  • The Basics

What Is Nephrology?

Nephrology is the branch of internal medicine focused on the function of the kidneys and diseases affecting them.  
The kidneys do much more than produce urine. They play essential roles in regulating fluid balance, electrolytes, acid-base balance, blood pressure, and the removal of waste products from the body.
Nephrologists diagnose and manage conditions including:

Acute kidney injury

Chronic kidney disease

Kidney failure

Electrolyte abnormalities

Acid-base disorders

Hypertension

Glomerular diseases

Dialysis-dependent kidney disease

Kidney transplant-related conditions

Disorders affecting renal function

Because kidney function interacts with virtually every organ system, nephrology remains closely connected to general internal medicine.

What Does a Nephrologist Do?

Nephrologists care for patients across both inpatient and outpatient settings.
In the hospital, they may be consulted for acute kidney injury, severe electrolyte disturbances, dialysis needs, difficult-to-control hypertension, acid-base abnormalities, or kidney complications occurring in critically ill patients.
In the outpatient setting, nephrologists may longitudinally manage chronic kidney disease, hypertension, dialysis patients, glomerular disease, or kidney transplant recipients.
The specialty can therefore involve both acute problem-solving and years-long relationships with patients.
  • The Pathway

How Do You Become a Nephrologist?

The typical pathway in the United States is:

4 Years

Medical School

3 Years

Internal Medicine Residency

2 Years

Nephrology Fellowship

Optional Additional Training

Transplant Nephrology, Interventional Nephrology, Critical Care, Glomerular Disease, Onco-Nephrology, or another focused area
General nephrology fellowship is typically two years. Physicians interested in further specialization may pursue additional training afterward.

What Is ENT Residency Like?

ENT residency is heavily surgical — and there is a simple reason: you cannot learn surgery from a textbook. Early training incorporates broader rotations and foundational clinical management before residents advance into increasingly complex ENT operations.

What Subspecialties Are Available in Nephrology?

Nephrology offers several opportunities for physicians who want to develop expertise in a particular area.

01

Transplant Nephrology

Focuses on the medical care of patients before and after kidney transplantation.

02

Interventional Nephrology

Adds a significant procedural component, particularly involving dialysis access.

03

Critical Care Nephrology

Combines advanced kidney expertise with the care of critically ill patients.

04

Glomerular Disease

Focuses on diseases affecting the kidney's glomeruli.

05

Onco-Nephrology

An evolving field focused on kidney disease and renal complications in patients with cancer.

These were among the advanced career paths discussed in The Long Haul’s nephrology interview.

What Is Transplant Nephrology?

Transplant nephrology is medical rather than surgical.
Transplant surgeons perform the actual kidney transplant operation. Transplant nephrologists manage the medical aspects of kidney transplantation.
Before transplantation, this can include evaluating patients with advanced kidney disease or those receiving dialysis to determine their candidacy for transplantation.
After transplantation, care can include:
  • Monitoring the transplanted kidney
  • Managing immunosuppressive medications
  • Monitoring kidney function
  • Managing hypertension and diabetes
  • Identifying infectious complications
  • Recognizing transplant-related complications
  • Providing long-term medical care after transplantation

What Procedures Do Nephrologists Perform?

Nephrology can offer procedural opportunities, particularly for physicians pursuing interventional nephrology.
Procedures may include:
  • Temporary dialysis catheter placement
  • Tunneled dialysis catheter placement
  • Management of arteriovenous fistulas
  • Management of arteriovenous grafts
  • Dialysis access troubleshooting
  • Thrombectomy for thrombosed dialysis access
  • Other procedures involving dialysis access
The amount of procedural work varies significantly depending on the nephrologist’s training and practice setting.

Why Choose Nephrology?

Nephrology can be particularly attractive to students who love physiology and complex medical problem-solving.
Kidney disease often requires physicians to understand how multiple physiological systems interact rather than simply treating an isolated organ.
Electrolyte abnormalities, fluid status, blood pressure, medications, cardiovascular disease, diabetes, infection, and other conditions may all need to be considered simultaneously.

A Physician's Path to Nephrology

For Dr. Mehta, the interest developed during Internal Medicine residency when one of his first attending physicians at the VA was a retired nephrologist.
As he gained more exposure, he found that he particularly enjoyed working through complex electrolyte abnormalities and solving the physiology behind them. That mentorship and early exposure helped shape his eventual specialty choice.

What Is Rewarding About Nephrology?

Nephrology gives physicians an opportunity to care for patients during some of the most consequential periods of their lives.
Patients with kidney failure may experience years of dialysis as well as significant cardiovascular, infectious, and other complications.
Kidney transplantation can dramatically alter that trajectory.
For transplant nephrologists, being able to follow a patient through transplantation and see the effect that a functioning transplanted kidney can have on that person’s life can be particularly meaningful.
“To bring that gift of a foreign organ to an individual and to change their life is what is rewarding about transplant medicine.”

What Is Challenging About Nephrology?

Nephrology patients can be extraordinarily medically complex.
Patients receiving dialysis or transplant care may also develop particularly strong longitudinal relationships with their nephrologists and sometimes view them almost as primary physicians.
As a result, nephrologists often continue to practice a significant amount of general internal medicine in addition to managing kidney disease.
In transplant nephrology, for example, a single patient visit can involve simultaneous management of:
  • Kidney allograft function
  • Immunosuppression
  • Hypertension
  • Diabetes
  • Infectious complications
  • Medication-related complications
  • Other transplant-related medical problems

What Does a Typical Day Look Like?

A nephrologist’s schedule depends heavily on practice setting.
In the physician interview, the academic transplant-nephrology schedule discussed was approximately 8 AM to 5 PM on regular days, with clinic during the week, transplant-related meetings, weekend coverage approximately every fifth weekend, and additional call responsibilities.
Individual schedules can vary substantially between private practice, academic medicine, general nephrology, transplant nephrology, and other practice models.

