METHODS: PubMed, Cochrane and Embase were searched from inception up to May 2021. Sensitivity (Sn), Specificity (Sp), were firstly estimated and subsequently pooled using hierarchical summary receiver operating characteristics (HSROC) modeling for both cut-off ≥3 and ≥4 to predict muscle-invasive bladder cancer (MIBC). Further sensitivity analysis, subgroup analysis and meta-regression were conducted to investigate contribution of moderators to heterogeneity. RESULTS: In total, n=20 studies from 2019 to 2021 with n=2477 patients by n=53 genitourinary radiologists met the inclusion criteria. Pooled weighted Sn and Sp were 0.87 (95%CI: 0.82–0.91) and 0.86 (95%CI: 0.80–0.90) for cut-off ≥3 while 0.78 (95%CI: 0.74–0.81) and 0.94 (95%CI: 0.91–0.96) for cut-off ≥4. The area under the HSROC curve was 0.93 (95%CI: 0.90–0.95) and 0.91 (95%CI: 0.88-0.93) for cut-off ≥3 and ≥4 respectively. Meta-regression analyses showed no influence of clinical characteristics nor cumulative reader’s experience while study design and radiological characteristics were found to influence the estimated outcome. CONCLUSIONS: We demonstrated excellent worldwide diagnostic performance of VI-RADS to determine pre-trans urethral resection of bladder tumor (TURBT) staging. Our findings corroborate wide reliability of VI-RADS accuracy also between different centers with varying experience underling the importance that standardization and reproducibility of VI-RADS may confer to multiparametric magnetic resonance imaging (mpMRI) for preoperative BCa discrimination.
