EFFECT OF 1％ TETRACAINE HYDROCHLORIDE JELLY FOR PAIN CONTROL DURING TRANSRECTAL ULTRASOUND-GUIDED PROSTATE BIOPSY

Objective To study the effects of 1％ tetracaine hydrochloride jelly for pain control of patients receiving transrectal ultrasound (TRUS)-guided prostate biopsy. Methods A total of 100 patients receiving TRUS-guided prostate biopsy were divided into two groups with 50 in each.In Group 1,patients received liquid paraffin,and in Group 2,patients were given 1％ tetracaine hydrochloride jelly before biopsy. Pain score was measured by horizontal visual analogue scales ( VAS ),and pain and discomfort were compared between the two groups. Results The average pain scores at the time of insertion of the ultrasound probe were 2.9 ± 1.7 and 1.4 ± 1.8 ( P =0.000) and the average pain scores at the time of performing biopsy were 5.2±1.5 and 3.1±1.7 (P=0.000) in Group 1 and Group 2,respectively.There were no significant differences between the two groups in terms of age,serum prostate specific antigen,digital rectal examination,TRUS,and biopsy core number ( P ＞ 0.05).There were no significant differences of complications after biopsy,such as hematuria,acute urinary retention,urinary tract infection,rectum bleeding,and fever ( P ＞ 0.05 ). Conclusion TRUS-guided prostate biopsy is safe.Use of 1 ％ tetracaine hydrochloride jelly in the rectum and anus before TRUS-guided prostate biopsy is an effective method for relieving TRUS guided prostate biopsy-induced pain during the procedure.
