Abstract
AbstractIntroductionThis study was performed to evaluate the differences in the perioperative results, renal function, and incidence of hydronephrosis over time between the use of Bricker anastomosis and Wallace anastomosis for robot‐assisted intracorporeal ileal conduit urinary diversion (RICIC).MethodsFifty‐five patients who underwent RICIC at two institutions were evaluated (Bricker, n = 23; Wallace, n = 32). We investigated changes in estimated glomerular filtration rate and hydronephrosis before surgery and at 3, 6, and 12 months after surgery.ResultsThe patients in the Bricker group were significantly older than those in the Wallace group. The urinary diversion time was significantly longer in the Bricker group. No significant difference in postoperative renal function was observed. Additionally, no significant difference was observed in the incidence of postoperative hydronephrosis. However, the incidence of right hydronephrosis tended to be high overall, especially in the Wallace group. No patients in either group required repair surgery or ureteral stent placement.ConclusionsIn patients undergoing RICIC, there was no difference in postoperative renal function or the incidence of hydronephrosis between Wallace and Bricker anastomosis. Symptomatic hydronephrosis was not observed in either group. The present study showed that each method was equally effective and safe.
