Outcome of Kidney Alone Transplantation in Patients with End Stage Kidney Disease with Compensated Cirrhosis

Ascites in patients with end-stage renal disease: Challenges and solutions from diagnosis to management

Metabolic diseases have exponentially increased in recent years, which has led to an increased prevalence of metabolic dysfunction-associated steatotic liver disease and concomitant kidney diseases. Ascites are a common presentation of cirrhosis, and renal impairment in cirrhosis is well described. However, patients with end-stage renal disease (ESRD) may also present with ascites even in the absence of cirrhosis. The literature on the management of patients with ESRD with ascites with or without concomitant cirrhosis is limited. Massive ascites in this population are often refractory to medical therapy and are associated with dismal prognosis. Pathophysiologically, increased hepatic vein hydrostatic pressure, fluid retention, increased peritoneal membrane permeability, and impaired peritoneal lymphatic drainage are proposed mechanisms for ascites in ESRD without cirrhosis. Identifying underlying cirrhosis and portal hypertension (PH) has therapeutic implications in such patients. However, diagnostic tools such as serum ascites albumin gradient and noninvasive tests to identify cirrhosis have limited utility in ESRD. Hemodialysis and continuous ambulatory peritoneal dialysis are effective but can be associated with hemodynamic compromise and peritonitis, especially in those with PH. TIPS for ascites has a limited role in the presence of ESRD due to the increased risk of HE. Kidney transplant is the treatment of choice in ESRD with ascites without PH. Simultaneous liver-kidney transplant remains the definitive treatment in the presence of PH, but is less commonly feasible, and kidney transplant alone in the presence of PH can be associated with the risk of decompensations. This review discusses the approach and management of ascites in chronic kidney disease and ESRD specifically.
