Bilateral Wilms Tumor With Ureteral Extension

Area of Science:

• Pediatric Oncology
• Urologic Oncology
• Nephrology

Background:

• Wilms tumor is the most common primary renal malignancy in children.
• Ureteral extension of Wilms tumor is an exceptionally rare clinical presentation.
• Bilateral involvement further complicates the diagnostic and therapeutic approach.

Observation:

• A case of bilateral Wilms tumor with unilateral ureteral extension into the urinary bladder is presented.
• The tumor's unusual extension pattern required meticulous diagnostic workup.
• Surgical strategy was tailored to address the specific anatomical challenges.

Findings:

• Successful oncologic control was achieved through comprehensive management.
• Renal function preservation was a key objective and outcome.
• This case highlights a rare but significant variant of pediatric kidney cancer.

Implications:

• Emphasizes the need for thorough evaluation in pediatric renal masses, even with atypical presentations.
• Informs surgical planning for rare Wilms tumor extensions to optimize outcomes.
• Contributes to understanding the spectrum of Wilms tumor behavior and management strategies.
