Abstract:Dietary modifications should be considered as a first line approach in the treatment of idiopathic calcium oxalate nephrolithiasis. The amounts of oxalate and calcium consumed in the diet are significant factors in the development of the disease due to their impact on urinary oxalate excretion. There are a number of strategies that can be employed to reduce oxalate excretion. The consumption of oxalate-rich foods should be avoided and calcium intake adjusted to 1000–1200 mg/day. To encourage compliance it shou… Show more
“…Normally, intestinal oxalate absorption is low and highly variable (around 10%-15%) [56]. In individuals without malabsorption syndrome, bowel oxalate uptake may increase only when intestinal ionized Ca is reduced, often due to high dietary consumption of phytate (calcium-binding molecule) and/or low-calcium diet [57].…”
Nephrolithiasis is a common medical condition influenced by multiple environmental factors, including diet. Since nutritional habits play a relevant role in the genesis and recurrence of kidney stones disease, dietary manipulation has become a fundamental tool for the medical management of nephrolithiasis. Dietary advice aims to reduce the majority of lithogenic risk factors, reducing the supersaturation of urine, mainly for calcium oxalate, calcium phosphate, and uric acid. For this purpose, current guidelines recommend increasing fluid intake, maintaining a balanced calcium intake, reducing dietary intake of sodium and animal proteins, and increasing intake of fruits and fibers. In this review, we analyzed the effects of each dietary factor on nephrolithiasis incidence and recurrence rate. Available scientific evidence agrees on the harmful effects of high meat/animal protein intake and low calcium diets, whereas high content of fruits and vegetables associated with a balanced intake of low-fat dairy products carries the lowest risk for incident kidney stones. Furthermore, a balanced vegetarian diet with dairy products seems to be the most protective diet for kidney stone patients. Since no study prospectively examined the effects of vegan diets on nephrolithiasis risk factors, more scientific work should be made to define the best diet for different kidney stone phenotypes.

“…Containing high amount of calcium, dairy products reduce stone formation risk by decreasing intestinal absorption of oxalate [29]. However, there are several studies which suggest that there is not a correlation between dietary calcium intake and stone formation [30,31].…”

ConclusionResults of the study showed that total fluid intake, salt consumption habits, and vegetable, fruit and beverage consumption may be correlated with stone formation risk and nutrition habits may affect stone recurrence.
ObjetivoDeterminar o efeito de hábitos nutricionais na formação e recorrência de cálculos renais.
MétodosEste estudo foi realizado em 44 indivíduos saudáveis e 44 pacientes com diagnóstico de nefrolitíase e envelhecimento entre 20 e 65 anos. Os participantes compartilharam seus hábitos de consumo de sal, quantidades diárias de consumo de líquidos e informações gerais sobre si mesmos em um questionário. Além disso, as frequências de consumo de alimentos e bebidas dos participantes foram registradas por meio de um questionário de frequência alimentar.
ResultadosAs frequências de consumo de sal dos pacientes são maiores que as de indivíduos saudáveis em ambos os sexos (p<0,05). Verificou-se que os indivíduos do sexo masculino no grupo de pacientes salgam os pratos sem degustar com maior frequência (p<0,05). O consumo diário total de água de ambos os sexos no grupo de pacientes é menor que o dos indivíduos saudáveis (p<0,05). O consumo de carne de pacientes do sexo masculino (51,6±31,35g/dia) foi maior que o do grupo saudável (34,1±22,58g/dia) (p<0,05). Além disso, indivíduos do grupo de pacientes consomem menos urtiga, milho, ameixa, nêspera, suco de laranja e limonada do que indivíduos saudáveis (p<0,05).
ConclusãoOs resultados do estudo mostraram que a ingestão total de líquidos, os hábitos de consumo de sal e o consumo de vegetais, frutas e bebidas podem estar correlacionados com o risco de formação de pedra e os hábitos de nutrição podem afetar a recorrência da pedra.

“…A low oxalate diet, potassium citrate supplementation, and calcium supplementation are beneficial. Calcium therapy for hyperoxaluria deceases oxalate absorption linearly with increasing dietary calcium dose of up to 1200 mg/d …”
Short bowel syndrome (SBS) can lead to many complications related to the condition and its therapy. We describe 2 children with SBS who we believe are the second and third patients documented to have experienced both D-lactic acidosis and urolithiasis. We review aspects of these SBS complications and recent findings on the microbiome of patients with SBS that may predispose to these complications.
