Abstract Background The dietary habits and lifestyle changes during the COVID-19 pandemic could affect the urinary risk factors in kidney stone formers. In this study, we investigated the effects of the COVID-19 pandemic on 24-h urine metabolites, as a surrogate for dietary intake, in patients with kidney stones, in Tehran, Iran. Methods We evaluated the medical records of all patients with urolithiasis who visited in our stone prevention clinic from the beginning of COVID-19 in Iran to 1 year later (Feb 2020–Feb 2021) and compared it with the patients’ medical records in the same period a year before COVID-19 (Feb 2019–Feb 2020). Results The results of our stone prevention clinic showed a decrease in the number of visits during COVID-19. Twenty-four-hour urine urea, sodium, and potassium were significantly lower, and 24-h urine magnesium was significantly higher during COVID-19. Higher 24-h urine oxalate was only shown in patients with the first-time visit, whereas lower 24-h urine uric acid and citrate were only shown in patients with the follow-up visits. Conclusions COVID-19 pandemics may change some of the dietary habits of the patients, including lower salt, protein, and fruit and vegetable intake. Although economic issues, restricted access, or sanitation issues may be the reason for the undesirable dietary changes, the importance of a quality diet should be discussed with all patients, as possible. Since the number of patients visited in the stone clinic was lower during COVID-19, virtual visits could be an excellent alternative to motivate patients with kidney stones.

Reasons for not following the instructions about kidney stones prevention measures were the cost (53.1%) following by the lack of explanation by ED physicians (18.8%). The majority of patients (62.6%) prefer to receive kidney stones prevention measures from urologists.ConclusionMost of patients in our institute did not receive kidney stones prevention measures in ED despite that they declared their interest in following these measures. Most of the time they did not adhere to those measures due to socioeconomic factors and lack of clarifications. If these instructions were given within the ED, it could lead to an acceptable compliance rate.

Abstract Background Chronic kidney disease (CKD) and kidney stones are common in Taiwan; in particular, CKD has a high prevalence but low self-awareness rate. CKD-related risk factors such as diabetes, hypertension, and nephrotoxic drugs are well-known and uncontested; however, kidney stones are relatively less studied and easily overlooked as a risk factor. The objective of this study was to investigate whether kidney stones are a risk factor for CKD.Methods We conducted a nationwide population-based matched cohort study to assess the risk of incident CKD in people with kidney stones. Data on incident stones formers in the year 2001—excluding those with a history of CKD—were obtained from Taiwan’s National Health Insurance database. Stone formers were matched (1:4) to control subjects according to sex, age, and index date. The total observation period of the study was 10 years, and the primary end-point was the occurrence of CKD. Student’s t-test and Chi-squared test were used to compare continuous and categorical data, respectively. Logistic regression was used to calculate the odds ratio of kidney stone patients with incident CKD relative to the control group. Cox proportional hazard regression model was used to obtain the hazards ratio for development of incident CKD among patients with kidney stones.Results The incidence of CKD in the kidney stone cohort was 11.2%, which was significantly higher than that of the control group (P < .001). Survival analysis showed that the stones cohort was 1.82 times more likely to experience CKD than the controls. Age, sex, hypertension, diabetes mellitus, and hyperlipidemia increased the risk of CKD incidence (1.04, 1.27, 1.55, 3.31, and 1.25 times, respectively).Conclusion Kidney stones are a definite risk factor for CKD; therefore, patients with stones are suggested to undergo regular renal function monitoring and receive appropriate treatment to avoid CKD.

