Obstructing calculus in a single limb of a duplicated ureter: A Recall of the surgical anatomy and the Variable Ureter Anomalies

The ureter is a common site of congenital anomalies which may be associated with a considerable morbidity particularly among young patient. The congenital anomalies of the ureter coexist with multitude of other urinary tract anomalies but it may occur independently. It is more common in females. The complete duplication of the ureter may not produce symptoms which would suggest the presence of malformation. Therefore, such anomaly may not become apparent until later in life. Further, this anomaly might not be recognized prior to the surgery and hence, missing of the stone is highly possible. Herein we present a case of complete ureter duplicate with an obstructive stone located close to VUJ of one limb of the duplicate. A sound knowledge of the surgical anatomy and of the congenital ureter anomalies is essential for correct diagnosis and appropriate management.
