AI Article Synopsis

  • - The study aimed to assess the safety and effectiveness of robot-assisted laparoscopic ureteroplasty using either a lingual mucosa graft (LMG) or an appendiceal flap (AF) in treating complex ureteral strictures in 16 patients.
  • - All surgeries were completed successfully without any needing to switch to open surgery, with an average operation time of about 210 minutes and a 100% success rate in addressing the strictures.
  • - The findings suggest that this robotic technique is both safe and effective, and the authors recommend it for wider use in similar surgical cases.

Article Abstract

Objective: To evaluate the feasibility, safety and efficacy of robot-assisted laparoscopic modified ureteroplasty using a lingual mucosa graft (LMG) or an appendiceal flap (AF) for complex ureteral strictures and summarize our experience.

Methods: A total of 16 patients with complex ureteral strictures (range: 1.5-5 cm) who underwent robotic-assisted laparoscopic-modified ureteroplasty and were admitted to our hospital from May 2022-October 2023 were retrospectively analyzed. We used modified presuture methods in patients who needed the posteriorly augmented anastomotic technique to reduce anastomotic tension. Perioperative variables and outcomes were recorded for each patient.

Results: The operation under robot-assisted laparoscopy was successfully performed in all sixteen patients (12 with LMG ureteroplasty and 4 with AF ureteroplasty) without conversion to open surgery. The mean length of the ureteral structure was 2.90 ± 0.90 cm (range: 1.5-5 cm), the mean operation duration was 209.69 ± 26.74 min (range: 170-255 min), the median estimated blood loss was 75 (62.5) ml (range: 50-200 ml), and the duration of postoperative hospitalization was 10.44 ± 2.10 d (range: 7-14 d). The follow-up time in this group was 6 ~ 21 months. The success rate of the surgery was 100%.

Conclusion: Robot-assisted laparoscopic modified ureteroplasty using AF or LMG is a safe and feasible operation for complex ureteral strictures and deserves to be popularized.
