Introduction
Cancer and kidney disease are closely connected, and many cancer patients develop kidney-related complications during diagnosis, chemotherapy, immunotherapy, targeted therapy, radiation treatment, or after cancer surgery. Onco nephrology is a specialized field that focuses on preventing, diagnosing, and treating kidney problems in patients with cancer.
Kidney complications may occur due to the cancer itself, cancer medications, dehydration, infections, electrolyte disturbances, urinary obstruction, or reduced blood flow to the kidneys. Early recognition and specialized nephrology care are essential to preserve kidney function, allow safe continuation of cancer treatment, and improve overall outcomes.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive onco nephrology care, advanced kidney evaluations, chemotherapy-related kidney monitoring, acute kidney injury management, dialysis care, kidney transplant evaluation, and long-term kidney health management for cancer patients.
What Is Onco Nephrology?
Onco nephrology is the branch of nephrology that focuses on kidney health in patients with cancer.
The primary goals are to:
-
Prevent kidney damage during cancer treatment
-
Manage acute kidney injury
-
Treat chronic kidney disease in cancer patients
-
Monitor kidney function during chemotherapy
-
Correct electrolyte imbalances
-
Manage proteinuria and blood pressure
-
Provide dialysis when necessary
-
Support safe cancer treatment
Nephrologists work closely with oncologists to optimize both cancer care and kidney function.
Why Do Cancer Patients Develop Kidney Problems?
Several factors may affect kidney function during cancer treatment.
Chemotherapy-Related Kidney Injury
Some chemotherapy medications can affect the kidneys and reduce kidney function.
Immunotherapy-Related Kidney Damage
Certain immunotherapy drugs may trigger inflammation of the kidneys.
Dehydration
Cancer patients may develop dehydration due to:
-
Vomiting
-
Diarrhea
-
Poor oral intake
-
Fever
-
Treatment side effects
Dehydration can significantly impair kidney function.
Urinary Tract Obstruction
Tumors affecting the urinary tract may block urine flow and damage the kidneys.
Multiple Myeloma
This blood cancer commonly affects kidney function through abnormal protein production.
Tumor Lysis Syndrome
Rapid destruction of cancer cells may release large amounts of potassium, phosphate, and uric acid, leading to acute kidney injury.
Infections
Cancer patients often have weakened immunity, increasing the risk of kidney and urinary tract infections.
Common Kidney Problems in Cancer Patients
Acute Kidney Injury (AKI)
A sudden decline in kidney function requiring urgent evaluation and treatment.
Chronic Kidney Disease (CKD)
Long-term kidney damage that may worsen during cancer treatment.
Protein in Urine (Proteinuria)
May occur due to certain cancer therapies or kidney involvement by cancer.
Electrolyte Imbalances
Common abnormalities include:
-
High potassium
-
Low sodium
-
High phosphate
-
High uric acid
Hypertension
Cancer therapies may contribute to elevated blood pressure and kidney stress.
Nephrotic Syndrome
Some cancers and cancer treatments can cause significant protein leakage in the urine.
Symptoms of Kidney Problems in Cancer Patients
Symptoms may include:
-
Swelling of the feet or ankles
-
Reduced urine output
-
Foamy urine
-
Blood in the urine
-
Fatigue
-
Weakness
-
Nausea and vomiting
-
High blood pressure
-
Shortness of breath
-
Muscle cramps
-
Persistent itching
-
Confusion in severe kidney failure
Some patients may have no symptoms, making regular kidney monitoring extremely important.
How Is Onco Nephrology Evaluation Performed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a detailed kidney assessment.
Medical History and Physical Examination
The doctor reviews:
-
Cancer type
-
Cancer treatment history
-
Chemotherapy medications
-
Immunotherapy
-
Blood pressure
-
Urine output
-
Kidney disease history
Blood Tests
Important investigations include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Electrolytes
-
Calcium
-
Phosphate
-
Uric acid
-
Complete Blood Count (CBC)
These tests help detect kidney injury and treatment-related complications.
Urine Tests
Urine investigations may include:
-
Routine urinalysis
-
Protein estimation
-
Albumin-to-Creatinine Ratio (ACR)
-
Urine microscopy
-
Urine culture when indicated
Imaging Studies
Imaging may include:
-
Kidney ultrasound
-
CT scan
-
MRI when clinically indicated
These studies help identify obstruction, hydronephrosis, tumors, or structural kidney abnormalities.
Additional Testing
Some patients may require:
-
Kidney biopsy
-
Immunological testing
-
Specialized nephrology investigations
These help determine the exact cause of kidney dysfunction.
Treatment in Onco Nephrology
Treatment is individualized according to the patient’s cancer, kidney function, and overall medical condition.
Hydration Therapy
Careful fluid management helps protect the kidneys during cancer treatment.
Medication Adjustment
Kidney function often affects chemotherapy dosing.
The nephrologist works with the oncology team to adjust medications safely.
Blood Pressure Control
Maintaining healthy blood pressure helps preserve kidney function.
Electrolyte Management
Treatment may be required for:
-
High potassium
-
High phosphate
-
High uric acid
-
Low sodium
Tumor Lysis Syndrome Management
Aggressive hydration and medications may be necessary to prevent kidney injury.
Dialysis
Some patients with severe acute kidney injury or advanced kidney failure may require temporary or long-term dialysis.
Dialysis decisions are individualized and coordinated with the oncology team.
Can Cancer Treatment Continue with Kidney Disease?
In many cases, yes.
With careful monitoring, medication adjustments, hydration management, and nephrology support, many patients can continue receiving effective cancer treatment safely.
Early nephrology involvement often improves treatment options.
Protecting Kidney Function During Cancer Treatment
Patients can support kidney health by:
-
Drinking fluids as advised
-
Reporting reduced urine output
-
Monitoring blood pressure
-
Attending regular kidney function testing
-
Avoiding unnecessary painkillers
-
Taking medications exactly as prescribed
-
Reporting swelling, nausea, or urinary symptoms promptly
Close monitoring is especially important during chemotherapy and immunotherapy.
