Robotic Surgical Reconstruction for Ureteral Strictures from Endometriosis
Overview
This multi-center study evaluated robotic ureteral reconstruction (RUR) in 19 patients with ureteral strictures caused by endometriosis. At a median follow-up of 22.5 months, surgical success was achieved in 94.7% of cases, demonstrating durable outcomes with low complication rates.
Background
Ureteral involvement in endometriosis is rare but clinically significant, affecting about 1% of women with the disease. Endoscopic treatments often have limited long-term success, necessitating surgical reconstruction in complex cases. Traditional approaches focus on ureterolysis, but extensive or infiltrative lesions may require definitive reconstructive surgery. Robotic techniques offer a minimally invasive option for managing these challenging strictures.
Robotic ureteral reconstruction was performed successfully in 19 patients with endometriosis-induced ureteral strictures.
Most strictures (78.9%) were located in the distal ureter and all patients had hydronephrosis.
Various RUR techniques were utilized based on stricture location and severity, with refluxing reimplantation being the most common (47.4%).
The median operative time was approximately 3.3 hours with minimal blood loss.
Only one patient (5.3%) experienced a major postoperative complication requiring intervention.
At a median follow-up of 22.5 months, 94.7% of patients achieved surgical success without need for further intervention.
Clinical Implications
Robotic ureteral reconstruction offers a safe and effective surgical option for managing complex ureteral strictures caused by endometriosis, especially when ureterolysis alone is insufficient. The high success rate and low complication profile support its use in specialized centers. Careful preoperative planning and tailored surgical techniques based on stricture characteristics are essential for optimal outcomes.
Conclusion
This multi-institutional study demonstrates that robotic ureteral reconstruction provides durable and effective treatment for endometriosis-related ureteral strictures, with excellent mid-term outcomes and minimal morbidity.
