Summary
Robotic appendiceal ureteroplasty (RAU) offers a 100% success rate for complex ureteral strictures. This innovative technique utilizes the appendix for reconstruction, providing a safe and effective solution for patients.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Regenerative Medicine
Background:
- Complex ureteral strictures present a significant reconstructive challenge.
- The appendix serves as an autologous graft option for ureteral repair, distinct from oral mucosal grafts due to its inherent vascularity.
Purpose of the Study:
- To detail the techniques of robotic appendiceal ureteroplasty (RAU).
- To assess the midterm efficacy and safety of RAU for ureteral reconstruction.
Main Methods:
- A single-institution study involving 31 patients with right-sided complex ureteral strictures from May 2019 to September 2024.
- All procedures utilized a robotic single-docking approach for RAU.
- Prospective collection of perioperative and follow-up data.
Main Results:
- The mean operative time was 176.4 minutes, with a mean estimated blood loss of 42.7 ml and a 4.5-day hospital stay.
- No open conversions or major perioperative complications were recorded.
- A 100% overall success rate (30/30) was achieved at a median follow-up of 28 months.
Conclusions:
- Robotic appendiceal ureteroplasty (RAU) demonstrates a safe and effective method for treating complex right-sided ureteral strictures.
- Careful patient selection, considering stricture characteristics and appendix condition, is crucial for optimal outcomes.
