Purpose: There are different approaches for the repair of benign ureteral stricture. Traditionally, these procedures have been performed by open surgery. With development of technology, minimally invasive approaches have been performed widely. The purpose of this study is to compare the outcome, feasibility, and perioperative results of robot-assisted, laparoscopic and open surgery method.

Materials and Methods: We retrospectively collected ureteropelvic junction obstruction and ureteral stricture patients who received reconstruction surgery from January, 2006 to August, 2017. Statistical analyses were performed for patients’ characteristics, perioperative data and clinical outcomes.

Results: Totally 91 patients were enrolled for analysis. We categorized these patients into three groups according the operative approaches. Thirty three patients received reconstructive surgery by robot-assisted method (Group I), 26 patients by laparoscopic method (Group II) and 32 patients by open method (Group III). All the procedures were completed successfully without open conversion. Average estimated blood loss, total operative time and complication rate showed no significant difference. Mean post-operative days of hospitalization were 6.4 ± 3.1 for Group I, 5.2 ± 1.4 for Group II and 8.1 ± 3.4 for Group III (P=0.001). At a median follow-up of 17.8 months, recurrence rate was 15.2%, 23.1% and 21.9% in Group I, Group II and Group III, respectively (P=0.700). These patients received further interventions such as long-term percutaneous nephrostomy, long-term double-J stent placement and balloon dilatation.

Conclusions: In our analysis, minimally invasive approach for ureteral reconstruction surgery could minimize the post-operative hospital stay. There is a tendency of lower recurrent rate by robot-assisted method although it showed no significant difference in limited case numbers. Thus, we need to collect more cases to make the conclusions in the future.
