MP30-18 ANTIBIOTIC FREE LOCAL ANAESTHETIC TRANSPERINEAL PROSTATE (LATP) BIOPSIES: A REVIEW OF THE FIRST 750 CASES

INTRODUCTION AND OBJECTIVE: A LATP service using PrecisionPoint™ was newly started in July 2019, with procedures performed by both surgeon and nurse practitioners. Initial indications were: repeat biopsy, anterior prostate lesions, and Active Surveillance patients. Service was expanded in March 2020 to all prostate pathway patients according to British Association of Urology COVID guidance. METHODS: All patients underwent prebiopsy MRI and dedicated image-review meetings. Biopsies were performed in PIRADS 3-5, or PSAD>0.15. Systematic Ginsburg protocol biopsies were performed for all patients (each zone sent separately), and PIRADS 3-5 lesions were targeted with ≥3 cores (also sent separately). Alpha-blockers were started for patients with Bladder Outlet Obstruction. No antibiotics were used unless patients were immunocompromised or had a previous history of urinary sepsis. A prospective database at point of care was created detailing patient demographics, MRI and biopsy characteristics. Patient Reported Outcome Measures (PROMs) are collected. Histology and complications are also reported. RESULTS: 750 consecutive patients are analysed. Detection of clinically significant prostate cancer (Gl≥3+4) in PIRADS 1-2, 3, 4, 5 groups was 25%, 40%, 59%, 92% respectively. Systematic biopsy alone detected clinically significant cancer in 36%, whereas systematic plus targeted biopsy achieved 63%. Of Active Surveillance patients;40% with Gl 3+3 were upgraded, and 49% with Gl3+4 were upgraded to Gl≥4+3. n=5 (0.6%) experienced vasovagal episodes causing delayed discharge. Only n=5 patients were readmitted (0.6%): 2 urinary tract infection, 2 acute urinary retention, 1 urinary sepsis. PROMs demonstrated majority favourable results regarding pain (98%), discomfort (97%), embarrassment (96%) and further repeat biopsies (89%). CONCLUSIONS: We have set up a safe, effective, antibiotic free LATP biopsy service, with high cancer detection rates and low complication rates. PROMs data suggests this is well tolerated by patients.
