Nutrição e Litíase Renal – Artigo 15

Influência do estado nutricional e dos parâmetros laboratoriais e dietéticos sobre a excreção urinária ácida em pacientes portadores de litíase cálcica Resumo Introdução: A obesidade e a Síndrome Metabólica (SM) se associam a pH urinário ácido e representam fatores de risco para litíase renal, especialmente a úrica. Dietas acidogênicas também podem contribuir para a redução do pH urinário. Já foi demonstrado maior risco de precipitação de oxalato de cálcio em proporção aos critérios de SM. Objetivo: Avaliar retrospectivamente o impacto de parâmetros antrop...

Dietary Intake of Fiber, Fruit, and Vegetables Decrease the Risk of Incident Kidney Stones in Women: A Women's Health Initiative (WHI) Report Abstract Purpose—We evaluated the relationship between dietary fiber, fruit, and vegetable intake, and the risk of kidney stone formation. Methods—Overall, 83,922 postmenopausal women from the WHI Observational Study were included and followed prospectively. Cox proportional hazards regression analyses evaluated the associations between total dietary fiber, fruits, and vegetable intake, and the risk of incident kidney stone formation adjusting ...

Changes in urinary risk profile after shortterm low sodium and low calcium diet in recurrent Swiss kidney stone formers Abstract Background: Kidney stone disease is common in industrialized countries. Recently, it has attracted growing attention, because of its significant association with adverse renal outcomes, including end stage renal disease. Calcium-containing kidney stones are frequent with high recurrence rates. While hypercalciuria is a well-known risk factor, restricted intake of animal protein and sodium, combined with normal dietary calcium, has been shown to be more effective ...

Simple dietary advice targeting five urinary parameters reduces urinary supersaturation in idiopathic calcium oxalate stone formers Abstract Among 208 kidney stone patients referred within 2 years, 75 patients (66 men, nine women) with truly idiopathic calcium oxalate stones (ICSF) were recruited. Dietary advice (DA) aimed at (1) urine dilution, (2) reduced crystallization promotion (lowering oxalate), and (3) increased crystallization inhibition (increasing citrate). We recommended higher intakes of fluid and calcium with meals/snacks (reducing intestinal oxalate absorption) as well as ...

Kidney Stone Disease: An Update on Current Concepts Kidney stone disease is a crystal concretion formed usually within the kidneys. It is an increasing urological disorder of human health, a3ecting about 12% of the world population. It has been associated with an increased risk of end-stage renal failure. ,e etiology of kidney stone is multifactorial. ,e most common type of kidney stone is calcium oxalate formed at Randall’s plaque on the renal papillary surfaces. ,e mechanism of stone formation is a complex process which results from several physicochemical events including supersatur...

Dietary and lifestyle factors for primary prevention of nephrolithiasis: a systematic review and meta-analysis Abstract Background: Dietary and lifestyle factors may play an important role in the increasing prevalence of nephrolithiasis. We aimed to review and quantify the associations between lifestyle factors and incident nephrolithiasis and suggest lifestyle changes for the primary prevention of nephrolithiasis. Methods: PubMed, EMBASE, and Cochrane Library were searched up to May 2019, for observational studies and randomized controlled trials (RCTs) that assessed modifiable ...

Impact of Nutritional Factors on Incident Kidney Stone Formation: A Report From the WHI OS Abstract Purpose—Increased fluid intake, and decreased dietary sodium and animal protein intake are thought to reduce the risk of kidney stones but the role of calcium intake is controversial. We evaluated the relationship between dietary factors and incident kidney stone formation. Materials and Methods—Secondary analysis was done of 78,293 women from the prospective WHI OS (Women’s Health Initiative Observational Study) with no history of nephrolithiasis who completed the validated food ...

Nutritional aspect of nephrolithiasis ABSTRACT Nephrolithiasis is associated with a variety of abnormalities in urinary composition. These abnormal urinary risk factors are due to dietary indiscretions, physiological–metabolic disturbances or both. Stone disease is morbid and costly, and the recurrence rates may be as high as 30–50% after 5 years. Efforts to prevent stone formation are, therefore, essential. Dietary factors play an important role in kidney stone formation. Tailored dietary recommendations based on metabolic evaluation should be offered to patients for the prevention ...