Objective: To evaluate the stone free rates of kidney and ureter stone patients managed by Extracorporeal Shockwave Lithotripsy (ESWL), and the ureter stone free rate managed by ureterolithotripsy. Material & method: We reviewed the medical records of kidney and ureter stone patients managed by ESWL and ureter stone patients managed by ureterolithotripsy in Arifin Achmad Regional General Hospital Pekanbaru Riau Province, Indonesia, from January 2010 - December 2016. ESWL and ureterolithotripsy stone free rates were examined by the control of KUB röngents. Results: There were 891 kidney and ureter stone patients consisting of 325 (36.5%) were kidney stone patients and 566 (63.5%) were ureter stone patients. The pyelum stones were the most (78.2%) in kidney stones and the lower ureter stones were the most (57.2%) in ureter stones. There were more male patients than the female ones in which most of the patients were in the group age of 49-59 years. The amount of patients increased each year. The kidney stone free rate managed by ESWL was lower (71.7%) than ureter stone free rate (84.1%) by ESWL, while the stone free rate of ureter stone patients managed by ureterolithotripsy was 100%. Conclusion: The ESWL stone free rate of the kidney stone patients was lower than the one in ureter stone patients while the ureterolithotripsy stone free rate was 100%.

Abstract Background and Aims Nephrolithiasis is a medical condition characterized by high prevalence among the general population both in Europe and in the U.S. and it is responsible for high costs reaching up to $10 billion per year. It is associated with specific comorbidities such as obesity, arterial hypertension, diabetes mellitus, metabolic syndrome and chronic kidney disease. Kidney stones development is believed to start either from Randall’s plaques or from stone plugs. Both these lesions can be seen on renal papillary surfaces, but what promotes the formation of plaques and plugs is not entirely understood. The aim of this study is to investigate the association between the urinary metabolic milieu and a published endoscopic papillary evaluation score (PPLA). We also evaluated the correlation of PPLA score with kidney stone recurrence during follow-up. Method We prospectively enrolled 31 stone forming patients who undergone retrograde intrarenal surgery procedures. Visual inspection of the accessible renal papillae was performed in order to calculate the PPLA score based on the appearance of ductal plugging, surface pitting, loss of papillary contour and Randall’s plaque extension. Demographic information, blood samples, 24h urine collections and kidney stone events during follow-up were collected. Stone composition was analyzed using infrared-spectroscopy. Relative urinary supersaturations (RSS) for calcium oxalate (CaOx), calcium phosphate (CaPi) and uric acid (UA) were calculated using the Equil2 software. PPLA score &gt; 3 was defined as high. Results Median follow-up period was 11 (min/max 5, 34) months. PPLA score was inversely correlated with BMI (rho = −0.39, p = 0.035) and history of recurrent kidney stones (median PPLA 5.0 vs 2.5, p = 0.029), these results were confirmed when PPLA was considered as a categorical variable (median BMI 27 vs 24, recurrent stone disease 12 vs 62%, p= 0.006). Furthermore, high PPLA score was associated with lower odds of new kidney stone events during follow-up (OR 0.154, 95% confidence interval 0.024, 0.998, p = 0.05). No significant correlations were found between PPLA score, stone composition, blood parameters, 24h urine solute excretions and RSS for CaOx, CaPi and UA. Conclusion Different papillary abnormalities seem to be linked to specific mechanisms of stone formation. Although data regarding PPLA score are inconsistent, it may be a valid asset for both medical and surgical management of nephrolithiasis. Larger, long-term prospective clinical studies need to be conducted to assess the validity of PPLA score system in evaluating risk of stone recurrence.

