Abstract
BACKGROUND: To determine the efficacy and safety of a periprostatic nerve block combined with perineum subcutaneous anaesthesia and intrarectal lidocaine gel for transrectal ultrasound-guided transperineal prostate biopsy (TPBx) through a prospective randomised controlled trial. METHODS: In total, 216 patients from May 2018 to November 2018 were randomly assigned to the experimental group and the control group at a ratio of 1:1. The experimental group received a periprostatic nerve block combined with subcutaneous perineal anaesthesia and intrarectal lidocaine gel. The control group received total intravenous anaesthesia. A visual analogue scale (VAS) score (0-10) was used to evaluate pain at different stages. The operative time, duration of hospitalisation, intraoperative vital signs, perioperative complications and clinicopathological features were recorded. RESULTS: The overall detection rate of prostate cancer was 40.74%, and the median Gleason score was 8 for all patients diagnosed with prostate cancer. No significant differences in terms of detection rates, Gleason scores and ISUP/WHO Grade Groups were found between the two groups (P > 0.05). The experimental group had no pain or just met the criteria for mild pain during the biopsy, which was significantly alleviated after the biopsy, and had a shorter operation time compared with that of the control group (P < 0.05). Compared with the control group, the experimental group had more stable haemodynamics and respiratory status and fewer surgical complications (P < 0.05). CONCLUSIONS: In multiple aspects, a periprostatic nerve block combined with subcutaneous perineal anaesthesia and intrarectal lidocaine gel is a safer and more efficient approach to local anaesthesia for TPBx that can almost replace total intravenous anaesthesia and is worthwhile applying in the clinical setting.
