[Ureteral triplication]
Introduction:
Ureteral triplication is considered a rare anomaly and its association with ectopic ureterocele, is unusual.
Clinical Case:
We report a male with a history of recurrent urinary tract infections, who showed left vesicoureteral reflux associated with apparent ureteral duplication in multiple test performed, and only during the vesicostomy was discovered a third ureter ending in a ectopic ureterocele corresponding with the upper pole ectopic kidney.
Conclusions:
Being a very unusual and complex pathology, and despite all the tests made, it is very difficult to make an accurate presurgical diagnosis, therefore the diagnosis sometimes is only performed during the surgical treatment, which must be individualized according to fthe unctional stage of each renal portion and the termination of each ureter.
