title: Initial results with the Cohen cross-trigonal ureteroneocystotomy.
abstract: Between January 1976 and December 1980, 109 children with 157 ureters with reflux were seen in consultation. Of these ureters 52 were operated upon using the Cohen cross-trigonal technique, while 105 were followed conservatively. The operative procedure is a complete intravesical ureteral mobilization followed by the creation of a submucosal tunnel across the base of the bladder. Followup studies, including an excretory urogram and voiding cystourethrogram, showed minimal hydronephrosis in 1 ureter and persistent grade I reflux in 1 ureter. Evaluation of these initial results indicates that the Cohen cross-trigonal ureteroneocystotomy is a safe and effective antireflux procedure.
