Introduction:
Ureteral duplications are a common malformation of the urinary tract. A complete triplication however, is very rare.
Case Report:
We report the case of a 26-year-old female patient admitted because of a septic disorder. Sonographic examination revealed right-sided hydronephrosis. A CT scan confirmed the rare anatomic abnormality of a ureter triplex. One of the three ureters was an obstructed mega-ureter. The dilated renal pelvis was punctured and pus drained. After clinical recovery of the patient, complete resection of the obstructed megaureter and the non-functional moiety was performed.
Conclusion:
This case illustrates an extraordinarily rare malformation of the urinary tract and describes an approach for treatment.
