Insights
Benign fibroepithelial polyps are a rare cause of ureteropelvic junction obstruction in children. Surgical resection and pyeloplasty successfully treated a 9-year-old boy with this condition.
Area of Science:
- Pediatric Urology
- Surgical Pathology
Background:
- Ureteropelvic junction (UPJ) obstruction is a common congenital anomaly in children.
- Fibroepithelial polyps are uncommon causes of UPJ obstruction, particularly in the pediatric population.
Observation:
- A 9-year-old boy presented with symptoms of UPJ obstruction.
- Intravenous pyelography revealed left hydronephrosis and filling defects at the UPJ.
- Surgical exploration identified multiple polypoid masses obstructing the ureteropelvic junction.
Findings:
- Histological examination confirmed the diagnosis of benign fibroepithelial polyps.
- The polyps were causing significant obstruction of the ureteropelvic junction.
Implications:
- This case highlights the importance of considering rare causes of UPJ obstruction in pediatric patients.
- Surgical management involving resection and pyeloplasty is effective for fibroepithelial polyps causing UPJ obstruction.
- Further research into the etiology and optimal management of these rare pediatric urological lesions is warranted.
Abstract:
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 fibroepithelial 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.
