You have been advised to start dialysis, and suddenly your doctor is talking about a catheter, fistula, or vascular access. You may wonder why a kidney specialist is involved in a procedure that seems unrelated to kidney function itself.
The answer is simple: safe and reliable access to your bloodstream can be an important part of dialysis care.
Interventional nephrology combines kidney expertise with selected minimally invasive procedures used to support patients with kidney disease and dialysis needs.
Interventional nephrology focuses on procedures related to kidney care, particularly those involving vascular access for dialysis.
Depending on the patient's situation and available services, this may include assessment and management of dialysis access, placement of temporary or tunneled dialysis catheters, and procedures to identify or address access-related problems.
The exact procedure depends on the patient's medical condition and the type of dialysis being planned.
Haemodialysis requires a way to remove blood from the body, pass it through a dialysis filter, and return it safely.
There are several types of vascular access, including:
Arteriovenous fistula
Arteriovenous graft
Temporary dialysis catheter
Tunneled dialysis catheter
Each has different benefits, limitations, and expected uses.
If you already have dialysis access, changes such as swelling, redness, bleeding, pain, fever, poor blood flow, or unusual changes in the access site should be reported promptly to your medical team.
A poorly functioning access can interfere with dialysis and may require assessment.
One misconception is that vascular access only needs attention after dialysis has already started.
In some patients with advanced chronic kidney disease, planning ahead can provide time to discuss the most appropriate access option and allow preparation before it becomes urgently necessary.
However, the timing depends on the expected progression of kidney disease and the patient's individual circumstances.
India's need for dialysis services continues to be substantial.
The Ministry of Health and Family Welfare reported that by October 2024, the Pradhan Mantri National Dialysis Programme had 1,542 dialysis centres across 36 States/UTs, with more than 25 lakh patients having availed services under the programme.
With a large number of people requiring dialysis, maintaining dependable vascular access is an important part of delivering ongoing treatment.
A common belief is: “If dialysis is working, the access doesn't need much attention.”
Actually, access deserves regular attention precisely because dialysis depends on it.
A patient can otherwise feel well while an access problem is developing. Changes in blood flow, repeated clotting, infection, or narrowing may affect how effectively dialysis can be delivered.
The dialysis team should therefore be told about unusual changes rather than waiting for the access to fail completely.
Consider a patient who has been receiving haemodialysis and notices that the dialysis team is having increasing difficulty obtaining the expected blood flow from the access.
Instead of repeatedly continuing treatment without investigating the problem, the access can be assessed to determine what may be causing the reduced performance. Early attention may help identify an access complication before it becomes a larger interruption to dialysis care.
The lesson is straightforward: a dialysis machine can only work effectively when the access supporting it is functioning properly.
The procedure depends on what is required.
Some vascular-access procedures can be performed using local anaesthesia and image guidance. The medical team assesses the patient's medical history, blood tests, medications, infection risk, and other factors before deciding whether a procedure is appropriate.
Patients should receive clear instructions about medicines, food, and aftercare based on the specific procedure being planned.
Interventional and kidney-care services may include:
Dialysis vascular access management
Dialysis catheter placement
Dialysis catheter-related care
Arteriovenous fistula assessment
Arteriovenous graft assessment
Dialysis access complication management
Chronic Kidney Disease
Acute Kidney Injury
Dialysis care
Electrolyte management
Critical care nephrology
Kidney transplant evaluation
At स्वस्थ Kidney Clinic, we focus on connecting the procedure with the patient's wider kidney-care needs. Our approach includes reviewing kidney function, dialysis requirements, existing vascular access, medical history, and treatment goals so that patients understand why a particular intervention may be recommended and what follow-up may involve.
Having a procedure does not mean access care is finished.
Patients should follow their medical team's instructions regarding wound care, activity, medicines, and monitoring. Any significant bleeding, fever, increasing pain, swelling, redness, or change in dialysis access function should be reported promptly.
Regular assessment can help identify potential problems before they interfere significantly with dialysis.
An interventional nephrologist specialises in selected minimally invasive procedures connected with kidney care, particularly dialysis vascular-access procedures.
Haemodialysis may use an arteriovenous fistula, arteriovenous graft, or dialysis catheter. The appropriate option depends on the patient's medical circumstances and dialysis needs.
Yes. Dialysis catheters can be associated with infection and other complications. Fever, chills, redness, drainage, or other concerning symptoms should be reported promptly to the treating medical team.
If you are preparing for dialysis or experiencing problems with existing dialysis access, don't wait until treatment becomes difficult or impossible.
