title: An unusual ureteric anomaly: uretero-synadelphia with ectopic opening into the urachus.
abstract: An extraordinary case is reported of "uretero-synadelphia" (a single Y-type ureteric tract for both kidneys) with ectopic opening into the bladder vertex. This case also showed an associated agenesis of the extrahepatic biliary ducts. The possible factors in the development of this anomaly are discussed. The term "synadelpho-ureterostomy" is proposed to describe the surgical techniques used to mimic these anomalies, in place of the more commonly accepted "trans-uretero-ureterostomy".
