Hepatorenal Syndrome
Hepatorenal syndrome represents one of the most challenging intersections of liver and kidney disease. Our specialized nephrology team provides 24/7 dialysis support for cirrhosis patients with acute kidney failure, bridging to transplant or recovery.
Understanding Hepatorenal Syndrome
Hepatorenal syndrome (HRS) occurs when advanced liver disease triggers kidney failure through severe vasoconstriction of the renal arteries. The kidneys themselves are structurally normal—if transplanted into a healthy recipient, they would function perfectly.
HRS is classified into two types:
- Type 1 HRS: Rapidly progressive, with creatinine doubling to >2.5 mg/dL within 2 weeks. Often triggered by infection, bleeding, or paracentesis. Median survival without treatment is 2 weeks.
- Type 2 HRS: More gradual decline, typically associated with refractory ascites. Slower progression allows more time for transplant evaluation.
- Diagnosis of exclusion: Must rule out other causes of AKI (hypovolemia, nephrotoxins, obstruction, intrinsic renal disease)
- Reversibility: Kidneys can recover with liver transplant or, in some cases, medical therapy with vasoconstrictors and albumin
When to Call for Nephrology Support
Early coordination is critical. HRS patients often need dialysis as a bridge to liver transplant. Early nephrology involvement allows us to optimize timing and modality selection.
Our Approach to Hepatorenal Syndrome
Specialized protocols for the unique challenges of kidney failure in liver disease
Rapid Response
On-site nephrology consultation within hours. We understand the urgency of HRS Type 1 and prioritize these cases.
Gentle Dialysis Modalities
CRRT or SLED for hemodynamically unstable patients. Avoids rapid fluid shifts that cirrhotic patients tolerate poorly.
Electrolyte Management
Careful correction of hyponatremia and other electrolyte abnormalities common in advanced liver disease.
Hemodynamic Optimization
Coordination with hepatology for vasoconstrictor therapy. Dialysis timing aligned with medical management.
Transplant Coordination
Close communication with liver transplant teams. Dialysis serves as a bridge while awaiting organ availability.
Combined Transplant Support
Experience with simultaneous liver-kidney transplant candidates. Comprehensive pre- and post-transplant dialysis care.
For Hepatologists & Liver Transplant Teams
We recognize that HRS management requires close collaboration between nephrology and hepatology. Our team integrates with your liver program to provide seamless renal support throughout the transplant journey.
- 24/7 attending nephrology coverage for urgent HRS cases
- Experience with terlipressin, midodrine/octreotide protocols
- CRRT for patients too unstable for intermittent dialysis
- Support for combined liver-kidney transplant evaluation
- Collaboration with your MELD exception applications
- Post-transplant dialysis management if needed

Frequently Asked Questions
When should dialysis be started in hepatorenal syndrome?
Dialysis in HRS is typically initiated when medical therapy (vasoconstrictors + albumin) fails, or when urgent indications arise (hyperkalemia, severe acidosis, volume overload). The decision is made collaboratively with hepatology, considering transplant candidacy and prognosis.
Does dialysis improve survival in HRS?
Dialysis itself does not reverse HRS but can serve as a bridge to liver transplant. Without transplant, long-term prognosis remains poor. The goal is to maintain metabolic stability while awaiting definitive treatment. For transplant candidates, dialysis can be lifesaving.
What dialysis modality is best for HRS patients?
We typically favor CRRT or SLED (sustained low-efficiency dialysis) for HRS patients due to their hemodynamic instability. These modalities are gentler and avoid the rapid fluid and solute shifts that cirrhotic patients tolerate poorly.
Can kidneys recover after liver transplant?
Yes, in pure HRS (without underlying intrinsic kidney disease), kidneys often recover function after successful liver transplant. This is because HRS is a functional problem caused by liver failure, not structural kidney damage.
How do you coordinate with liver transplant teams?
We maintain direct communication with transplant hepatologists and surgeons. We provide documentation for MELD exception applications, participate in multidisciplinary meetings, and ensure dialysis scheduling doesn't conflict with transplant evaluation or surgery.
