[Bilateral ureteral polyps in children: a case report].

Area of Science:

• Pediatric Urology
• Surgical Oncology
• Nephrology

Background:

• Fibroepithelial polyps are rare, benign tumors of mesodermal origin affecting the ureter, predominantly in children.
• Common symptoms include hematuria and flank pain due to urinary tract obstruction.
• The exact etiology remains unclear, with a higher incidence observed in boys, often affecting the proximal ureter and ureteropelvic junction.

Observation:

• A case study of an 11-year-old boy presenting with bilateral fibroepithelial polyps causing ureteropelvic junction obstruction.
• The patient experienced obstruction on the left flank requiring pyeloplasty and had a history of similar obstruction on the right flank five years prior.
• Preoperative diagnosis of ureteral fibroepithelial polyps can be challenging.

Findings:

• The patient underwent successful surgical intervention involving polypectomy and pyeloureterostomy for the left ureteropelvic junction obstruction.
• The surgical procedure was completed without significant intraoperative or preoperative complications.
• This case highlights the recurrent nature of fibroepithelial polyps in some pediatric patients.

Implications:

• Polypectomy and pyeloureterostomy are effective treatment options for pediatric ureteral fibroepithelial polyps causing obstruction.
• Early diagnosis and prompt surgical management are crucial for favorable outcomes in pediatric patients with ureteral tumors.
• Further research into the etiology of fibroepithelial polyps may aid in developing targeted preventive or therapeutic strategies.
