Objective: To present two-dimensional/three-dimensional (2D/3D) SlowflowHD features of the fetal duplex kidney. Case description: Two fetal unilateral duplex kidneys at 30 and 32+3 weeks were identified between February 2023 and January 2024. Lengths of both kidneys were >95th percentile of the reference ranges of the normal fetal kidney. Two separate noncommunicating renal pelvises (RP) were evident by 2D sonography and HDlive silhouette. 2D/3D SlowflowHD clearly showed perihilar renal arterial branching and characteristic bridge vessels between the upper renal moiety and lower kidney. Conclusion: SlowflowHD may provide novel and unique vascular information on fetal renal anomalies such as the duplex kidney.