Diet is an important contributor to kidney stone formation, but there are limited data regarding long-term changes in dietary factors after a diagnosis of a kidney stone. We analyzed data from three longitudinal cohorts, the Health Professionals Follow-Up Study and the Nurses' Health Studies I and II, comparing changes in dietary factors in participants with and without a history of kidney stones during follow-up. The total daily intake of dietary calcium, supplemental calcium, animal protein, caffeine, fructose, potassium, sodium, oxalate, phytate, vitamin D, vitamin C, sugar-sweetened beverages, fluids, NEAP and DASH score were assessed by repeat FFQs and computed as absolute differences; a difference-in-differences (DID) approach was used to account for general temporal changes using data from participants without a history of kidney stones from the same calendar period. 184,398 participants with no history of kidney stones were included, 7,095 of whom became confirmed stone formers. Several intakes changed significantly over time in stone formers compared with non-formers, with some showing a relative increase up to 8 years later, including caffeine (DID 8.8 mg/day, 95% CI 3.4, 14.1), potassium (23.4 mg/day, 95% CI 4.6, 42.3), phytate (12.1 mg/day, 95% CI 2.5, 21.7), sodium (43.1 mg/day, 95% CI 19.8, 66.5) and fluid intake (47.1 mL/day, 95% CI 22.7, 71.5). Other dietary factors showed a significant decrease, such as oxalate (−7.3 mg/day, 95% CI −11.4, −3.2), vitamin C (−34.2 mg/day, 95% CI −48.8, −19.6), and vitamin D (−18.0 IU/day, 95% CI −27.9, −8.0). A significant reduction in sugar-sweetened beverages of −0.5 (95% CI −0.8, −0.3) and −1.4 (95% CI −1.8, −1.0) servings/week and supplemental calcium −105.1 (95% CI −135.4, −74.7) and −69.4 (95% CI −95.4, −43.4) mg/day for NHS I and NHS II, respectively intake was observed in women. Animal protein, dietary calcium, fructose intake, DASH score and NEAP did not change significantly over time. After the first episode of a kidney stone, mild and inconsistent changes were observed concerning dietary factors associated with kidney stone formation.

Previous studies have suggested that kidney stone formers are associated with a higher risk of cardiovascular events. To our knowledge, there have been no previous examinations of the relationship between carotid intima-media thickness (IMT) and urinary stone risk factors. This study was aimed toward an investigation of the association between dyslipidemia, IMT, and 24-hour urinalysis in patients with calcium oxalate (CaOx) or calcium phosphate (CaP) stones. We prospectively enrolled 114 patients with kidney stones and 33 controls between January 2016 and August 2016. All patients were divided into four groups, according to the stone compositions—CaOx ≥ 50% group, CaP group, struvite group, and uric acid stones group. Carotid IMT and the carotid score (CS) were evaluated using extracranial carotid artery doppler ultrasonography. The results of a multivariate analysis indicated that a higher serum total cholesterol (TC) and low-density lipoprotein (LDL) were all associated with lower urinary citrate and higher CS in both the CaOx ≥ 50% and CaP groups. Higher serum TC and LDL were also associated with increased serum 8-OHdG levels in both groups. The levels of carotid IMT and CS in the CaOx ≥ 50% and CaP groups were all significantly higher than in the controls. These findings suggest a strong link between dyslipidemia, carotid atherosclerosis, and calcium kidney stone disease.

BackgroundThe relationship between the composition and function of gut microbial communities and early-onset calcium oxalate kidney stone disease is unknown.MethodsWe conducted a case-control study of 88 individuals aged 4–18 years, which included 44 individuals with kidney stones containing ≥50% calcium oxalate and 44 controls matched for age, sex, and race. Shotgun metagenomic sequencing and untargeted metabolomics were performed on stool samples.ResultsParticipants who were kidney stone formers had a significantly less diverse gut microbiome compared with controls. Among bacterial taxa with a prevalence >0.1%, 31 taxa were less abundant among individuals with nephrolithiasis. These included seven taxa that produce butyrate and three taxa that degrade oxalate. The lower abundance of these bacteria was reflected in decreased abundance of the gene encoding butyryl-coA dehydrogenase (P=0.02). The relative abundance of these bacteria was correlated with the levels of 18 fecal metabolites, and levels of these metabolites differed in individuals with kidney stones compared with controls. The oxalate-degrading bacterial taxa identified as decreased in those who were kidney stone formers were components of a larger abundance correlation network that included Eggerthella lenta and several Lactobacillus species. The microbial (α) diversity was associated with age of stone onset, first decreasing and then increasing with age. For the individuals who were stone formers, we found the lowest α diversity among individuals who first formed stones at age 9–14 years, whereas controls displayed no age-related differences in diversity.ConclusionsLoss of gut bacteria, particularly loss of those that produce butyrate and degrade oxalate, associates with perturbations of the metabolome that may be upstream determinants of early-onset calcium oxalate kidney stone disease.
