Magnetic resonance imaging (MRI) has deeply altered the prostate biopsy strategy to detect prostate cancer. However, it is still debatable whether the detection rate differs between transrectal (TR) and transperineal (TP) MRI-targeted biopsy (MRI-TB). To compare the effectiveness of these two methods for detecting both overall prostate cancer (PCa) and clinically significant PCa (csPCa), We performed a review and meta-analysis.Until January 2023, we conducted a thorough search of Cochrane, Embase, Ovid, and PubMed. In total, 1482 references were identified, and 15 records were finally included. For PCa and csPCa discovered by TP and TR MRI-TB, we combined the relative sensitivity (RR) with 95% confidence intervals (CI). The RR between the TP and TR routes was established.Our study included 8826 patients in total and revealed that TP MRI-TB detected more PCa (RR 1.25 [95% CI 1.12, 1.39], p < 0.0001). In patients who underwent TP MRI-TB and TR MRI-TB at the same time or separately, TP MRI-TB had a greater detection rate of csPCa in per-patient analysis (one cohort (RR 1.33 [95% CI 1.09, 1.63], p = 0.005); two cohorts (RR 1.37 [95% CI 1.16, 1.61], p  = 0.0002)). However, the detection rate of csPCa between the TP route and the TR route was comparable in per-lesion analysis (RR 0.91 [95% CI 0.76, 1.08], p  = 0.28). Additionally, in the prostate's anterior region, we found that TP MRI-TB detected more csPCa (per-lesion (RR 1.52 [95% CI 1.04, 2.23], p  = 0.03); per-patient (RR 2.55 [95% CI 1.56, 4.16], p  = 0.0002)).According to this comprehensive study, TP MRI-TB is more effective than TR MRI-TB at detecting PCa and csPCa. Significant results persisted for detecting csPCa located in the anterior zone. The results need to be taken carefully notwithstanding the heterogeneity among the included studies.© 2023.
