title: Improved success of antegrade ureteral catheterization via the lower pole calix using a Chuang reverse curve catheter: technical note.
abstract: Although antegrade ureteral catheterization is best approached from a middle or upper middle calix for the most favorable force vector, it is occasionally necessary to use a lower pole caliceal approach. A catheter technique is described for completing antegrade ureteral catheterization via the lower pole calix when conventional catheter-guidewire combinations fail.
