What causes kidney stones: Mayo Clinic Radio Health Minute
If you've ever had one, you know that passing a kidney stone can be a very uncomfortable experience. In this Mayo Clinic Radio Health Minute, we talk with Dr. David Patterson about why kidney stones form. To listen, click the link below. What causes kidney stones

Intestinal regulation of oxalate absorption is a complex mechanism, not exclusively reliant on the oxalate-degrading anaerobe Oxalobacter formigenes. Using metagenomics, Miller et al. were able to describe a network of bacterial taxa co-occurring with Oxalobacter formigenes in fecal samples from non–stone forming controls and less represented in stone formers. These findings may help to illuminate why previous intervention studies with probiotics have failed to reduce the risk of hyperoxaluria, opening new possibilities for future research.
Although vitamin C is essentially a nontoxic vitamin; however, it is important to be aware regarding the safety of high doses before the wide clinical use. Minor side effects of vitamin C have been reported, many being reported in earlier studies. High doses of vitamin C (up to 1.5 g/kg three times a week as intravenously) were safe in cancer patients with normal renal function and perfect glucose-6-phosphate dehydrogenase activity. As the dose and duration of administration of vitamin C in sepsis are lower and shorter than those used in cancer patients, it seems that it is relatively safe for this population. In ongoing t...
Conclusions: In our study, the overall adherence to the clinical guidelines regarding the therapeutic indication for urinary lithiasis has been low. In the case of both renal and ureteral stones, the adherence in small lithiasis has been greater, compared with larger ones. In our survey, a trend has been observed in favor of endoscopic procedures even in large lithiasis.Urol Int

(Harvey L. Neiman Health Policy Institute) A new study performed in conjunction with the Harvey L. Neiman Health Policy Institute examines changing characteristics of utilization and potential disparities in US emergency department (ED) patients undergoing CT of the abdomen and pelvis (CTAP) for suspected urolithiasis.

AbstractUrolithiasis is a common urologic problem among adults worldwide. It is interesting that urinary stones tend to recur on the same side and the pathophysiology of unilateral stone formation is not clearly understood. Researchers found that sleep posture could alter renal perfusion, and subsequent vascular injury may lead to urolithiasis formation. The aim of this study is to retrospectively evaluate the correlations between the specific sleep postures recorded in polysomnography (PSG) and the stone laterality in unilateral urinary stone formers with obstructive sleep apnea (OSA). We retrospectively reviewed patients...
