    Abstract:
    INTRODUCTION: Uretero-enteric stenosis may raise some specific problems due to difficulties concerning the retrograde access. The aim of our study was to evaluate the effectiveness of antegrade flexible ureteroscopic approach for this specific pathology. MATERIAL AND METHODS: Between January 2002 and June 2008, a number of 7 patients underwent antegrade flexible ureteroscopy for uretero-enteric stenosis: 3 patients with stenosis of the uretero-neobladder anastomosis (Group I), 2 patients with stenosis of the uretero-sigmoidian implantation (Group II) and 2 patients with stenosis of the ureteral implantation in an ileal conduit (Group III). In Group I, we performed antegrade Nd:YAG laser star incision in 2 cases and balloon dilation in 1 case. In Group II, the antegrade Nd:YAG laser star incision was applied in 1 case and balloon dilation was performed in the other one. In Group III, we performed antegrade insertion of the guidewire followed by retrograde cold-knife incision in one case, and bipolar ureteral approach (cut-to-the-light technique) in 1 case. RESULTS: The mean operative time was 58 min. (range 25 to 120 min). We didn't describe major intraoperative complications. Ultrasonography, IVP and isotopic renogram (in selected cases) have been the follow-up evaluation methods. Postoperatively, 2 cases from Group I and all cases from Groups II and III had a good evolution, with significant reduction of the hydronephrosis degree at 6, 12 and 18 months. One patient from Group I, in which balloon dilation of the stenosis was performed, developed recurrence at 6 months. CONCLUSIONS: According to our experience, antegrade flexible ureteroscopic approach may represent an efficient and safe technique in uretero-enteric stenosis treatment. Being a minimally invasive approach, this procedure has a reduced rate of complications and good anatomical and functional results.
