Summary
Fibroepithelial polyps, rare benign ureter tumors, can obstruct the ureteropelvic junction in children. Surgical resection and pyeloplasty successfully treated a pediatric case, resolving obstruction and promoting growth.
Area of Science:
- Urology
- Pediatric Surgery
- Oncology
Background:
- Fibroepithelial polyps are rare, benign ureteral tumors originating from mesodermal tissue.
- These lesions can lead to ureteropelvic junction obstruction, particularly in pediatric patients.
- Ureteropelvic junction obstruction can cause significant symptoms, including pain and impaired kidney function.
Observation:
- An 11-year-old boy presented with chronic left abdominal and flank pain, and short stature.
- Intravenous pyelography revealed left hydronephrosis without clear filling defects at the ureteropelvic junction.
- Surgical exploration identified multiple finger-like polyps obstructing the ureteropelvic junction.
Findings:
- Segmental resection of the affected ureter segment and dismembered pyeloplasty were performed.
- Histological examination confirmed the diagnosis of fibroepithelial polyps.
- The patient experienced an uncomplicated postoperative recovery.
Implications:
- Surgical intervention for ureteropelvic junction obstruction caused by fibroepithelial polyps is effective in children.
- Successful treatment led to the resolution of obstruction and normalization of growth.
- This case highlights the importance of considering rare benign tumors in the differential diagnosis of pediatric ureteropelvic junction obstruction.
