dc.description.abstractLa esteatosis hepática o hígado graso (HG) es un depósito principalmente de triacilgliceridos, dentro del hepatocito y que usualmente excede al 5% del volumen hepático, tradicionalmente se ha considerado como una condición benigna y reversible, siendo una expresión del hígado ante un estrés metabólico de diferentes orígenes.(1) puede presentar una evolución hacia la esteatohepatitis, con el eventual desarrollo de cirrosis no alcohólica no colestásica y el riesgo de carcinoma hepatocelular.(2) Esta patología afecta alrededor del 1-51% de la población adulta, variabilidad explicada por los diversos tipos de estudios poblacionales así como por las diferentes causas que conllevan a este diagnóstico. (2) La urolitiasis es una patología prevalente con alta recurrencia, que no solo genera dolor sino también un alto costo económico importante que va desde la limitación laboral al costo terapéutico, teniendo en cuenta que los procedimiento quirúrgicos no evitan la recurrencia de la patología, en comparación con los cambios que genera modificar el estilo de vida. (3) Actualmente ha aumento la incidencia y prevalencia de urolitiasis a nivel mundial, con variaciones que oscilan entre 16.9% al 18.5% dependiendo de la población de interés, se han reportado incidencias de 1116 por 100.000 habitantes en edades promedio entre los 40-49 años y con mayor frecuencia en hombres. (4,5) ASCOFAME para 1998 publico egresos por litiasis renal que corresponde a 13 por 1000 consultas, con una mayor frecuencia en climas cálidos. (6) Por consiguiente aproximadamente el 5% de las mujeres y el 12% de los hombres desarrollaran un episodio de litiasis en algún momento de su vida, lo cual generara un gasto anual cercano a 2.1 billones de dólares. (7) Estudios observacionales han sugerido la asociación entre hígado graso y la formación de litiasis renal, especialmente en dietas con alto contenido de colesterol que ocasionan, aumento en las concentraciones de oxalato de calcio en orina con la consiguiente formación de cálculos renales.spa

dc.description.abstractenglishHepatic steatosis or fatty liver (HG) is a deposit mainly of triacylglycerides, within the hepatocyte and that usually exceeds 5% of the liver volume, traditionally it has been considered as a benign and reversible condition, being an expression of the liver in the face of metabolic stress of different origins. (1) it may present an evolution towards steatohepatitis, with the eventual development of non-alcoholic non-cholestatic cirrhosis and the risk of hepatocellular carcinoma. (2) This pathology affects around 1-51% of the adult population, variability explained by the various types of population studies as well as by the different causes that lead to this diagnosis. (two) Urolithiasis is a prevalent pathology with high recurrence, which not only generates pain but also an important high economic cost that ranges from labor limitation to therapeutic cost, taking into account that surgical procedures do not prevent the recurrence of the pathology, compared to the changes generated by modifying the lifestyle. (3) Currently, the incidence and prevalence of urolithiasis has increased worldwide, with variations that range between 16.9% to 18.5% depending on the population of interest, incidences of 1116 per 100,000 inhabitants have been reported in average ages between 40-49 years and more often in men. (4,5) ASCOFAME for 1998 published discharges for kidney stones that correspond to 13 per 1000 consultations, with a higher frequency in hot climates. (6) Consequently, approximately 5% of women and 12% of men will develop an episode of lithiasis at some point in their life, which will generate an annual expense of close to 2.1 billion dollars. (7) Observational studies have suggested the association between fatty liver and the formation of kidney stones, especially in diets with a high cholesterol content that cause an increase in calcium oxalate concentrations in urine with the consequent formation of kidney stones.eng
