Nephrology in Houston, TX.

It's done with local anesthetic and is generally well tolerated. You'll feel pressure rather than sharp pain, and there is often a loud click as the needle fires, which is expected and startles people who weren't warned. Soreness at the site for a few days afterward is normal.

Usually when the eGFR falls between 5 and 10 and symptoms appear: persistent nausea, fatigue, swelling, breathlessness, or confusion. The laboratory number alone does not decide it. How you feel matters more.

No. Fluid flowing in and out is not painful, though some patients notice a sensation of fullness. There are no needles.

No. The operation is performed at a partner transplant center. Everything else — the full pre-transplant evaluation, cardiac clearance, tissue typing, cancer screening, candidacy assessment, listing coordination, and all post-transplant medical management — is handled in-house at Remix Medical.

The hands-on training is delivered at a partner home dialysis unit by a home training nurse. Remix Medical evaluates your candidacy, selects the modality with you, manages your dialysis prescription and ongoing care, and treats complications throughout.

Not if your kidneys are healthy. In established chronic kidney disease, moderate protein around 0.8 g/kg is appropriate for most patients. Severe restriction slows progression only modestly and risks malnutrition, which is more dangerous.

Yes. Once you leave the transplant center, your care returns to us. We manage your immunosuppressive regimen, monitor drug levels, screen for rejection and infection, protect the graft, and treat the blood pressure, bone, diabetes, and cholesterol problems that come with long-term immunosuppression.

Because stone formation depends on how much of each substance passes through your urine across an entire day, including overnight when urine is most concentrated and crystals form most readily. A spot sample captures one moment and misses the mechanism.

No. Fistula and graft creation is performed by a vascular surgeon. Angioplasty, stenting, and declotting are performed by an interventional radiologist or vascular surgeon. Remix Medical evaluates the access, monitors maturation, identifies dysfunction, coordinates those referrals, and manages your dialysis care throughout.

Because albumin appears in the urine years before creatinine rises. By the time creatinine climbs, substantial kidney function has already been lost. The albumin-to-creatinine ratio finds damage while treatment still does the most good.

Hepcidin blocks iron absorption at the gut wall in chronic kidney disease, so oral iron frequently fails no matter how faithfully it is taken. Intravenous iron bypasses the gut entirely and reliably replenishes stores.

A measurement of how much urine remains in your bladder after you empty it. The probe is placed on your lower abdomen and the volume appears on the screen. It takes under two minutes, involves no catheter and no needle, and requires no preparation beyond arriving with a reasonably full bladder.

We perform the evaluation — determining whether a biopsy is indicated, confirming it is safe, correcting bleeding risk and blood pressure, and reviewing your imaging and medications. The biopsy itself is performed by an interventional radiologist under ultrasound guidance. We coordinate the procedure and interpret the pathology.

Office readings capture a single moment in an artificial setting. Ambulatory monitoring collects dozens of readings during ordinary activity and, critically, during sleep. It is the reference standard for diagnosing hypertension and the only way to measure the nighttime blood pressure pattern.

Once your eGFR falls below 20, before dialysis begins if possible. Transplanting before dialysis is called preemptive transplant and produces better outcomes than transplanting after years of dialysis. The most common reason patients miss this window is starting the conversation too late.

Yes. Automated peritoneal dialysis uses a cycler machine that performs the exchanges overnight. You connect before bed and disconnect in the morning, leaving your days free.

Because a fistula takes three to six months to mature. Placed early, it means you never need a catheter. Patients who arrive in an emergency room in fluid overload start dialysis through a neck catheter that afternoon, and carry that risk for months.

It requires more of you. Sterile technique in peritoneal dialysis and self-cannulation in home hemodialysis both take real training. Patients who are told it will be simple and then discover otherwise tend to quit. Patients who know what to expect generally do well.

Because dialysis itself removes amino acids. Protein requirements increase substantially once dialysis begins. Advice that was correct at stage 4 becomes incorrect at stage 5, and patients are rarely told that it changed.

Immediately before your morning dose, not after. This is called a trough level. A sample drawn even two hours after the dose is uninterpretable and can lead to a dangerous dose adjustment in the wrong direction.

No. Dividing albumin by creatinine corrects for how dilute or concentrated the sample is, so a single random void gives a reliable result. This is why the ratio replaced the 24-hour collection for screening.

Citrate is the body's natural stone inhibitor. It binds calcium in the urine so it cannot crystallize. Low urinary citrate is common in stone formers and is readily corrected with potassium citrate.

