    Abstract:
    INTRODUCTION: In bilateral VUR, Cohen cross-trigonal ureteric reimplantation is a popular but also controversial surgical approach. We present our own experience in a retrospective analysis. PATIENTS AND METHODS: Between 1990 and 2005, 41 children (26 girls, 15 boys) with bilateral reflux [92 renal units (RU)] underwent ureteric reimplantation. The mean age was 4.5 (0.3-12) years. Eight patients had ureteral duplication (six unilateral, two bilateral); 12 of 41 patients had no intraoperative ureteral stenting. Seven patients had prior surgery for VUR. A successful result was defined as absence of VUR, significant UVJ obstruction, or voiding dysfunction throughout the follow-up. RESULTS: The mean follow-up was 7.8 (0.5-15) years. Eight patients (19.5%) had 13 complications. One patient had an intraoperative small bowel lesion (2%). Six patients (14.6%) had UTI. Four patients (9.8%) showed transient UVJ obstruction. Three required a temporary percutaneous nephrostomy. Two of these patients had no intraoperative ureteral stenting. Recurrence of VUR was found in 2 patients (4.8%) and 2/92 RU (2.2%), respectively. Complications were more frequent in high-grade VUR, ureter duplex, or unstented ureteral reimplantation. Prior surgery for VUR did not influence the postoperative outcome. Postoperative voiding disorders were not observed. CONCLUSIONS: Two unilateral recurrences of VUR were observed, requiring a reoperation in one patient. A reoperation for UVJ obstruction was not necessary. Related to 92 RU the surgical success rate was 97.8%. Intraoperative ureteral stenting has to be considered with respect to the current discussion of shortening inpatient procedures. In our experience, the perioperative risk was elevated in patients with high-grade VUR or ureteral duplication.