What Is the Lifestyle Like in Nephrology?

Nephrology can offer a mixture of scheduled outpatient work and more unpredictable inpatient or call responsibilities.
Lifestyle depends significantly on:
  • Practice type
  • Call schedule
  • Inpatient responsibilities
  • Dialysis coverage
  • Academic vs. private practice
  • Subspecialty
  • Group size
  • Geographic location
A primarily outpatient nephrologist may have a very different schedule from an academic transplant nephrologist or a physician who spends significant time covering hospitalized dialysis patients.

Can Nephrologists Work in Private Practice?

Nephrologists have several potential career settings, including:
  • Private practice
  • Academic medical centers
  • Hospitals and health systems
  • Dialysis-focused practices
  • Transplant centers
  • Research
  • Medical education
Private practice was described in the interview as a common career choice after fellowship and can offer opportunities for eventual partnership.
Academic medicine, meanwhile, can allow physicians to combine clinical care, teaching, and research.
  • Not exactly

Will I Only See Kidney Disease?

One of the interesting features of nephrology is the amount of general medicine involved.
Common underlying conditions such as hypertension, diabetes, and vascular disease are deeply intertwined with kidney disease.
At the same time, nephrologists may encounter unusual and highly complex renal pathology.
The interview describes experience practicing in rural Northern California and encountering unusual kidney pathology even after training at a major academic institution, illustrating that medically interesting cases aren’t limited to tertiary referral centers.

How Much Do Nephrologists Make?

Nephrologist compensation varies based on factors including:
  • Geographic location
  • Private practice vs. academic medicine
  • Years of experience
  • Productivity
  • Partnership opportunities
  • Call responsibilities
  • Subspecialization

Private practice can provide opportunities for partnership and additional income as physicians become established within a group.

Academic compensation structures differ and may incorporate productivity, academic promotion, research, and other responsibilities.

The physician interview discussed private-practice starting compensation of approximately $200,000 at the time of the conversation, but that number should not be presented as the current national average.

For every specialty page, current compensation information should be independently updated because physician salaries change over time.

What Are Common Misconceptions About Nephrology?

One misconception is that nephrologists simply manage kidney laboratory values and dialysis.

In reality, the specialty can involve substantial general internal medicine.

Dialysis and transplant patients frequently have multiple chronic diseases and complications requiring the nephrologist to think beyond an isolated kidney problem.

This can include hypertension, diabetes, cardiovascular disease, infections, medication management, and numerous other interconnected conditions.

Who Is a Good Fit for Nephrology?

Nephrology is particularly well suited to students who would rather understand and solve a complicated physiological problem than simply memorize an algorithm.

  • You may enjoy nephrology if you:
  • Love physiology
  • Enjoy complex problem-solving
  • Like understanding why laboratory abnormalities occur
  • Enjoy electrolytes and acid-base disorders
  • Like internal medicine
  • Are interested in teaching or research
  • Want opportunities for further subspecialization
  • Want longitudinal patient relationships
  • Enjoy caring for medically complex patients
  • Are interested in dialysis
  • Are interested in transplantation
  • Want both inpatient and outpatient opportunities
  • Enjoy intellectually challenging cases

What Advice Is There for Students Interested in Nephrology?

A major theme from the interview was the importance of understanding medicine rather than simply memorizing it.
Medical knowledge learned early in training can remain relevant many years later. Building a strong conceptual foundation can therefore be more valuable than studying solely to remember information long enough to pass an exam.
Curiosity also matters.
Students should feel comfortable asking questions, investigating things they don’t understand, and continuing to learn outside of formal lectures and rotations.
“Don’t be afraid to ask questions because I don’t think any question is a bad question.”

Another practical piece of advice from the interview is to continue reading throughout every stage of medical training.
Whether someone is an intern, resident, fellow, or attending, spending even 20–30 minutes each day reading about medicine can compound into an enormous amount of knowledge over an entire career.
  • FAQ

Frequently Asked Questions About Nephrology

Is nephrology a surgical specialty?

No. Nephrology is a medical subspecialty of internal medicine.

Even transplant nephrology is medical rather than surgical. Transplant surgeons perform the operation, while transplant nephrologists medically manage patients before and after kidney transplantation.

General nephrology fellowship is typically two years after completing an Internal Medicine residency. Additional training may be pursued for certain subspecialties.

Both.

Nephrologists can work in hospitals as consultants while also maintaining outpatient clinics and caring longitudinally for patients with chronic kidney disease, dialysis needs, hypertension, or kidney transplants.

Some do.

Procedural involvement varies by training and practice setting. Interventional nephrologists can perform procedures involving dialysis catheters, AV fistulas, AV grafts, thrombectomy, and other dialysis-access interventions.

No. Dialysis is an important component of nephrology, but the specialty encompasses acute kidney injury, chronic kidney disease, electrolyte abnormalities, hypertension, glomerular disease, transplantation, acid-base disorders, and many other conditions.
Yes. Potential areas include transplant nephrology, interventional nephrology, critical care nephrology, glomerular disease, and onco-nephrology.
It can be an excellent fit. Kidney medicine relies heavily on physiology, particularly fluid balance, electrolytes, acid-base disorders, blood pressure, and the relationships between different organ systems.
Yes. Private practice is a major career option, as is academic medicine.
Yes. Academic nephrologists may combine patient care with medical education, clinical research, basic science research, or other scholarly work.
Kidney function is interconnected with nearly every major physiological system. Nephrologists frequently manage patients with multiple simultaneous medical problems and must integrate laboratory findings, physiology, medications, fluid status, cardiovascular health, and other factors into their decision-making.
