Recurrent Stone Formers

Urinary stones are predominantly composed of calcium oxalate and calcium apatite while a minority of stones are formed from uric acid. The oxalate stones occur with greatest frequency, mainly in the form of the monohydrate (whellewite) with some dihydrate (wedellite) present. Despite many years of extensive research, the mechanisms for kidney stone nucleation and growth are still unknown. In particular the urine from recurrent stone formers, and the urine from those who do not form stones, does not show large differences in concentration of either calcium or oxalate ions. Recent work has emphasised the role of possible “inhibitors” or “promoters” in the growth of urinary stones though the quest for these substances remains elusive. Much effort has been devoted to the study of crystallization of calcium oxalates in an attempt to understand nucleation, aggregation and growth as a function of pH and the presence of possible promoters or inhibitors.Many analytical techniques have been applied to urinary stone analysis with X-ray diffraction, wet chemistry and infrared spectroscopy being the most successful for routine characterisation.

We explored national trends in the receipt of high-quality patient–physician communication and patient empowerment through behavioral health counseling among children in the United States. We used data from the Medical Expenditure Panel Survey from 2010 to 2014. We employed two measures of patient- and family-centered care (PFCC): (1) a composite measure of high-quality patient–physician communication ( n = 34,629) and (2) patient empowerment through behavioral health counseling about healthy eating ( n = 36,527) and exercise ( n = 38,318). We used multivariate logistic regression models to estimate the variation of receiving PFCC by social determinants of health over time. Rates of receiving behavioral health counseling about healthy eating (53–60%) and exercise (37–42%) were lower than the rate of receiving high-quality physician–patient communication (92–93%). Parents were significantly more likely to report receiving high-quality physician–patient communication in 2014 than in 2010 (odds ratio 1.37, confidence interval 1.08–1.67); however, no association was found for empowerment through behavioral health counseling. Low income and parental educational attainment, and lack of insurance were associated with lower odds of receiving behavioral health counseling. Results showed significant variation of physician–patient communication and empowerment by social and demographic factors. The results suggest more providers need to empower parents and their children to self-care through behavioral health counseling.

Abstract We used a xylitol load to test the two-carbon pathway to oxalate production in humans. Use of this pentose sugar caused a fourfold increase in glycolate excretion, indicating its suitability as a dynamic function test of two-carbon metabolism. However, despite this increase in glycolate excretion in 10 recurrent stone formers and six normal subjects, there was no concomitant increase in oxalate excretion in either group. By comparison, a sucrose load produced no increase in excretion of either glycolate or oxalate. In addition, when we studied four recurrent calcium stone formers on successive diets with various fat content, we found no correlation between high fat intake and increased glycolate or oxalate excretion. In summary, there was no evidence of abnormal fluxes through the two-carbon pathway to oxalate in recurrent stone formers, nor of hyperoxaluria as related to increased intake of sucrose or fat.

Recurrent Stone Formers

Abstract Studies of recurrent stone formers indicated that they have significantly increased urinary oxalate and decreased ascorbate excretions. Results of oral and intravenous administration of ascorbate indicate an enhanced production of oxalate from ascorbate in recurrent calcium stone formers as compared with normal persons and that most of this oxalate is generated in the gut.
