Objective• To describe a protocol for transperineal sector biopsies (TPSB) of the prostate and present the clinical experience of this technique in a UK population. Patients and Methods• A retrospective review of a single-centre experience of TPSB approach was undertaken that preferentially, but not exclusively, targeted the peripheral zone of the prostate with 24-38 cores using a 'sector plan' . Procedures were carried out under general anaesthetic in most patients.• Between January 2007 and August 2011, 634 consecutive patients underwent TPSB for the following indications: prior negative transrectal biopsy (TRB; 174 men); primary biopsy in men at risk of sepsis (153); further evaluation after low-risk disease diagnosed based on a 12-core TRB (307). Results• Prostate cancer was found in 36% of men after a negative TRB; 17% of these had disease solely in anterior sectors.• As a primary diagnostic strategy, prostate cancer was diagnosed in 54% of men (median PSA level was 7.4 ng/mL).• Of men with Gleason 3+3 disease on TRB, 29%were upgraded and went on to have radical treatment.• Postoperative urinary retention occurred in 11 (1.7%) men, two secondary to clots. Per-urethral bleeding requiring hospital stay occurred in two men. There were no cases of urosepsis. Conclusions• TPSB of the prostate has a role in defining disease previously missed or under-diagnosed by TRB. The procedure has low morbidity.
