[Fibroepithelial polyps of the upper urinary tract: their diagnostic evaluation and treatment in pediatrics].

OBJECTIVE

To establish the diagnostic criteria, analyze the histological patterns of benign and malignant ureteral and renal pelvic polyps in pediatric patients and discuss the best treatment option based on the final diagnosis.

METHODS/

RESULTS

The literature is reviewed with special reference to the diagnostic and therapeutic aspects of fibroepithelial polyps of the upper urinary tract in pediatric patients. An additional case with benign cytological and radiological findings is described. The patient underwent partial pyeloureteral resection. Histological analysis of the surgical specimen confirmed a fibroepithelial polyp.

CONCLUSIONS

We emphasize the importance of adequate preoperative evaluation, precise identification of the base of the lesion for a correct choice of the surgical approach, and the advantages of complete segmental resection and reanastomosis over simple excision of the polyp.
