BackgroundSedation anesthesia during transrectal ultrasound (TRUS)-guided prostate biopsy is known to decrease patient pain and anxiety, but little is known whether it affects the procedure's prostate cancer detection and complication rates. This study aimed to determine the effect of sedation anesthesia with intravenous (IV) propofol on TRUS-guided prostate biopsy outcomes.MethodsA retrospective analysis of 2,119 patients who underwent TRUS-guided prostate biopsy between November 2009 and February 2019 was undertaken. The patients were divided into two groups: patients who underwent sedation anesthesia with IV propofol and patients who underwent local anesthesia with intrarectal lidocaine gel instillation. Cancer detection and complication rates were compared between the two groups. Univariate and multivariate binary logistic regression and multinomial logistic regression analyses were conducted to investigate the effects of sedation anesthesia with IV propofol on prostate cancer detection and complication rates.ResultsThe cancer detection rate of patients in the sedation group was 34.0%, whereas it was 29.2% in the local group (P = 0.024). Multivariate logistic regression analysis regarding factors associated with cancer detection rate after TRUS-guided prostate biopsy in patients with prostate specific antigen (PSA) < 10 showed that IV propofol usage, age, PSA density and core length were significant factors. Multivariate logistic regression analysis regarding factors associated with complications (voiding dysfunction, bleeding and infection) showed that IV propofol usage, age and prostate size were significant factors for voiding dysfunction.ConclusionSedation anesthesia with IV propofol during TRUS-guided prostate biopsy was associated with a higher cancer detection rate than local anesthesia with intrarectal lidocaine gel instillation. Cancer detection rate could be an important factor to consider when selecting for the optimal anesthesia for TRUS-guided prostate biopsy.© 2022 The Korean Academy of Medical Sciences.
