When the kidneys cannot adequately remove waste products and excess fluid from the blood, dialysis may be needed to support essential body functions. It is commonly used in advanced chronic kidney disease and kidney failure, and may also be required temporarily in certain cases of acute kidney injury. The timing and type of dialysis depend on kidney function, symptoms and the patient's overall medical condition.
At Sterling Hospitals, Vadodara, patients can access dialysis and specialised nephrology care, including haemodialysis, peritoneal dialysis and continuous renal replacement therapy (CRRT). The nephrology team evaluates each patient's condition to determine the appropriate treatment approach and provide ongoing monitoring based on individual clinical needs.
Kidney dialysis is a life-supporting medical treatment that takes over the filtering functions of the kidneys when they can no longer work adequately on their own. Healthy kidneys continuously filter the blood, regulate fluid levels, and maintain chemical and electrolyte balance. When this function declines significantly, toxins, waste products, and excess fluids accumulate in the body, which can disrupt normal physiological processes.
Dialysis helps manage this imbalance by artificially removing waste products and excess fluid from the bloodstream. However, it is important to understand that dialysis acts as a substitute treatment; it does not cure underlying kidney disease or fully replace all complex biological functions of healthy kidneys. Depending on the severity and cause of the dysfunction, dialysis may be prescribed as a temporary measure during acute illness or as an ongoing, long-term therapy for chronic conditions.
Dialysis may be recommended when the kidneys can no longer maintain an adequate balance of waste products, fluids and electrolytes. The decision is based on the patient's symptoms, blood test results, fluid status and overall clinical condition rather than a single kidney function measurement.
Chronic kidney disease (CKD) develops when kidney function or structure remains abnormal over an extended period. In advanced CKD, the kidneys may lose much of their ability to filter waste and remove excess fluid. Dialysis may be required when kidney function becomes severely impaired and medical management alone is no longer sufficient to control the resulting complications.
Not everyone with advanced CKD requires immediate dialysis. A nephrologist monitors kidney function and symptoms to determine when renal replacement therapy becomes necessary.
Acute kidney injury (AKI) involves a sudden decline in kidney function. It may occur due to severe infection, dehydration, certain medications, reduced blood supply to the kidneys or other medical conditions.
Dialysis may be required if acute kidney injury causes severe fluid overload, dangerous electrolyte disturbances, significant acid-base imbalance or the accumulation of waste products that cannot be adequately managed through other treatments. Depending on the cause, kidney function may recover, allowing dialysis to be discontinued.
Dialysis may be recommended when kidney failure leads to complications that cannot be controlled adequately with medication or other measures. These may include:
Symptoms that may occur when kidney function deteriorates include:
These symptoms do not automatically mean that dialysis is required, as they may have other causes. However, they warrant medical evaluation, particularly in people with known kidney disease. Severe breathlessness, confusion, chest pain or other signs of a medical emergency require immediate assessment.
The type of dialysis recommended depends on the patient's kidney function, medical condition, treatment requirements and suitability for different methods. The main approaches include haemodialysis, peritoneal dialysis and continuous renal replacement therapy.
Haemodialysis uses a dialysis machine and a specialised filter called a dialyser to remove waste products and excess fluid from the blood.
During treatment, blood is drawn from the body through a vascular access, passed through the dialyser and returned to the bloodstream after filtration. The machine and dialysis solution help remove waste products and excess fluid while supporting the body's electrolyte balance.
Haemodialysis is commonly used for patients with advanced chronic kidney disease or kidney failure. It may also be performed in acute situations when rapid removal of waste products or fluid is required.
For patients receiving maintenance haemodialysis, treatment is generally scheduled several times a week. The frequency and duration of each session depend on the patient's clinical needs and the nephrologist's treatment plan.
Peritoneal dialysis uses the peritoneum, the membrane lining the abdominal cavity, as a natural filter to remove waste products and excess fluid from the blood.
A dialysis solution is introduced into the abdominal cavity through a catheter. Waste products and excess fluid move from the blood vessels in the peritoneum into the solution, which is subsequently drained and replaced.
Peritoneal dialysis may be performed manually at intervals throughout the day or with the help of a machine, usually overnight. Continuous Ambulatory Peritoneal Dialysis (CAPD) is one form of this treatment.
