Transverse ureteral advancement technique of ureteroneocystostomy (Cohen reimplant) and a modification for difficult cases (experience with 121 ureters).
We reimplanted 121 ureters by the Cohen technique. A modification is introduced for difficult cases, making the Cohen technique more adaptable for dilated ureters and small bladders. Radiographic studies obtained at least 6 months after reimplantation revealed only 1 case of persistent reflux (grade I), no case of contralateral reflux and no obstruction. Even though the series included 35 ureters with grade V primary reflux and 7 primary obstructive megaureters, only 7 ureters were tapered. This finding suggests that the Cohen method might require tapering in a smaller percentage of cases compared to other reimplantation techniques.
