Causes & Risk Factors
Several factors can contribute to Chronic Renal Failure (Stage 5) on Dialysis.
End-stage renal disease develops when the kidneys sustain irreversible damage over time, typically through years of progressive disease.
End-stage renal disease develops when the kidneys sustain irreversible damage over time, typically through years of progressive disease. The most common culprit is diabetes mellitus, which damages the tiny blood vessels in the kidneys through consistently high blood sugar levels. High blood pressure ranks as the second leading cause, creating excessive pressure that gradually destroys the kidney's filtering units called nephrons.
Other significant causes include polycystic kidney disease, an inherited condition where fluid-filled cysts gradually replace normal kidney tissue.
Other significant causes include polycystic kidney disease, an inherited condition where fluid-filled cysts gradually replace normal kidney tissue. Glomerulonephritis, inflammation of the kidney's filtering units, can result from infections, autoimmune diseases, or unknown causes. Certain medications, particularly long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), can cause irreversible kidney damage.
Less common causes include lupus nephritis, kidney stones that cause repeated blockages, inherited conditions like Alport syndrome, and exposure to certain toxins or drugs.
Less common causes include lupus nephritis, kidney stones that cause repeated blockages, inherited conditions like Alport syndrome, and exposure to certain toxins or drugs. Sometimes, acute kidney injury from severe illness, major surgery, or medication reactions can progress to chronic kidney failure if the initial damage is extensive enough to prevent recovery.
Risk Factors
- Diabetes mellitus (Type 1 or Type 2)
- High blood pressure (hypertension) for many years
- Family history of kidney disease or genetic conditions
- Age over 60 years
- African American, Native American, or Hispanic ethnicity
- Heart disease or history of stroke
- Long-term use of NSAIDs or certain medications
- Obesity and metabolic syndrome
- Smoking tobacco products
- History of acute kidney injury
Diagnosis
How healthcare professionals diagnose Chronic Renal Failure (Stage 5) on Dialysis:
- 1
Diagnosing stage 5 chronic kidney disease involves comprehensive blood and urine tests that reveal severely reduced kidney function.
Diagnosing stage 5 chronic kidney disease involves comprehensive blood and urine tests that reveal severely reduced kidney function. The estimated glomerular filtration rate (eGFR), calculated from blood creatinine levels, typically measures below 15 mL/min/1.73m² in stage 5 disease. Blood urea nitrogen (BUN) and creatinine levels are significantly elevated, indicating the kidneys can't effectively remove these waste products.

Additional tests help assess complications and plan treatment.
Additional tests help assess complications and plan treatment. These include electrolyte panels showing imbalances in sodium, potassium, and phosphorus, complete blood counts revealing anemia, and parathyroid hormone levels indicating bone metabolism problems. Urine tests may show persistent protein or blood, though urine output often decreases substantially in stage 5 disease.

Imaging studies like kidney ultrasounds typically reveal small, scarred kidneys, though some conditions like polycystic kidney disease show enlarged kidneys.
Imaging studies like kidney ultrasounds typically reveal small, scarred kidneys, though some conditions like polycystic kidney disease show enlarged kidneys. Sometimes kidney biopsies were performed earlier in the disease course to determine the underlying cause, but they're rarely needed once stage 5 is reached. The focus shifts from diagnosis to preparing for renal replacement therapy and managing complications.
Complications
- Stage 5 kidney disease affects virtually every body system, creating multiple complications that require careful management.
- Cardiovascular disease becomes the leading cause of death, with heart attacks, strokes, and heart failure occurring at much higher rates than in the general population.
- Mineral and bone disorders develop as kidneys lose their ability to activate vitamin D and regulate phosphorus, leading to weak bones, fractures, and calcium deposits in blood vessels.
- Anemia develops in most patients as kidneys produce less erythropoietin, the hormone that stimulates red blood cell production.
- This causes severe fatigue and can worsen heart problems.
- Fluid overload leads to high blood pressure, shortness of breath, and swelling throughout the body.
- Electrolyte imbalances, particularly high potassium levels, can cause dangerous heart rhythm abnormalities requiring emergency treatment.
- Uremic toxins build up in the blood, causing nausea, confusion, and eventually coma without dialysis treatment.
Prevention
- Preventing progression to stage 5 kidney disease requires early detection and aggressive management of underlying conditions.
- For people with diabetes, maintaining blood sugar levels as close to normal as possible significantly slows kidney damage progression.
- Regular monitoring with hemoglobin A1C tests and working closely with diabetes specialists helps optimize blood sugar control.
- Controlling blood pressure to target levels below 130/80 mmHg, or even lower in some cases, protects remaining kidney function.
- ACE inhibitors or ARB medications provide additional kidney protection beyond blood pressure lowering.
- Regular exercise, maintaining healthy weight, and following heart-healthy diets support both kidney and cardiovascular health.
- Once someone reaches stage 4 or 5 kidney disease, prevention focuses on slowing further decline and preparing for renal replacement therapy.
- This includes: - Avoiding nephrotoxic medications when possible - Staying well-hydrated unless fluid restrictions apply - Managing complications like anemia and bone disease - Getting vaccinated against preventable infections - Creating vascular access for future dialysis needs.
- Early nephrology referral and comprehensive pre-dialysis education help patients make informed treatment decisions.
Treatment for stage 5 chronic kidney disease centers on renal replacement therapy - either dialysis or kidney transplantation.
Treatment for stage 5 chronic kidney disease centers on renal replacement therapy - either dialysis or kidney transplantation. Hemodialysis, performed three times weekly at dialysis centers, uses a machine to filter blood through an artificial kidney. Each session lasts 3-4 hours, requiring vascular access through an arteriovenous fistula, graft, or catheter. Peritoneal dialysis offers an alternative, using the patient's abdominal lining as a natural filter, allowing treatments at home with more flexible scheduling.
Kidney transplantation provides the best long-term outcomes when suitable donors are available and patients meet transplant criteria.
Kidney transplantation provides the best long-term outcomes when suitable donors are available and patients meet transplant criteria. Living donor transplants generally offer better results than deceased donor organs, though waiting lists for deceased donor kidneys can extend several years. Pre-transplant evaluation includes extensive medical, psychological, and social assessments.
Supportive medications manage complications and improve quality of life.
Supportive medications manage complications and improve quality of life. These include: - Phosphate binders to prevent bone disease - Iron supplements and erythropoietin-stimulating agents for anemia - Blood pressure medications - Vitamin D supplements - Medications for mineral and bone disorders. Dietary modifications restrict protein, phosphorus, potassium, and sodium while ensuring adequate nutrition.
Emerging treatments show promise, including more biocompatible dialysis membranes, wearable artificial kidneys, and regenerative medicine approaches.
Emerging treatments show promise, including more biocompatible dialysis membranes, wearable artificial kidneys, and regenerative medicine approaches. Home hemodialysis programs are expanding, offering patients more flexibility and potentially better outcomes than traditional in-center treatments. Research continues into artificial kidney devices that could eventually replace traditional dialysis.
Living With Chronic Renal Failure (Stage 5) on Dialysis
Successfully living with stage 5 kidney disease on dialysis requires adapting daily routines around treatment schedules while maintaining quality of life. Hemodialysis patients typically arrange their work, travel, and social activities around their three-weekly treatment schedule, though many continue working full-time or part-time jobs. Peritoneal dialysis offers more scheduling flexibility, with exchanges performed at home throughout the day or overnight while sleeping.
