There are many reasons why patients with advanced hepatocellular carcinoma have less urine, so the specific treatment measures to relieve the treatment of less urine should also be based on the different causes of the disease to choose different options.
If the sodium and water retention is due to liver and kidney failure, this condition should be treated by minimizing the intake of water, including drinking an appropriate amount of water and eating less salt in daily life to reduce sodium and water retention, which causes generalized swelling. The patient with significant urinary deficit can consider the application of diuretics, clinically commonly used as furosemide tablets or hydrochlorothiazide, while the application of these drugs should pay attention to the supplementation of potassium ions to prevent the development of hypokalemia.
For advanced hepatocellular carcinoma with renal failure, dialysis can be used to treat urinary deficiency if necessary, which can rapidly eliminate metabolites and toxic products and improve survival and quality of life in this advanced stage.
For hyponatremia due to low-protein ascites, plasma albumin and fresh plasma can be infused to raise the plasma osmolality in the body, both of which are beneficial in reducing hyponatremia. Therefore, it is important to find the cause of this patient’s late onset of oliguria and treat it symptomatically to relieve the symptoms.
