Surgery

​

Surgery for Wilms tumor is one of the most important parts of treatment for childhood kidney cancer and plays a central role in many pediatric oncology treatment plans. The goal of pediatric kidney cancer surgery is to safely remove the Wilms tumor, prevent the cancer from spreading, accurately determine the stage of the disease, and improve long-term survival outcomes for children diagnosed with Wilms tumor. Surgery for Wilms tumor is commonly combined with chemotherapy for pediatric kidney cancer and, in some cases, radiation therapy for Wilms tumor as part of a comprehensive childhood cancer treatment approach.

​

The most common surgery for Wilms tumor is a nephrectomy, a pediatric surgical procedure that removes part or all of the affected kidney depending on the size, stage, and location of the tumor. Children may undergo a radical nephrectomy, partial nephrectomy, or kidney-sparing surgery for bilateral Wilms tumor where both kidneys are affected. During nephrectomy surgery for Wilms tumor, nearby lymph nodes may also be examined or removed to determine whether the pediatric kidney cancer has spread beyond the kidney.

​

In some cases, children receive chemotherapy before nephrectomy surgery for Wilms tumor to shrink the tumor and make pediatric cancer surgery safer and more effective. Preoperative chemotherapy for Wilms tumor may help reduce the risk of tumor rupture during surgery while improving overall treatment outcomes. Children with stage 3 Wilms tumor, stage 4 Wilms tumor, relapsed Wilms tumor, or metastatic pediatric kidney cancer may require more extensive surgery combined with intensive chemotherapy, radiation therapy, or advanced pediatric oncology treatment protocols.

​

Recovery after surgery for Wilms tumor varies depending on the child’s age, overall health, tumor stage, and the complexity of the pediatric surgical procedure. Following pediatric nephrectomy surgery, children are closely monitored during recovery for pain management, infection prevention, kidney function, and overall healing. Some children may require temporary activity restrictions or additional supportive care during the recovery period.

​

Long-term follow-up care after surgery for Wilms tumor remains an important part of pediatric cancer survivorship. Children who have undergone nephrectomy surgery for childhood kidney cancer often continue pediatric oncology follow-up appointments and survivorship monitoring to assess kidney function, growth and development, blood pressure, long-term health, and possible late effects of treatment. Advances in pediatric cancer surgery and modern pediatric oncology care continue to improve survival rates and long-term quality of life for children treated for Wilms tumor.

Types of Surgery for Wilms Tumor

Several types of surgery may be used to treat Wilms tumor in children depending on the stage of the pediatric kidney cancer, the size and location of the tumor, whether one or both kidneys are affected, and the child’s overall treatment plan. Pediatric oncology surgeons carefully select the safest and most effective surgical approach to remove the cancer while preserving as much healthy kidney tissue and long-term kidney function as possible.

​

Radical Nephrectomy for Wilms Tumor

​

A radical nephrectomy for Wilms tumor is the most common type of surgery used to treat unilateral childhood kidney cancer where only one kidney is affected. During a radical nephrectomy, the surgeon removes the entire affected kidney along with the Wilms tumor, surrounding fatty tissue, and in some cases nearby lymph nodes to help determine whether the cancer has spread beyond the kidney.

​

Radical nephrectomy surgery for pediatric kidney cancer is often combined with chemotherapy for Wilms tumor and, in some cases, radiation therapy depending on the stage and histology of the disease. Children with stage 3 Wilms tumor, stage 4 Wilms tumor, or metastatic Wilms tumor may require additional pediatric oncology treatments after surgery to reduce the risk of recurrence.

​

Most children are able to live healthy lives with one kidney after Wilms tumor treatment, although long-term survivorship monitoring and kidney function follow-up remain important following pediatric nephrectomy surgery.

​

Partial Nephrectomy for Pediatric Kidney Cancer

A partial nephrectomy for Wilms tumor is a kidney-sparing surgical procedure that removes only the tumor and a small margin of surrounding kidney tissue while preserving as much healthy kidney function as possible. Partial nephrectomy surgery may be considered in selected children with smaller tumors, favorable tumor location, bilateral Wilms tumor, or situations where preserving kidney tissue is especially important.

