9) most common grade. Thirty radical prostatectomy, 27 (90%) pathologic Stage pT2 disease as final stage. Complications from limited postprocedural urinary retention 11% patients. Conclusions provides uniform sampling entire This appears enhance identification cancers not by adenocarcinoma.
