title: Ureteral crossover method: animal experiment for correction of reflux.
abstract: The ureteral crossover method for the correction of bilateral vesicoureteral reflux, characterized by ureteral overlapping in the submucosal space and directing the submucosal tunnels toward a point other than the bladder neck, has been tested in 10 dogs. The operation was successful in 18 of 20 ureters (90%). This technique has two merits: (1) availability of a sufficient length of submucosal ureter without altering the original ureteral entrance bilaterally; and (2) easy ligation of the new orifices in the middle of the operative field. It is concluded that ureteral overlapping does not harm the ureteral physiology and that the surgical validity of this method has been verified.
