Female patient presenting with burning micturition since a month. Ultrasound reveals a left sided double ureter but the entire course could not be traced. Hence an IVU was performed.

Patient Data

Age: 30
Gender: Female

Intravenous urography (IVU)

An Intravenous Urography was performed which confirmed the ultrasound diagnosis of a left sided  double ureter. The entire course of the ureters can be traced. The double ureters in this case is of the incomplete/partial variety.

Case Discussion

 

The Committee on Terminology, Nomenclature, and Classification of the Section on Urology of the American Academy of Pediatrics suggests :

  1. Duplex kidney - The duplex kidney has a single renal parenchyma that is drained by two pyelocaliceal systems.

  2. Upper or lower pole - The poles represent one component of a duplex kidney.

  3. Duplex system - The kidney has two pyelocaliceal systems and is associated with a single ureter or with a bifid ureter (a partial duplication) or, in the case of a complete duplication, with 2 ureters (double ureters) that drain separately into the urinary bladder.

  4. Bifid system - Two pyelocaliceal systems join at the ureteropelvic junction (bifid pelvis), or 2 ureters join before draining into the urinary bladder (bifid ureters).

  5. Double ureters - Two ureters open separately into the renal pelvis superiorly and drain separately into the bladder or genital tract.

  6. Upper and lower pole ureters - Upper and lower pole ureters drain a duplex kidney's upper and lower poles, respectively.
