Summary
This study presents a novel robot-assisted surgical technique using appendiceal interposition and a Boari flap to treat long right ureteral strictures, demonstrating a safe and effective solution.
Area of Science:
- Urology
- Surgical Innovation
- Reconstructive Surgery
Background:
- Long ureteral strictures pose significant reconstructive challenges.
- Existing surgical techniques may have limitations in addressing extensive ureteral damage.
Purpose of the Study:
- To describe and evaluate a combined robot-assisted appendiceal interposition and Boari flap technique.
- To assess the safety and feasibility of this novel approach for long right ureteral strictures.
Main Methods:
- The technique involves ureteral dissection, stricture resection, psoas hitch, and preparation of a tubular appendix.
- The ureteral stump is anastomosed to the appendix apex, and the appendix base is connected to a bladder flap.
Main Results:
- The described surgical procedure was successfully performed.
- The patient demonstrated good recovery with no complications at the final follow-up.
Conclusions:
- Robot-assisted appendiceal interposition combined with a Boari flap is a safe and feasible option.
- This technique offers a viable solution for complex, long right ureteral strictures.
