Imaging Findings in Fibroepithelial Polyps Causing Ureteropelvic Junction Obstruction: Report of One Case

纖維上皮息肉造成腎盂輸尿管結合處阻塞的影像表現

並列摘要


Fibroepithelial polyps causing ureteropelvic junction obstruction are rarely reported in the pediatric age group. We report a 9-year-old boy who had ureteropelvic junction obstruction that proved to be owing to benign f ibroepi thelial polyps. Intravenous pyelography showed hydronephrosis with filling defects at the left ureteropelvic junction. Operative exploration revealed several finger-like polypoid neoplasms obstructing the lumen. The involved segment was resected and a dismembered pyeloplasty was performed. Fibroepithelial polyps were diagnosed by histology. The clinical imaging findings, features and methods of surgical treatment of this rare lesion are discussed.
