Differential Diagnosis for Distended Abdomen in CKD Patients on IFC with No Urine Output

Single Most Likely Diagnosis

  • Fluid Overload: In patients with chronic kidney disease (CKD) on intermittent fluid cycling (IFC, also known as intermittent hemodialysis) with no urine output, fluid overload is the most common cause of a distended abdomen. This condition occurs due to the inability of the kidneys to remove excess fluid from the body, leading to accumulation in various compartments, including the abdominal cavity.

Other Likely Diagnoses

  • Constipation: Constipation is a common issue in CKD patients, which can be exacerbated by fluid restrictions and medications. It can cause abdominal distension due to the accumulation of feces in the bowel.
  • Ascites: Ascites, the accumulation of fluid in the peritoneal cavity, can occur in CKD patients, especially those with more advanced disease or those undergoing dialysis. It can be due to fluid overload or other complications like liver disease.
  • Peritoneal Dialysis-Related Complications: For patients on peritoneal dialysis, complications such as peritonitis or dialysate leakage into the abdominal cavity can cause distension.

Do Not Miss Diagnoses

  • Intra-Abdominal Infection or Abscess: Although less common, an intra-abdominal infection or abscess can be life-threatening and must be considered, especially if there are signs of infection or sepsis.
  • Bowel Obstruction: A bowel obstruction can cause severe abdominal distension and is a medical emergency. It may be due to various causes, including adhesions from previous surgeries, hernias, or tumors.
  • Retroperitoneal Hemorrhage: Bleeding into the retroperitoneal space can occur in CKD patients, especially those on anticoagulation for dialysis, and can cause abdominal distension.

Rare Diagnoses

  • Abdominal Tumor: Although rare, abdominal tumors can cause distension, either by the mass effect of the tumor itself or by causing bowel obstruction.
  • Malnutrition-Related Ascites: In severe cases of malnutrition, which can occur in advanced CKD, ascites may develop due to hypoalbuminemia.
  • Chylous Ascites: This is a rare condition where lymphatic fluid accumulates in the abdominal cavity, which can occur in patients with severe kidney disease affecting lymphatic drainage.
