Sedation may result in reduction in pain during transrectal ultrasound (TRUS)-guided prostate biopsies. We aimed to evaluate the efficacy and safety of a combination of propofol and remifentanil infusion during TRUS-guided prostate biopsy and the related increases in health care costs. From January to September 2010, 100 men undergoing a transrectal prostate biopsy were randomized into two groups. In Group 1, 50 patients received a combined infusion of propofol and remifentanil; in Group 2, 50 patients received lidocaine jelly. After TRUS-guided biopsies were performed, pain and patient satisfaction were evaluated by a 10-point visual analog scale (VAS), and a cost-related patient satisfaction questionnaire was completed by all patients. Patients were also asked whether they would be willing to undergo repeat biopsy by the same method. Patients in Group 1 showed a significantly lower VAS score than those in Group 2 (mean VAS score: 0.9±1.1 versus 6.3±2.5; P<0.001). In addition, the patient satisfaction scale was significantly higher in Group 1 (P=0.002). Although the overall cost was significantly higher in Group 1 (P=0.006), patient satisfaction scales considering cost were also higher in this group (P=0.009). A combination of propofol and remifentanil is a safe and effective way to decrease patient pain and increase patient satisfaction during TRUS-guided prostate biopsy. Although the costs were higher in the group that received sedation, as expected, the patients exhibited heightened satisfaction and willingness to repeat biopsies by the same method.
