Introduction: The ‘‘spot’’ urine sodium/potassium (Na/Ku) ratio is a convenient tool to identify sodium excretion < 78 mequiv./d. It has been established that this ratio is as useful and accurate as 24-h urine sodium (Nau24h), but no Latin American study has evaluated this issue. The aim of this study is to evaluate the accuracy of the Na/Ku ratio and to compare it to Nau24h. Materials and methods: This cross-sectional study included 20 patients with decompensated liver cirrhosis and ascites… Expand

Diagnostic usefulness of the spot urine sodium/potassium ratio in cirrhotic patients with ascites
The spot urine Na/K ratio reflects 24-h uNa, but the AUROC value obtained in this study is lower than that of a previous study. Expand

Second-void urine is more reliable than first- void urine for estimating 24UNa, and based on the second-void spot urine of the first day tended to be more closely correlated with measured 24 UNa than were estimates from the other spot urine samples. Expand
Correlation Between MELD and UNa/K Ratio in Predicting Renal Dysfunction in Cirrhotic Patients
The inverse correlation between MELD scores and UNa/K ratio indicates that patients with CLD and higher MELD score might have renal dysfunction, which should be corroborated by large scale studies. Expand


The Diagnostic Value of Spot Urine Sodium-to-Potassium (UNa/K) Ratio Compared to 24-hour Urine Sodium (24-hr UNa) for the Management of Cirrhotic Patients with Ascites
The spot UNa/K ratio ≥1 has a good sensitivity but very low specificity to predict adequate 24-hr UNa excretion, even at the best cut off point at 3, it still had low sensitivity and specificity. Expand
Spot urinary sodium for assessing dietary sodium restriction in cirrhotic ascites.
Spot urine Na/K ratio has adequate accuracy for assessment of dietary sodium restriction compared with 24-h urinary sodium in patients with liver cirrhosis and ascites. Expand
[Diagnostic usefulness of the random urine Na/K ratio in cirrhotic patients with ascites: a pilot study].
The results suggest that anytime random UNa/K greater than 1.25 is an accurate, cost-effective, and convenient method for replacing 24-h UNa. Expand
Can 24‐h urine sodium excretion be replaced by spot urine sodium/potassium in patients with decompensated cirrhosis?
Longterm monitoring shows hepatitis B virus resistance to entecavir in nucleoside-naive patients is rare through 5 years of therapy, as well as improved virologic, biochemical, and serology outcomes through 96 weeks of therapy. Expand
Urinary neutrophil gelatinase-associated lipocalin as biomarker in the differential diagnosis of impairment of kidney function in cirrhosis.
UNGAL levels may be useful in the differential diagnosis of impairment of kidney function in cirrhosis and urinary tract infections should be ruled out because they may increase uNGAL excretion. Expand
Ascites and hepatorenal syndrome in cirrhosis: pathophysiological basis of therapy and current management.
The current article is focused on the treatment of ascites and HRS in cirrhosis and the rationale of the therapeutic measures used in patients with cirrhotic patients with ascites or HRS is briefly reviewed. Expand

The survival of cirrhotic patients with first episode of ascite is relatively high, and it is mainly influenced by age and Child-Pugh score at the time of ascites decompensation, as well as by DH development. Expand
Refractory ascites: pathogenesis, definition and therapy of a severe complication in patients with cirrhosis
One of the most serious complications in cirrhotic patients with ascites is the occurrence of refractoriness, that is the inability to resolve ascites by the standard medical treatment with low sodium diet and diuretic doses. Expand
Compensated cirrhosis: Natural history and prognostic factors
To investigate the natural history of compensated cirrhosis, 293 consecutive patients without previous major complications were studied in terms of morbidity and survival and a prognostic index was constructed that allows calculation of the estimated survival probability. Expand
A model to predict survival in patients with end‐stage liver disease
The MELD scale is a reliable measure of mortality risk in patients with end‐stage liver disease and suitable for use as a disease severity index to determine organ allocation priorities in patient groups with a broader range of disease severity and etiology. Expand
