Ultrasound of the urinary tract can demonstrate the exact length of each urethra, looking for stenosis, diverticulations, and anomalies of the periurethral soft tissues as well as associated malformations such as bladder, ureteral duplication, or renal agenesis [1].

Basis of duplex kidney formation by embryology is explained as development of two ureteral buds separately from a single mesonephric duct gives rise to a duplex kidney with complete ureteral duplication.