​

Kidney-sparing surgery for childhood kidney cancer can help reduce the risk of long-term kidney complications, chronic kidney disease, or reduced kidney function later in life. Pediatric oncology teams carefully evaluate imaging, tumor stage, and surgical safety before recommending partial nephrectomy for Wilms tumor treatment.

​

Children undergoing partial nephrectomy for pediatric kidney cancer continue long-term follow-up care and survivorship monitoring to assess kidney health, blood pressure, growth and development, and possible late effects of treatment.

​

Bilateral Kidney-Sparing Surgery for Bilateral Wilms Tumor

Children diagnosed with bilateral Wilms tumor, where tumors affect both kidneys, may require highly specialized bilateral kidney-sparing surgery as part of their pediatric oncology treatment plan. The goal of bilateral kidney surgery for Wilms tumor is to remove cancerous tissue while preserving as much healthy kidney tissue and long-term kidney function as possible.

​

Treatment for bilateral Wilms tumor often begins with chemotherapy to shrink tumors before surgery and improve the chances of successful kidney preservation. Pediatric cancer surgeons then carefully remove tumors from both kidneys while attempting to minimize damage to healthy tissue.

​

Because children with bilateral pediatric kidney cancer face a higher risk of long-term kidney complications, ongoing survivorship care after bilateral kidney-sparing surgery remains extremely important. Long-term follow-up after bilateral Wilms tumor treatment may include kidney function monitoring, blood pressure assessment, growth and developmental monitoring, and evaluation for chronic kidney disease or other late effects of childhood cancer treatment.

Recovery After Nephrectomy in Children

Most children recover well following nephrectomy surgery for Wilms tumor, although recovery after pediatric kidney cancer surgery can vary depending on the child’s age, overall health, tumor stage, type of nephrectomy performed, and whether additional treatments such as chemotherapy or radiation therapy are required. Recovery from nephrectomy surgery for childhood kidney cancer is carefully monitored by pediatric oncology teams to support healing, manage symptoms, and help children safely return to normal daily activities.

​

Immediately after surgery for Wilms tumor, children are typically monitored in the hospital for pain control, infection prevention, wound healing, kidney function, hydration, and overall recovery. Some children may experience temporary fatigue, reduced appetite, abdominal discomfort, constipation, or limited mobility during the early recovery period following pediatric nephrectomy surgery. Hospital stays can vary depending on the complexity of the surgery and the child’s overall condition.

​

Families are usually provided with detailed guidance regarding recovery after nephrectomy surgery in children, including wound care, activity restrictions, nutrition, hydration, medication schedules, and signs of possible complications. Pediatric oncology teams may also provide support relating to emotional recovery, school reintegration, physical activity, and coping with the impact of childhood cancer treatment.

​

Children who undergo radical nephrectomy for Wilms tumor often adapt very well to living with one kidney after childhood cancer treatment. The remaining kidney is typically able to perform the body’s necessary kidney functions effectively, although long-term kidney monitoring after nephrectomy remains important throughout survivorship.

​

Long-term follow-up care after pediatric kidney cancer surgery may include:

​

• Kidney function monitoring

• Blood pressure assessment

• Growth and developmental monitoring

• Imaging surveillance for recurrent Wilms tumor

• Assessment of late effects from chemotherapy or radiation therapy

• Nutritional and survivorship support

Children treated for bilateral Wilms tumor or those who undergo kidney-sparing surgery may require even closer long-term monitoring to assess preserved kidney function and reduce the risk of chronic kidney disease later in life.

​

Advances in pediatric oncology surgery, anesthesia, pain management, and survivorship care continue to improve recovery outcomes and long-term quality of life for children undergoing nephrectomy surgery for Wilms tumor. With ongoing medical follow-up and supportive care, many children treated for pediatric kidney cancer are able to return to school, physical activities, and normal childhood development after recovery.
