摘要

Background

Ureteral fibroepithelial polyps (FEPs) are rare, benign lesions in children that may cause ureteral obstruction. Bilateral ureters involvement is especially uncommon, and the optimal surgical approach remains debated.

Case presentation

A 3-year-old boy of East Asian ethnicity presented with intermittent abdominal pain for 2 weeks. Ultrasound and computed tomography (CT) imaging indicated severe hydronephrosis and dilatation in the bilateral upper ureters. Robot-assisted laparoscopic surgery (RALS) identified multiple FEPs in both ureters, and bilateral partial ureterectomy with end-to-end anastomosis was performed. At 12-month follow-up, no symptoms had recurred and hydronephrosis had significantly improved.

Conclusion

To our knowledge, this is the first reported case of bilateral ureteral FEPs treated via RALS in a single procedure, suggesting that RALS is feasible and safe for complex pediatric ureteral FEPs. Long-term follow-up is warranted to evaluate the risk of recurrence.
