A health care provider may per chance well refer somebody to a nephrologist if they assume that the actual person displays indicators of kidney concerns, comparable to kidney disease, infections, or growths.

Listed here, we focus on what nephrologists build, the categories of situations they take care of, the procedures they design, and when somebody may per chance well should always seek the recommendation of with one.

What’s a nephrologist?

a doctor who is also a nephrologist

A nephrologist makes a speciality of treating diseases of the kidneys.

A nephrologist is a kidney specialist. They may be able to design diagnostic assessments and take care of situations linked to the kidneys.

Nephrology is a subspecialty of inner treatment. To turn precise into a nephrologist, an particular person should always serene:

  • entire an undergraduate and medical stage
  • entire a 3 year residency in traditional inner treatment practicing
  • entire a 2 or 3 year fellowship specializing in nephrology
  • trip a board certification examination (no longer mandatory)

Nephrologists incessantly work in particular person or neighborhood practices caring for folks referred from household doctors or specialists. Many nephrologists moreover seek the recommendation of on circumstances in hospitals and oversee dialysis items, incessantly in a sanatorium or a effectively being facility.

Some nephrologists moreover focal point on clinical analysis, while others work as professors and supervisors.

Which medical situations build they take care of?

Nephrologists take care of situations that involve or impact the kidneys, each straight and no longer straight.

Some general situations a nephrologist treats or helps take care of consist of:

  • superior or chronic kidney disease
  • glomerular situations, comparable to glomerulonephritis and nephrotic syndrome
  • tubulointerstitial kidney diseases
  • tubular defects
  • kidney vascular situations, comparable to renal artery stenosis
  • kidney infections
  • kidney neoplasms, or irregular growths
  • structural or functional abnormalities of the kidney, bladder, or urine series scheme, comparable to nephrolithiasis
  • high blood power
  • vasculitis
  • autoimmune situations titillating the kidneys
  • electrolyte, fluid, and acid-putrid imbalances or disturbances
  • some metabolic concerns, comparable to diabetes

What procedures build they design?

A blood take a look at is one process that a nephrologist may per chance well design.

Their practicing in inner treatment and nephrology permits nephrologists to design a in actuality long checklist of assessments, procedures, and therapies.

On the other hand, essentially the most general assessments they exhaust to diagnose or track kidney situations are blood and urine assessments.

The kidneys filter extra fluid and destroy from the blood, growing urine. This methodology that blood and urine assessments can incessantly show whether or no longer the kidneys are working wisely.

Urine assessments can moreover test for irregular stages of proteins linked to kidney damage within the urine.

The next sections focus on all these take a look at in additional detail.

Blood assessments

Overall blood assessments consist of:

Serum creatinine

The body produces creatinine as a byproduct of day-to-day muscle damage.

On the other hand, having high stages of creatinine within the blood, or elevated serum creatinine, can even be a imprint of innovative kidney disease.

Serum creatinine stages rely on components including age, body dimension, and plug. A fee of elevated than 1.2 for females or elevated than 1.4 for males may per chance well signal kidney concerns.

Glomerular filtration rate

The glomerular filtration rate (GFR) assessments how effectively the kidneys are ready to filter extra fluid and destroy from the blood. Nephrologists can resolve this fee by calculating the serum creatinine stage and factoring in age, sex, and plug.

Rate usually decreases with age, but famous GFR values consist of:

  • 90 or above (identical old)
  • 60 or below (kidney dysfunction)
  • 15 or below (high threat of desiring dialysis or a transplant for kidney failure)

Blood urea nitrogen

Urea nitrogen is a destroy product from the body breaking down protein in meals and drinks. Normally, blood urea nitrogen (BUN) stages elevate with reducing kidney characteristic.

Normally, BUN stages range from 7 to 20.

Urine assessments

Overall urine assessments consist of:


To design a urine analysis, or urinalysis, a nephrologist will incessantly ogle at a urine sample beneath a microscope to test for abnormalities.

Urinalysis can moreover involve a dipstick take a look at, for the length of which a nephrologist will dip a tiny, chemically treated strip precise into a urine sample. The strip will commerce color if it reacts with irregular protein stages, blood, bacteria, sugar, or pus.

This helps detect many kidney and urinary tract situations.

24 hour urine take a look at

In a 24 hour urine take a look at, an particular person will receive their urine for 24 hours to point out how unprecedented urine the kidneys can construct and the absolute top scheme unprecedented protein and electrolytes the kidneys leak into urine day to day.