No. The mortality signal above 11 g/dL is why the target exists. If fatigue persists at target, the right response is to look for another cause rather than to raise the hemoglobin further.

A fistula has the lowest rates of infection and clotting and the longest survival. A tunneled catheter has infection rates several times higher and causes central veins to narrow, which forecloses future access options. A fistula requires three to six months to mature; a catheter works immediately, and that convenience is expensive.

Because a bladder that never empties backs pressure into the kidneys. That pressure damages the kidney's ability to concentrate urine, excrete potassium, and excrete acid. A rising creatinine, a high potassium, and a low bicarbonate can all come from a bladder that will not empty, and all three may reverse if the obstruction is relieved in time.

You will be asked not to eat solid food beforehand. Clear liquids are usually permitted closer to the procedure, and we give you specific instructions. Arriving dehydrated is not the goal, particularly when the main risk of the procedure is bleeding.

Blood pressure that is elevated in a medical setting but normal elsewhere. It affects roughly one in five people with high office readings. Identifying it prevents unnecessary medication and its side effects.

NSAIDs including ibuprofen and naproxen. Certain antibiotics. Contrast dye when the study is not necessary. Many over-the-counter and herbal products. Bring everything you take, including supplements, to every visit.

Age alone is rarely a barrier. Selected patients in their seventies and eighties are transplanted with good results. What matters is cardiovascular health, absence of active cancer, and the ability to manage a demanding medication regimen.

Many patients do both. Dialysis units arrange treatment at partner centers for travel. Home dialysis offers more schedule flexibility than in-center treatment.

The catheter heals for about two weeks, then training takes one to two weeks. That is far shorter than the three to six months a hemodialysis fistula requires to mature, which is why peritoneal dialysis is often the right choice when dialysis is needed sooner.

Usually not. Blanket potassium restriction is common and frequently overprescribed. It removes fiber, worsens acidosis, and pushes people toward processed food. Restriction should be based on your actual potassium level, not on a diagnosis.

Infection of the abdominal lining, and the principal risk of peritoneal dialysis. It comes almost entirely from breaks in sterile technique during an exchange, which is why training focuses on technique above everything else.

Many, including certain antibiotics, antifungals, calcium channel blockers, seizure medications, and grapefruit juice. Never start any medication, prescription or over-the-counter, without telling us first.

It has likely clotted. This is an emergency and hours matter. Go to an emergency department or contact us immediately. A fistula that is pulsatile rather than thrilling has usually developed an outflow stenosis.

Not necessarily. A dipstick detects total protein and is insensitive to the low albumin concentrations that matter most. A negative dipstick does not exclude moderately increased albuminuria. Ask whether an actual albumin-to-creatinine ratio was performed.

Because it determines which stone forms. Persistently acidic urine produces uric acid and cystine stones. Persistently alkaline urine produces calcium phosphate and struvite stones. This single value redirects the entire prevention strategy.

Transfusion sensitizes your immune system and raises your panel reactive antibody, which makes finding a compatible donor kidney significantly harder. This consideration is easy to overlook and costly to get wrong.

No. Ultrasound uses sound waves. There is no ionizing radiation and no contrast dye, which makes it safe in pregnancy and in patients whose kidney function would be threatened by CT contrast.

When the kidneys are small and scarred, the tissue will show fibrosis without revealing a cause. When the clinical picture already establishes the diagnosis — long-standing diabetes with retinopathy and slowly rising creatinine — the biopsy confirms what is already known.

Normal office readings with elevated pressures during daily life. It is more dangerous than white coat hypertension because the damage accumulates while the chart looks reassuring.

The slope of your eGFR over time tells us more than any single value. A patient stable at 35 for six years and a patient who fell from 55 to 35 in one year face entirely different situations and need entirely different plans.

No. Dialysis filters waste and removes fluid. It does not make erythropoietin, activate vitamin D, or regulate blood pressure and acid balance. Anemia, bone disease, and blood pressure still require separate treatment.

Many patients do. Years of exposure to dialysis fluid change the peritoneal membrane. This is an expected part of the course, not a failure, and the transition is planned rather than urgent.

Paired exchange programs match incompatible donor-recipient pairs into chains so that multiple transplants can proceed. For highly sensitized patients, desensitization protocols can make transplant possible where it otherwise would not be.

