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.