This approach may be suitable for selected patients who prefer or are medically appropriate for home-based dialysis. It requires training, appropriate home conditions and careful adherence to hygiene procedures to reduce the risk of infection.
Continuous Renal Replacement Therapy is a form of dialysis primarily used for critically ill patients, particularly those with acute kidney injury who may not tolerate conventional haemodialysis.
CRRT removes waste products and excess fluid gradually over an extended period. This slower process can be useful for patients whose blood pressure or overall condition makes intermittent dialysis difficult to tolerate.
It may be considered in selected cases involving severe kidney dysfunction, fluid overload, sepsis or multiple organ dysfunction. The decision to use CRRT depends on the patient's condition and the requirements of critical care.
Dialysis helps manage the consequences of severely impaired kidney function by removing waste products and excess fluid from the body. Although it does not cure chronic kidney disease, it can help control complications and support essential body functions when the kidneys are unable to do so adequately.
The potential benefits include:
The extent of these benefits depends on the underlying kidney condition, the patient's overall health and the effectiveness of the treatment plan. Dialysis is usually combined with medical monitoring, dietary guidance, medication and management of other health conditions.
The nephrology team evaluates the patient's symptoms, medical history, existing conditions and kidney function before recommending dialysis. The assessment helps determine whether dialysis is necessary, which method is appropriate and how frequently treatment may be required.
Investigations may include:
For patients starting haemodialysis, the team assesses the available vascular access. This may involve a temporary dialysis catheter when treatment is urgent or a more permanent access, such as an arteriovenous fistula, for suitable patients requiring long-term treatment.
Patients considering peritoneal dialysis undergo an assessment to determine their suitability and receive guidance on catheter care, treatment procedures and infection prevention.
The team also reviews current medications, allergies, dietary requirements and other medical conditions. Patients should inform the treating team about all medicines and supplements they take.
The procedure varies according to the type of dialysis being performed.
During haemodialysis, the patient receives treatment via a dialysis machine that channels blood through a specialised filter called a dialyser. Blood circulates through the dialyser, where waste products and excess fluid are removed before the blood returns to the body. Blood pressure, heart rate and other relevant parameters are monitored during treatment.
A haemodialysis session commonly lasts around three to five hours, although the duration may vary according to the patient's needs and prescribed treatment plan.
During peritoneal dialysis, a dialysis solution is introduced into the abdominal cavity through a catheter. The solution remains inside for a prescribed period, allowing waste products and excess fluid to move into it. The solution is then drained and replaced according to the treatment schedule.
During CRRT, blood passes through a specialised filtration system continuously or for extended periods. The treatment is generally administered in a critical care setting, with close monitoring of fluid balance, blood pressure and laboratory parameters.
The nephrology team adjusts the treatment according to the patient's response and clinical requirements.
After haemodialysis, the patient is assessed for symptoms such as dizziness, weakness, muscle cramps or changes in blood pressure. The vascular access site is checked, and the team provides instructions on its care.
Patients receiving peritoneal dialysis follow a prescribed schedule and must maintain careful catheter hygiene. They are advised to monitor for symptoms such as abdominal pain, fever or cloudy drained fluid, which may indicate an infection requiring prompt medical assessment.
Patients undergoing CRRT are monitored according to their critical care needs. The medical team assesses kidney function, fluid balance and laboratory results to determine whether treatment should continue, be adjusted or be discontinued.
Ongoing care may include regular blood tests, medication reviews, dietary guidance and fluid intake recommendations. Patients should follow the prescribed dialysis schedule and consult their nephrologist before making changes to their treatment, diet or fluid intake.
Dialysis is an established treatment for kidney failure, but it can cause complications. The risks vary according to the type of dialysis, the patient's health and the presence of other medical conditions.
Possible complications include:
The likelihood of complications can be influenced by the patient's condition, dialysis prescription, vascular or catheter access and response to treatment.
At Sterling Hospitals, Vadodara, the nephrology team evaluates patients before treatment and monitors their response to dialysis. Patients are advised to report symptoms such as fever, chills, persistent dizziness, unusual bleeding, abdominal pain or problems with their dialysis access promptly so that they can be assessed.
The cost of kidney dialysis in Vadodara depends on the type of dialysis, the frequency and duration of treatment, the patient's medical condition and the level of monitoring required.
