Background: The 2017 AUA White Paper on prevention of prostate needle biopsy (PNB) complications highlights an algorithm for reducing procedural related infections. The incorporation of topical rectal antiseptic (TRS) at time of transrectal PNB is listed as one such modality. We present data on over 1000 transrectal PNB procedures to determine the impact of TRS on 1) infectious complications and 2) use of augmented procedural antibiotics., Methods: The records of 1181 transrectal PNB procedures performed over a 10-year period were reviewed. In 2013, TRS with either 10% povidone iodine or 4% chlorhexidine was more regularly incorporated into PNB procedures. Clinical and procedural factors were analyzed for association with post-procedure infections. Infectious complications outcomes were compared in patients receiving TRS (n = 566) versus those who had not (n = 615)., Results: A total of 990 men underwent 1181 transrectal PNB procedures. Median age of the cohort was 63 years with a median PSA of 7 ng/dL. Of them, 86% of the men were Caucasian, 28% had undergone at least one prior biopsy, 14% were diabetic, and 6% had prior hospitalization within 6 months of the procedure. Five hundred sixty-six patients (48%) received TRS at time of biopsy. Perioperative IV adjunctive antibiotics were used less frequently in patients receiving TRS (13.4% vs. 28.6%, p < 0.001). Furthermore, patients receiving TRS experienced lower rates of clinical infections (1.2% vs. 2.4%, p = 0.14), as well as lower likelihood of severe infections evidenced by decreased rates of hospital admission (0.5% vs. 2.3%, p = 0.013). Rectal vault bacteriology obtained before and after TRS was available in 180 men noting a 98.1% decrease in colony counts after local treatment., Conclusions: TRS at time of transrectal PNB was associated with decreased use of IV procedural antibiotics as well as decreased severity of infections post-biopsy. This simple technique enhances antibiotic stewardship while simultaneously improving quality outcomes of the procedure., Competing Interests: None., (© 2021 Asian Pacific Prostate Society.

Background: To evaluate early consequences of 2012 United States Preventive Services Task Force (USPSTF) recommendations for decreased prostate-specific antigen (PSA) screening on prostate biopsy characteristics and prostate cancer presentation., Materials and Methods: A single tertiary-care institution, multisurgeon, prospectively maintained database was queried for patients undergoing prostate biopsy from October 2005 to September 2016. Patient demographics, biopsy characteristics, and extent of disease were reported. Patient cohorts before and after USPSTF recommendations were compared using two-sample t test, Chi-square test, and Wilcoxon rank sum test with significance at P  < 0.05., Results: A total of 2,000 patients were analyzed, including 1,440 patients before and 560 patients after USPSTF recommendations. Following the recommendations, patients had higher prebiopsy PSA (5.90 vs. 6.70, P  < 0.001). Overall, 817 (40.9%) patients had prostate cancer detected at biopsy with an increase from 37.0% before to 50.8% after ( P  < 0.001). Biopsies detected less low-risk Gleason ≤6 prostate cancer (47.4% vs. 41.1%) and more intermediate-risk Gleason 7 cancer (30.9% vs. 39.7%), with comparable findings of high-risk Gleason ≥8 cancer (21.7% vs. 19.2%), P  = 0.042. In addition, greater percentage of core involvement ( P  < 0.001) was seen. At the time of diagnosis, extraprostatic extension identified by pelvic imaging increased from 12.6% to 18.9%, P  = 0.039, with a trend toward lymph node positivity (1.1% vs. 2.2%, P  = 0.078). Of those with metastatic disease, bony involvement occurred more often (1.7% vs. 3.2%, P  = 0.041)., Conclusions: After 2012 USPSTF guidelines, patients presented with higher PSA with prostate cancer were detected more frequently. More adverse, pathologic prostate cancer features were found on biopsy with the extent of disease implicating locally advanced/metastatic disease. These findings should be considered when counseling patients about prostate cancer screening importance.
