“…Restriction of dietary calcium intake proved less effective than salt and protein restriction in preventing kidney stone recurrence [62]. However, the effect of dietary calcium on stone-forming propensity also depends on the oxalate content of the diet (i.e., the calcium/oxalate balance) and on the timing of calcium consumption [99,[119][120][121]. In fact, stone formers have a higher fractional intestinal calcium absorption than subjects not suffering from nephrolithiasis, and foods with high calcium content should be consumed during balanced meals to protect against the risk of hypercalciuria [122][123][124].…”

Calcium Oxalate Nephrolithiasis and Gut Microbiota: Not just a Gut-Kidney Axis. A Nutritional Perspective

Recent studies have shown that patients with kidney stone disease, and particularly calcium oxalate nephrolithiasis, exhibit dysbiosis in their fecal and urinary microbiota compared with controls. The alterations of microbiota go far beyond the simple presence and representation of Oxalobacter formigenes, a well-known symbiont exhibiting a marked capacity of degrading dietary oxalate and stimulating oxalate secretion by the gut mucosa. Thus, alterations of the intestinal microbiota may be involved in the pathophysiology of calcium kidney stones. However, the role of nutrition in this gut-kidney axis is still unknown, even if nutritional imbalances, such as poor hydration, high salt, and animal protein intake and reduced fruit and vegetable intake, are well-known risk factors for kidney stones. In this narrative review, we provide an overview of the gut-kidney axis in nephrolithiasis from a nutritional perspective, summarizing the evidence supporting the role of nutrition in the modulation of microbiota composition, and their relevance for the modulation of lithogenic risk.

“…Experiments in rats have suggested that increased dietary calcium intake can prevent calcium oxalate stone formation only when the diet is oxalate rich. 7 Of late, our group has noticed an increase in the prevalence of nephrolithiasis in our patients who have undergone RYGBP, with the calculi predominantly calcium oxalate. Considering the relative dearth of literature discussing the association between enteric hyperoxaluria= nephrolithiasis and Roux en Y procedures, we determined that sharing our observations and experience in the form of a case study was both a necessary contribution to the literature and an important means of understanding and raising awareness of the increased risks of these conditions.…”

Historically, the development of enteric hyperoxaluria has been well recognized as a potential risk following the bariatric procedures jejunoileal bypass ( JIB) and distal bypass. However, the occurrence of enteric hyperoxaluria has not been recognized as an associated, prevalent risk after Roux-en-Y gastric bypass (RYGBP). An increased rate of nephrolithiasis was observed in the Roux-en-Y patient population at the Columbia University Center for Metabolic & Weight Loss Surgery. A representative case of recurrent bilateral oxalate stone formation in a patient following RYGBP at the center is reported. Enteric hyperoxaluria and nephrolithiasis must be considered potential risks associated with any malabsorptive surgery, including RYGBP. Prevention of the development of hyperoxaluria is multifactorial and includes recognition of potential preoperative risk factors, postoperative follow-up evaluations, and attentive nutritional guidance. These patient management areas represent opportunities that need to be recognized and addressed in the prevention of hyperoxaluria in patients undergoing RYGBP.
