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 ectopia and ureterolithiasis, which violates the Weigert-Meyer law. The duplicated ureter arose from a lower-pole calyx and drained inferiorly into the ipsilateral vas. A presentation of the case is followed by a comparison to the only known similar one, reported in 1988. A possible embryologic hypothesis for this anomaly is discussed.
