In the risk estimation tests, Urinoma and ureteral duplication were the only variables associated with an increased risk of ureteral stenosis (Table 4).
The factors that we found for an increased risk of US were perioperative urinoma (OR 3.2, CI95% 2.36-4.37) and ureteral duplication (UD) (OR 3.29 CI95% 2.40-4.51).

Duplex system can be described as the kidney with two pyelocaliceal systems, with either single ureter or bifid ureter (partial ureteral duplication) or double ureter draining separately into the urinary bladder (complete ureteral duplication).[sup.1,2] The incidence of duplex renal collecting system and ureter ranges from 0.5 to 3.0%.[sup.3,4] Complete ureteral duplication is more rarely seen compared to single ureter or partial duplication.
To the best of our knowledge, this the first case report of a patient with unilateral complete ureteral duplication and ureteral stone without coexisting complications, including collecting system obstruction, VUR and/or ureterocele.
Throughout the embryonic development, 2 ureteral buds rarely develop separately from a single mesonephric duct, giving rise to a duplex kidney with ureteral duplication.[sup.2,5] Unilateral complete ureteral duplication with a single renal parenchyma drained by 2 pyelocaliceal systems is even more rare.[sup.2] Urinary stone formation is a possible comorbidity which can be observed in patients with duplex system.[sup.2,5] Few reports include patients with duplex systems and urinary stones with coexisting ureterocele and/or collecting system obstruction.[sup.2,3,5] To the best of our knowledge, this is the first case with unilateral complete ureteral duplication and ureteral stone without coexisting comorbidities including VUR, ureterocele and obstructive uropathy.
