“…The reported success rate of Gil-Vernet is close to previous reports of high success rate in its open transvesical technique [3][4][5][6][7][8][9][10] . This success rate is much higher than the success rates associated with a single session of endoscopic submucosal injection of bulking agents (50-65%) [19][20][21] .…”

Introduction: This study was designed to evaluate factors contributing to failure in Gil-Vernet antireflux operation. Materials and Methods: 96 patients (150 refluxing units; median (range) age, 60 (12–180) months; M/F, 11/85) with primary vesico-ureteral reflux were included. Trigonoplasty was done according to a modified Gil-Verent procedure. Relapse was diagnosed on the postoperative direct radionuclide cystography (DRNC) 3 or 6 months after operation. Demographic and intraoperative data were used to assess factors contributing to failure. Results: Resolution of reflux in postoperative DRNC was observed in 87 patients (90.6%) and in 138 refluxing units (92.0%). In patients who were followed 3–6 months, one relapse occurred (3%) versus 8 relapses in those who were followed 24–39 months (12%). Relapse in refluxing units was related to the history of voiding symptoms (30 vs. 3%, p < 0.001), history of breakthrough infections (20 vs. 3%, p = 0.001), golf or stadium like ureteral orifice appearance (15 vs. 4%, p = 0.02), and less distance of ureteral orifices from each other (p < 0.001). Conclusions: Trigonoplasty success rate may decrease with long-term follow-up. In multivariable analysis, patients with history of voiding dysfunction, breakthrough infection, golf/stadium like ureteral orifices, and less distant ureteral orifices are at a higher risk of relapse.

Significant controversy exists regarding vesicoureteral reflux (VUR) management, due to lack of sufficient prospective studies. The rationale for surgical management is that VUR can cause recurrent episodes of pyelonephritis and long-term renal damage. Several surgical techniques have been introduced during the past decades. Open anti-reflux operations have high success rate, exceeding 95%, and long durability. The goal of this article is to review the Gil-Vernet trigonoplasty technique, which is a simple and highly successful technique but has not gained the attention it deserves. The mainstay of this technique is approximation of medial aspects of ureteral orifices to midline by one mattress suture. A unique advantage of Gil-Vernet trigonoplasty is its bilateral nature, which results in prevention from contralateral new reflux. Regarding not altering the normal course of the ureter in Gil-Vernet procedure, later catheterization of and retrograde access to the ureter can be performed normally. There is no report of ureterovesical junction obstruction following Gil-Vernet procedure. Gil-Vernet trigonoplasty can be performed without inserting a bladder catheter and drain on an outpatient setting. Several exclusive advantages of Gil-Vernet trigonoplasty make it necessary to reconsider the technique role in VUR management.

Polymers filled with inorganic nanoparticles have become interesting materials as dielectrics because of their improved mechanical and electrical properties compared with the unfilled polymers and with polymer microcomposites. These improvements are mainly due to the large surface area of nanoparticles and new polymer-nanofiller interface characteristics. In the present work, polyethylene nanocomposites with SiO 2 and Al 2 O 3 nanoparticles were prepared by melt mixing. Mechanical and electrical properties of these composites were determined and morphological aspects were revealed by scanning electron microscopy, wide-angle X-ray diffraction, and atomic force microscopy. The effect of nanostructure and the importance of nanofiller dispersion were analyzed in connection with mechanical and electrical properties.
