Transperineal versus transrectal ultrasound-guided prostate biopsy in detection of clinically significant and insignificant prostate cancer:A prospective randomized controlled trial
Objective:To compare transperineal prostate biopsy(TPB)with transrectal ultrasound-guided prostate biopsy(TRUSB)in detection of clinically significant prostate cancer(csPCa)and insignificant PCa(insPCa).Methods:We conducted a prospective randomized clinical study on 279 patients receiving TPB(n=144)or TRUSB(n=135)from January 2022 to January 2023,and compared the detection rates of csPCa and insPCa between the two groups.Results:The detection rate of PCa was signifi-cantly higher in the TPB than in the TRUSB group(37.50％vs 28.15％,P=0.026).There were no statistically significant differ-ences between the TPB and TRUSB groups in the detection rates of insPCa(6.94％[n=10]vs 4.45％[n=6],P＞0.05)and csPCa(30.56％[n=44]vs 23.70％[n=32],P＞0.05),nor in the detection rate of csPCa between different groups of age,PSA concentration and prostate volume(P＞0.05).No statistically significant differences were observed between the TPB and TRUSB groups either in the positive rate of biopsy punctures([16.44±2.86]％vs[12.48±2.39]％,P＞0.05)or in the bi-opsy-related complications of urinary retention,urinary tract infection,hematuria and rectal bleeding(P＞0.05).Conclusion:TPB is more effective than TRUSB in detection of PCa,but there is no statistically significant difference between the two approaches in the detection rates of csPCa and insPCa.