Haemodialysis, peritoneal dialysis and CRRT involve different equipment, consumables and clinical requirements. The overall cost may also vary between a single dialysis session, an ongoing treatment plan and dialysis required during hospitalisation for an acute medical condition.
Factors that may influence the total cost include:
Patients requiring maintenance haemodialysis may incur recurring costs because treatment is usually needed on a regular schedule. The cost of peritoneal dialysis may depend on the supplies required and the prescribed treatment regimen, while CRRT costs depend on the duration of treatment and the level of critical care required.
For an estimate, patients or their families can contact Sterling Hospitals, Vadodara. The hospital team can provide information about the expected charges based on the recommended treatment, clinical requirements and anticipated duration of care.

Kidney dialysis is a treatment that removes waste products and excess fluid from the blood when the kidneys cannot perform these functions adequately. It also helps manage certain electrolyte and acid-base imbalances. Dialysis may be required temporarily in acute kidney injury or as ongoing treatment in advanced kidney failure.
Dialysis may be needed when the kidneys can no longer adequately remove waste products and excess fluid or maintain a safe balance of electrolytes. It may be recommended in advanced chronic kidney disease, kidney failure or certain cases of acute kidney injury. The decision depends on symptoms, blood test results, fluid balance and the patient's overall condition.
The main types are haemodialysis, peritoneal dialysis and continuous renal replacement therapy (CRRT). Haemodialysis uses a machine and filter to clean the blood, while peritoneal dialysis uses the lining of the abdominal cavity as a natural filter. CRRT provides continuous or extended filtration and is mainly used for selected critically ill patients.
A conventional haemodialysis session commonly lasts around three to five hours, although the duration varies according to the patient's treatment requirements. Peritoneal dialysis follows a different schedule and may involve several exchanges throughout the day or automated treatment overnight. CRRT is generally performed continuously or for extended periods in a critical care setting.
Not always. Patients with acute kidney injury may need dialysis temporarily while their kidneys recover. In advanced chronic kidney disease or irreversible kidney failure, dialysis may be required over the long term unless a suitable alternative, such as kidney transplantation, becomes possible. The duration depends on the underlying condition and the recovery of kidney function.
Dialysis itself is not usually painful, although some patients may experience discomfort when needles are inserted for haemodialysis. Other possible symptoms during or after treatment include low blood pressure, muscle cramps, dizziness and fatigue. Patients should inform the dialysis team about any discomfort or symptoms so that the treatment can be reviewed.
Possible side effects include low blood pressure, muscle cramps, fatigue, nausea and changes in electrolyte levels. Patients may also develop complications involving the dialysis access, including bleeding or infection. The type and likelihood of side effects depend on the dialysis method and the patient's overall health.
Many people continue working, studying and participating in everyday activities while receiving dialysis. However, treatment requires regular sessions or daily exchanges, along with medication, dietary guidance and fluid management. The extent to which daily routines can be maintained depends on the patient's health, treatment schedule and response to dialysis.
The cost depends on the type of dialysis, the number and duration of sessions, consumables, investigations, medicines and any additional care required. Patients undergoing dialysis during hospitalisation may also incur charges for nursing, room facilities or critical care. Contact Sterling Hospitals, Vadodara, for an estimate based on the prescribed treatment plan.
Dialysis may be discontinued if it is required temporarily and the kidneys recover sufficiently to maintain essential functions. However, patients with irreversible kidney failure generally need ongoing dialysis unless they receive an alternative treatment, such as a kidney transplant. Any decision to stop or modify dialysis must be made by the treating nephrologist based on clinical assessment.
Patients should follow the instructions provided by their nephrology team regarding medicines, food and fluid intake. They may be asked to monitor their weight, blood pressure or fluid-related symptoms and should inform the team about any recent illness, fever, bleeding or access-site problems. Patients should not independently skip dialysis or change prescribed medication.
Urgent medical assessment is required for severe breathlessness, chest pain, confusion, fainting, uncontrolled bleeding or other sudden or severe symptoms. Fever or chills, redness or discharge around a dialysis access site, severe abdominal pain during peritoneal dialysis or cloudy drained fluid also require prompt medical attention. Patients should follow their treating team's emergency instructions.