Creatinine clearance

A creatine clearance take a look at compares the amount of creatinine in a 24 hour urine sample with that in blood samples to resolve how unprecedented destroy the kidneys are filtering every minute.


A microalbuminuria take a look at is a sexy form of dipstick take a look at that can defend shut up tiny amounts of the protein albumin in urine.

Other folks at chance of kidney situations, including these with high blood power or metabolic situations comparable to diabetes, may per chance well endure this take a look at if their fashioned dipstick take a look at is destructive for added protein stages within the blood (proteinuria).

Clinical procedures

Nephrologists exhaust several kinds of process to assist diagnose, track, and take care of kidney situations. These procedures consist of:


Ultrasound makes exhaust of sound waves to manufacture an image of the kidneys. This take a look at can detect adjustments within the dimensions or region of the kidneys, as effectively as any obstructions.

Obstructions can defend shut the salvage of tumors, other irregular growths comparable to cysts, or kidney stones.

CT scan

A CT scan makes exhaust of X-rays to manufacture an image of the kidneys, infrequently with the assist of an intravenous disagreement dye. This take a look at can detect obstructions or abnormalities in structure.

On the other hand, disagreement dyes will most likely be problematic for folks with kidney situations.


A biopsy entails inserting a thin needle that has a lowering edge to defend shut tiny slices of kidney tissues so that a healthcare reliable can mediate them.

A nephrologist may per chance well design a biopsy for just a few particular causes, usually to:

  • assess kidney damage
  • title a disease process and be taught the absolute top scheme it may per chance retort to remedy
  • assist realize transplant concerns


Hemodialysis entails running blood thru an synthetic kidney machine called a hemodialyzer to defend shut away destroy, extra fluid, and additional chemical substances ahead of returning it to the body. The blood will return to the body thru a port, or catheter, within the arm, leg, or infrequently neck.

Hemodialysis usually treats slay stage kidney failure, which occurs when the kidneys dangle lost round 85–90% of fashioned characteristic and dangle a GFR rate of beneath 15.

Other folks incessantly require 4 hour lessons thrice weekly. A nephrologist will incessantly oversee these lessons.

Kidney transplant

A transplant entails eradicating a share or all of a damaged kidney and changing it with a matching donor organ.

Surgeons design transplant procedures, but nephrologists many times work with the next care personnel to assist e book contributors thru the process.

When to ogle a nephrologist

A household or emergency doctor may per chance well refer somebody with indicators or symptoms of chronic, moderate, or severe kidney dysfunction to a nephrologist. They will incessantly refer infants born with kidney dysfunction to a nephrologist straight away.

Some general indicators and symptoms of severe kidney concerns consist of:

  • swelling, incessantly within the legs, ankles, or toes
  • complications
  • itchiness
  • nausea
  • diminished sense of taste and wander for food
  • unintended weight reduction
  • diminished urine output no longer linked to dehydration
  • unexplained confusion, memory concerns, or be troubled focusing
  • effort, fluid within the joints, or stiffness

  • unexplained blood power concerns

A health care provider may per chance also refer somebody to a nephrologist if they dangle got a medical condition that will increase their threat of kidney situations. Overall medical threat components for kidney situations consist of:

  • metabolic situations comparable to diabetes
  • high blood power
  • coronary heart situations

Nephrologists vs. urologists

Many defend shut into consideration urology a surgical speciality, and most urologists focal point on one or more major subspecialties, comparable to:

  • urologic oncology (urinary tract cancers)
  • pediatric urology (kid’s urinary tract situations)
  • kidney transplants
  • urinary tract stones
  • female urology
  • male infertility
  • erectile dysfunction
  • neurology (anxious scheme control or urinary tract and genitals)

Urologists and nephrologists infrequently work together, given the overlap of their speciality organs and bodily programs, and urologists are infrequently heavily occupied with kidney transplant surgical procedures.

Nephrologists and urologists moreover many times work together in circumstances titillating components comparable to habitual kidney or urinary tract stones or infections.


Nephrologists are doctors who focal point on situations titillating or impacting the kidneys.

They incessantly assist diagnose, track, and take care of moderate-to-severe kidney situations or assist contributors at chance of establishing kidney situations to govern their threat.

A pediatrician, household doctor, or emergency room doctor will incessantly refer contributors they mediate may per chance well dangle kidney concerns to a nephrologist.

How long somebody stays beneath the care of a nephrologist will rely on several components — most significantly, the severity of the kidney dysfunction or damage.

As an instance, contributors with severe or chronic kidney situations may per chance well require long wander care, whereas contributors with moderate situations may per chance well easiest require snappy care.
