UROLOGICAL ONCOLOGY Comparison of the Efficacy of Local Anesthesia Methods and Caudal Regional Anesthesia in Prostate Biopsy Applied Under Transrectal Ultrasonography: A Randomized Controlled Study

Results: The pain score during anesthesia induction was significantly higher in the CRA group than in the IRLA and IRLA+PPLA groups (P < 0.001). The pain score during entry of the probe to the rectum and movement was significantly lower in the CRA group than the IRLA groups (P = 0.014). The pain score on penetration of the needle to the prostate and at 30 mins after the biopsy was significantly higher in the IRLA group (P < 0.001). At 2 hours after the biopsy, the pain score in the CRA group was significantly lower than IRLA groups (P = 0.015).
