URETERAL DUPLICATION WITH LOWER POLE ECTOPIA TO THE VAS - A CASE-REPORT OF AN EXCEPTION TO THE WEIGERT-MEYER LAW

We report an unusual case of ureteral duplication with lower-pole ecto pia and ureterolithiasis, which violates the Weigert-Meyer law. The du plicated ureter arose from a lower-pole calyx and drained inferiorly i nto the ipsilateral vas. A presentation of the case is followed by a c omparison to the only known similar one, reported in 1988. A possible embryologic hypothesis for this anomaly is discussed.
