Is dialysis needed if creatinine levels are more than 500?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My grandma's doctor referred her to see a nephrologist due to her elevated creatinine level, which is above 500 µmol/L. Do you think she will need to undergo dialysis?

Please guide.

Hi,

Welcome to icliniq.com.

I read your query and understand your concerns.

A creatinine level greater than 500 micromoles per liter (approximately 5.6 milligrams per deciliter) indicates that your grandmother has severely reduced kidney function, likely due to advanced chronic kidney disease (CKD stage 5) or possibly acute kidney injury on top of existing CKD.

Determining whether your grandmother needs dialysis immediately involves several factors beyond just the creatinine level. We typically assess the patient's symptoms, which may include nausea, vomiting, poor appetite, breathlessness, swelling, confusion, itching, or extreme fatigue.

We also look at electrolyte levels, particularly potassium; very high potassium levels may necessitate urgent dialysis. Additionally, we evaluate fluid status, uncontrolled swelling, or fluid accumulation in the lungs, despite medication, which raises concern.

Acidosis is another consideration, as we examine blood bicarbonate levels or arterial blood gas results. Finally, we assess the trend in creatinine levels to determine whether it is rapidly worsening or has remained stable for a prolonged period.

Many patients with a creatinine level around this range eventually require dialysis, but the timing is individualized. If your grandmother is stable, dialysis might be planned rather than needed as an emergency.

However, if any of the complications mentioned arise, dialysis may need to be initiated urgently. My advice is not to delay scheduling a consultation with a nephrologist. They will conduct a complete evaluation, including blood tests, urine analysis, an ultrasound, and a clinical assessment.

Based on their findings, they will decide whether to:

  1. Start dialysis soon.
  2. Prepare access for dialysis, such as a fistula.
  3. Manage her condition conservatively if she remains stable.

Please arrange a consultation with her reports so I can review her complete reports and symptoms and guide you on whether immediate dialysis is necessary or if we can optimize her treatment first.

I hope this answers your query. Feel free to reach out anytime.

Thank you.
