Retroperitoneal laparoscopy management for ureteral fibroepithelial polyps causing hydronephrosis in children: A report of five cases

Ureteral fibroepithelial polyps are rare but rather important as they can cause UPJ obstruction, which often manifests as hydronephrosis. It is most important to confirm the site of ureteral obstruction before surgery as this may have an effect on the surgical management. It is recommended that UFP be successfully managed in children with retroperitoneal laparoscopy.471Figure. Intraoperative findings of ureteral fibroepithelial polyps and the gross samples.
