title: Diagnostic imaging of inverted Y duplication of the ureter with anomalous point angle. A case report.
abstract: A rare anomaly of ureteral duplication is the inverted Y configuration, occurring when 2 distal ureteral limbs fuse proximally to become a single tube draining the kidney. In international literature there is a female predominance. Previous reports documented distal limbs that were atresic or associated with ureterocele or ectopically located. We report a case of inverted Y ureter with an obtuse point angle open caudally; the 2 ureteral limbs reach the bladder trigone and are canalized, even if the supernumerary one is partially stenotic in the distal tract.
