Laparoscopic nephroureterectomy for Wilms' tumor: oncologic considerations

Area of Science:

• Pediatric Oncology
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Wilms tumor is the most common pediatric kidney malignancy.
• Traditional treatment involves open surgical resection.
• Advancements in laparoscopic surgery prompt exploration for Wilms tumor treatment.

Observation:

• A 2-year-old girl presented with a large Wilms tumor (18x13 cm) with metastatic disease.
• Neoadjuvant chemotherapy was administered.
• Laparoscopic tumor resection with radical nephroureterectomy and metastasis resection was performed using multiple ports.

Findings:

• The laparoscopic procedure included retroperitoneal lymph node dissection and peritoneal metastasis resection.
• Specimens were retrieved using an endoscopic bag through a small incision.
• The patient experienced an uncomplicated recovery and remained disease-free at 19 months.

Implications:

• Minimally invasive laparoscopic techniques can be considered for Wilms tumor resection in children.
• Careful adherence to oncologic principles is crucial for successful outcomes.
• This approach may offer a less invasive option for pediatric kidney cancer surgery.
