Methods for the dietary assessment of adult kidney stone formers: a scoping review

Abstract

Background Kidney stones are a frequent and potentially severe condition, affecting 5–10% of the European population. Causes are multifactorial, diet in particular plays a major role in the formation and management of kidney stones. The aim of this scoping review is to assess the methods used to study the diet of adult kidney stone formers. Methods We conducted a systematic search in Medline Ovid SP, Embase, Cinahl, Cochrane (CENTRAL), Web of Sciences databases on June 10th, 2020. Self-report methods (such as food frequency questionnaires or 24-h dietary recalls), objective nutritional biomarkers and controlled diets were considered. We analyzed the selected publications based on the origin of participants, study design and dietary assessment methods used. Results We screened 871 publications and included 162 of them. Most studies included participants from North America and Europe and were observational. Short and cost-effective tools such as food frequency questionnaires and other questionnaires were the most frequently used. Moreover, food diary was a frequently selected method to study the diet of kidney stone formers. New technologies (e.g. online questionnaires, phone applications, connected tools) were rarely used. Conclusion Accurate reporting of the methods used in nutritional studies is of key importance to interpret results and build evidence. Assessing long-term dietary intake is still a challenge for nutritional epidemiology. A combination of self-report methods with objective dietary biomarkers and new technologies probably represents the best way forward. Graphical abstract

Comparison of the Effects of Laparoscopic Surgery and Traditional Open Surgery on Stone Clearance, Laboratory Indexes and Life Quality in Patients with Renal Calculi

“…This study was also indicated that laparoscopic surgery was better than traditional surgery in these three aspects. The reason may be that long-term surgical posture has an adverse effect on the comfort of patients, which may affect the late recovery of patients [ 27 ]. In addition, laparoscopic surgery has fewer complications than traditional surgery, which is also one of the reasons for the high life quality of patients.…”

The Swiss Kidney Stone Cohort: A Longitudinal, Multicentric, Observational Cohort to Study Course and Causes of Kidney Stone Disease in Switzerland

“…The importance of diet for kidney stone disease has been known for a long time and been confirmed in various cohorts such as NHANES and others [19,[29][30][31][32]. However, in these cohorts, information on diet is mostly derived from FFQ or other forms of retrospective interviews [33]. Most food questionnaires assess dietary intake only for groups of nutrients (i.e., proteins, fat, carbohydrates) or the frequency or size of meals.…”

Dietary weight loss strategies for kidney stone patients

“…Self-reported methods based on recall, such as food frequency questionnaires or 24-h dietary recalls, or based on real-time recordings, e.g. food diaries, in combination with objective nutritional biomarkers, are useful options for assessing the dietary habits of kidney stone patients [ 28 ]. In addition to the type and quantity of food consumed, the timing of meals and the type and volume of beverages consumed should also be recorded.…”
