[Triple ureter with inverted ureteral branch in "y" with ectopic ending and calculi inside].

OBJECTIVE

To report an uncommon case of ureteral duplication with a single intramural trajectory and a third ureter arising from the medial ureter, corresponding to the inferior pyelon, opening at the level of the bladder neck and containing a calculus measuring 10 mm along its longest axis, lodged in a saccular dilatation. The etiopathogenesis of this rare anomaly is briefly reviewed and discussed.

METHODS/

RESULTS

Diagnosis was established endoscopically and pyelographically. Endoscopic resolution was not possible, but stone removal was successfully achieved by conventional surgery using the least invasive approach possible. The patient is asymptomatic 24 months postoperatively.

CONCLUSION

Although infrequent, this condition should be suspected in those "unclear' cases seen in day-to-day urological practice. Symptoms of the associated pathology are more common than those arising from the anomaly. Treatment should be specific to each case, as least invasive as possible and should aim at symptomatic resolution.