Immunosuppression raises skin cancer risk to many times that of the general population. Annual full-skin examination and strict sun protection are standard for every transplant recipient.

Processed food, restaurant meals, and bread. Not the salt shaker. Reading labels accomplishes far more than removing salt from the table. Watch for potassium chloride salt substitutes, which are the most frequently missed potassium source.

More easily than on in-center hemodialysis. Supplies ship ahead to your destination. This is one of the more common reasons patients choose a home modality.

An ultrasound performed about six weeks after fistula creation to assess diameter, flow, and depth beneath the skin. Roughly a third of fistulas never mature adequately. Finding that early allows salvage or a change of plan rather than a failed cannulation attempt.

Because fever, hard exercise, prolonged standing, urinary infection, and menstruation can all raise albumin temporarily. Persistent albuminuria requires two of three abnormal samples over three months before the diagnosis is made.

During an ordinary week. Not while traveling, not while ill, and not right after a holiday. The goal is your real chemistry, not a snapshot of an unusual few days.

Kidneys under about nine centimeters generally indicate long-standing, chronic damage rather than a recent injury. This finding often changes the workup: it makes reversible causes less likely and a kidney biopsy less useful.

Bleeding is the principal risk. Most bleeding is minor and self-limited. A small percentage of patients require transfusion, and a very small number require a procedure to stop the bleeding. Risk is reduced by controlling blood pressure and stopping anticoagulants beforehand, both of which we manage.

Most patients notice the overnight inflations. This is unavoidable and is also where the most valuable data comes from. Sleeping through it is not required for the readings to be valid.

For most patients who are candidates, yes — more years and better quality of life. Evaluation can begin before dialysis starts. Time spent on dialysis is itself a risk factor for how a transplanted kidney performs afterward.

Age alone does not disqualify anyone. What matters is vision, dexterity, cognition, and whether your home environment supports the treatment. Many older patients do home dialysis successfully.

Malnutrition in advanced kidney disease, and it independently predicts death. It happens when patients are told to avoid protein, potassium, phosphorus, and sodium simultaneously and simply stop eating. Every restriction carries a cost.

A virus that most people carry harmlessly and that reactivates under immunosuppression. It can quietly destroy a transplanted kidney. We screen for it by measuring viral load in the blood on a schedule, because by the time it causes symptoms the damage is done.

To confirm the treatment actually changed your urine chemistry. Stones take years to recur, so waiting for the next stone is a poor way to learn whether the treatment worked. This repeat collection is the one patients most often skip.

The access may be diverting blood from your hand, a condition called steal syndrome. It can progress to tissue loss. Cold, pale, painful, or weak hand on the access side needs urgent evaluation.

Yes. ACE inhibitors, ARBs, SGLT2 inhibitors, and finerenone all reduce it, and that reduction independently improves kidney and cardiovascular outcomes. The number is not only a marker; lowering it changes the trajectory.

Ultrasound reliably detects stones in the kidney and at the junction with the ureter, and detects the swelling caused by obstruction. Small stones in the mid-ureter can be missed. A CT scan is more sensitive when a ureteral stone is strongly suspected.

Pathology typically returns within seven to fourteen days. The tissue is examined by light microscopy, immunofluorescence, and electron microscopy, and all three are usually needed for a complete diagnosis.

No. The recorder is not waterproof. Shower before your appointment and again after you return the device.

Not rejection or infection. Patients stopping their medications or stopping their follow-up visits. The kidney depends on both continuing indefinitely.

Annually if you have diabetes or hypertension, and more often if albuminuria is already present or your eGFR is falling. Annual screening in diabetes is standard of care and is very frequently missed.

Because the veins in that arm are the raw material for your access, current or future. Every intravenous line, blood draw, and blood pressure cuff damages them. Protect the arm from the moment it is designated, which should be well before dialysis begins.

It confirms two kidneys are present, measures their size, and rules out cysts, masses, or obstruction. Biopsying a single kidney or a small scarred kidney carries different risks and often yields no useful information.

No. A percutaneous kidney biopsy is done with local anesthetic while you are awake. General anesthesia is not used. An open biopsy taken during unrelated abdominal surgery is possible but uncommon and is not how this is normally done.

A simple urine test measuring how much albumin is leaking into your urine — one of the earliest and most sensitive signs of kidney damage. Under 30 mg/g is normal. Between 30 and 300 indicates early kidney damage, which is where treatment does the most good and where patients feel nothing at all. Above 300 is severe.
