Therapeutic Nephrectomy for Nutcracker Syndrome

If you have been diagnosed with Nutcracker Syndrome, you may be able to donate your
kidney to someone in need of a kidney transplant.
This compression can restrict blood flow from the left kidney and may lead to a range of
symptoms, including but not limited to:

• Flank or abdominal pain

• Hematuria (blood in the urine)

• Proteinuria (protein in the urine)

• Pelvic congestion in females

• Varicocele in males

Symptoms and severity can vary significantly from patient to patient.

​

Standard Treatment Approaches for NCS

Treatment varies based on severity and may include:

• Conservative management (monitoring, lifestyle adjustments)

• Medication for symptom relief

• Left renal vein transposition (LRVT): A surgical procedure that relocates the left renal

vein to a lower position on the inferior vena cava (a large vein that carries blood
to the heart)

• Left renal vein stenting: In severe cases, doctors may place a stent in the vein,

which expands the vein to allow for proper blood flow to the heart.

• Transplantation: In severe cases, patients may be given two transplant options to

treat their symptoms:

1. Autotransplantation, where the nutcracker kidney is surgically removed

from the patient and then transplanted back into the patient in the pelvis,

near the bladder.

2. Therapeutic nephrectomy, where the patient elects to undergo a

nephrectomy and chooses to donate the kidney to a patient with end-

stage renal disease.​

​

Treatment decisions depend on anatomy, symptom severity, patient age, comorbidities,
and multidisciplinary surgical evaluation. For a discussion comparing therapeutic
nephrectomy and renal autotransplantation, see this blog post on therapeutic nephrectomy vs. autotransplantation.

What Is a Therapeutic Nephrectomy?

With therapeutic nephrectomy, the affected kidney is surgically removed. This approach
is typically recommended when:

• Patients are good candidates and seeking a definitive solution, as pursuing other
  surgical options first may make therapeutic nephrectomy more difficult or prevent it from
  being an option in the future.

• Symptoms are severe and significantly affect quality of life.

• Other interventions have failed, or patients wish to avoid repeated procedures that
  may not provide lasting relief.

• It has a high likelihood of relieving symptoms associated with Nutcracker Syndrome.

​

Advantages of Therapeutic Nephrectomy

• Less complex surgery: Compared to renal autotransplantation or LRVT, nephrectomy is typically considered a less complex
  operation.

• Lower chance of complications: Laparoscopic donor nephrectomy is generally

a safe procedure, and serious complications are uncommon. Additionally, recent
data estimates a mortality rate of 1 in 10,000 procedures.  

• Shorter recovery time: Many patients who undergo therapeutic nephrectomy recover faster than they would from other procedures.

• Potential symptom relief: For some, removing the problematic kidney offers

rapid and lasting relief from pain, hematuria, and other symptoms.

• Opportunity to help others: If the kidney is otherwise healthy and you meet

donor eligibility criteria, the removed kidney may be donated to a person with
end-stage renal disease who is awaiting a transplant. This allows patients to
potentially relieve their own symptoms while giving the gift of life to someone
else.

 

The National Kidney Registry (NKR) offers a comprehensive testing process for individuals diagnosed with Nutcracker Syndrome who are considering kidney donation. This process includes a 5-minute introductory questionnaire to determine eligibility and a thorough medical evaluation. The NKR also provides support and protections for living kidney donors, including Donor Shield, which offers reimbursement for lost wages, travel, lodging, and dependent care.

​

What is the evaluation process to determine if I am eligible to donate?

The evaluation process for Nutcracker Syndrome involves a series of medical tests and assessments to determine if a patient is a suitable candidate for kidney donation, including:​​

• Medical Evaluation: Patients undergo a thorough medical evaluation, which includes bloodtests, urine tests, imaging, and consultations with medical professionals to ensure they are fully informed about the process and have all the necessary resources. 

• Pre-workup Labs: There is no charge for any pre-workup labs related to the donation process. 

• Additional Testing: Patients may undergo additional testing to verify their condition and 

assess their suitability as a kidney donor. These tests can include a CT, venogram, or MRI. 

• Documentation: Patients should bring any documentation they have received about their Nutcracker Syndrome diagnosis, including imaging and lab work, to the evaluation.
