Abstract

Purpose: Assessment effectiveness of local anesthesia by periprostatic block in transrectal ultrasound guided prostatic biopsy. Material and Methods: This prospective study was conducted on 68 patients who were suspected of having prostate cancer with clinically and subclinically requiring a biopsy for definitive diagnosis at the National Cancer Hospital from August 2022 to July 2023. In transrectal ultrasound guided, the patient is given local anesthesia by periprostatic block then systematic prostate biosy and evaluates the pain immediately according to the Visual Analogue Scale (VAS - from 0 to 10) with levels ranging from no pain to worst pain. Summarize all VAS and pain levels to evaluate the effectiveness of local anesthesia method. Results: 68 patients have mean age is 72 years old, with urine delivery difficulties accounting about 76,47%; digial rectal examination found abnormal in 70,58% of patients. The men of total PSA level are of 40,16ng/ml with the mean of prostate volume is 55g. After local anesthesia by periprostatic block and systematic prostate biopsy, patients who have feeling no pain (VAS 0), accounting for 42,64%; mild pain accounts for 55,88%, of which VAS 1 is 30,88% and VAS 2 is 25%, moderate pain with VAS 3 is only 1,48%. Conclusion: Local anesthesia by periprostatic block in transrectal ultrasound guided prostatic biopsy is highly effective, safe, easy to access and perform.
