A case of ureteral triplication associated with ureteropelvic junction obstruction

Int Urol Nephrol. 2007;39(3):755-7. doi: 10.1007/s11255-006-9087-4. Epub 2007 Apr 14.


Ureteral triplication is one of the rarest malformations of the upper urinary tract. The association of ureteral triplication and obstruction is even rarer. We report a case of ureteral triplication associated with hydronephrosis due to ureteropelvic junction (UPJ) obstruction at the middle pole ureter. To our knowledge, such a malformation has not been described previously.
