Comparison Bricker's and Wallace's anastomoses in ileal conduit: Retrospective, multicenter study

Objectives. - To compare Bricker and Wallace anastomosis in ileal conduit and search other risk factors of hydronephrosis. Methods. - Retrospective study in two French Hospitals with two different surgical practices. Hydronephrosis are separated in two groups: complicated hydronephrosis requiring reoperation and no complicated hydronephrosis. Results. - One hundred and sixty patients were included in the study and 317 renal units were explored (141 in Bricker's group and 176 in Wallace's group). The rate of complicated and non-complicated hydronephrosis are respectively 9.9 and 20.6% in Bricker's group against 10.8 and 13.6% in Wallace's group, without significant difference (P=0.8 and 0.1). In the other risk factors, only body mass index over 25 kg/m(2) was found as significant for complicated hydronephrosis. The left side and preoperative hydronephrosis are only associated to a risk of no complicated hydronephrosis (P=0.006 and 0.026). Conclusion. - We found no difference between the two most common types of ureteroenteric anastomotic techniques. However, a high body mass index increases the rate of reoperation for hydronephrosis.
