Effect comparison of two prostate biopsy methods guided by ultrasound

Abstract

Objective To compare the effect between ultrasound guided transrectal prostate biopsy and transperineal prostate biopsy which guided by ultrasound.Methods Totals of 77 patients needed prostate biopsy were randomly divided into two groups,38 cases in transrectal prostate biopsy group and 39 cases in transperineal prostate biopsy group.after operation,gross hematuria,duration of gross hematuria,bloody stool,urinary tract infection,infection,perineum swelling,duration of urine occult blood and comfort level were observed.Results There was no significantly difference about gross hematuria and urinary tract infection ratio in two groups (P＞0.05).The bloody stool and infection of transrectal biopsy group were 13 cases and 10 cases respectively,higher than that in transperineal biopsy group that were 2cases and 4cases,and the difference was statistically significant ( x2 =9.620,8.013 ; P ＜ 0.05 ).The perineum swelling,duration of gross hematuria and urine occult blood in transperineal biopsy group were 6cases,( 26.1 ± 3.6 ) hours,( 9.3 ± 3.7 ) days,higher than 0 case,( 18.3 ± 4.2) hours,(6.6 ± 2.2) days that in transrectal biopsy group,and the difference was statistically significant( x2 =11.236,t =8.075,4.587 ;P ＜ 0.05 ).Comfort of transrectal biopsy group was better than that of transperineal biopsy group(t =9.740,P ＜0.05).Conclusions Transperineal biopsy method is safer than transrectal biopsy method,while the transrectal biopsy method is much more convenient and has a higher comfort level.
