Trans-rectal ultrasound guided biopsy of the prostate: nationwide diversity in practice and training in the United Kingdom

Abstract

Introduction: TRUS-guided needle biopsy of the prostate is the standard technique in the diagnosis of prostate cancer. However the practice is highly variable across the United Kingdom. We survey the standard approaches to TRUS biopsy of prostate, highlighting the nationwide diversity of practice and training.

Methods: One hundred and eighty questionnaires were sent out to specialist registrars, investigating the number of prostate biopsy cores taken, the use of prophylactic antibiotics, rectal preparation and local analgesia in TRUS biopsy of the prostate. One hundred and fourteen trainees (63%) returned the questionnaires. Twenty-three percent reported sextant biopsy as standard, 36% taking eight-core and 26% taking 10 or more cores. There is no standard regime for antibiotic prophylaxis. Eighteen percent also reported rectal preparation as routine. Thirty-eight percent of the patients receive local anaesthesia prior to the biopsy. Overall, 42% of the TRUS biopsies are carried out by urologists, 29% by radiologists and 21% by both. Six percents have nurse practitioners' involvement. Fifty-six percent of trainees are involve in the TRUS biopsy, 68% do not think they received enough training to carry out the procedure.

Conclusions: TRUS-guided needle biopsy of the prostate is the standard technique in the diagnosis of prostate cancer. Our survey highlights nationwide diversity in practice in the UK with respect of the number of cores taken, antibiotic prophylaxis and local anaesthesia utilisation. This raised the issue of standardising the practice. More urologists are also actively taking part in this procedure, making the structured training increasingly important.
