Urolithiasis (UL) is increasingly prevalent due to rising cardiorenometabolic diseases, posing significant management challenges despite advances in urological techniques. Sodium-glucose cotransporter-2 (SGLT2) inhibitors, primarily used for type 2 diabetes mellitus, chronic kidney disease, and heart failure, have emerged as a potential novel approach for UL treatment. These inhibitors may help reduce the risk of urolithiasis, particularly in patients with diabetes, by improving glycemic control and altering urinary chemistry, which are crucial factors in stone formation. However, the changes in urinary composition induced by SGLT2 inhibitors might also increase the risk of uric acid stone formation. This review evaluates the potential of SGLT2 inhibitors in managing UL, highlighting both the benefits and the risks. While these inhibitors show promise in reducing new and recurrent urinary stones in patients with diabetes, data on their effects in patients without diabetes who form stones are limited. Current human evidence largely comes from post hoc analyses of randomized controlled trials (RCTs) and large-scale database studies, with only one study providing detailed stone composition data. Experimental studies in animal models and cell lines have focused on calcium oxalate (CaOx) stones, showing that SGLT2 inhibitors specifically target CaOx stone formation and related renal inflammation. Although primarily studied for CaOx stones, their potential impact on other calcium-containing stones, such as calcium phosphate, remains promising. Further research is needed to explore their therapeutic potential and optimize treatment strategies.

Background. National surveys have reported variable prevalence of chronic kidney disease (CKD), due to differences in the characteristics of the population, study design, equations used for the estimated glomerular filtration rate (eGFR), and definitions. The EH-UH 2 survey is the first study evaluating CKD prevalence, characteristics, and awareness in Croatia. Methods. This was a cross-sectional nationwide observational study designed to assess the prevalence of CKD and cardio–kidney–metabolic risk factors in Croatia, which included 1765 randomly selected subjects. We estimated the prevalence of CKD by means of the albumin-to-creatinine ratio (ACR) and eGFR (CKD-EPI equation). Comorbidities and anthropometric and social factors related to the prevalence of CKD were analyzed, and the CV risk profile was evaluated. Results. The weighted prevalence of CKD (any stage), CKD stage ≥G3A A2, and CKD defined only as an eGFR <60 mL/min/1.73 m² were estimated at 17.1%, 9.8%, and 7.9%, respectively. The prevalence was higher in men than in women (11.8% vs. 7.9%; p < 0.001). The weighted prevalence of an ACR >30 mg/g was 15.1%. Older age, male gender, diabetes, ePWV, and uric acid were independently associated with CKD prevalence. The awareness of CKD was 9.5%. Persons unaware of CKD were older with lower income, less education, more frequent diabetes, hypertension (less frequently controlled), and milder renal impairment. Conclusions. In Croatia, the estimated prevalence of CKD is high, being presented more frequently in men than in women. CKD patients have an unfavorable CV risk profile. The awareness of CKD is very low, reflecting poor health literacy in the general population but also in health-care workers.

Renal denervation (RDN) as a method of treating arterial hypertension (AH) was introduced in Croatia in 2012. A multidisciplinary team and a network of hospitals that diagnose and treat patients with severe forms of AH were established, and a very strict diagnostic-treatment algorithm was prepared. At monthly meetings patients with truly resistant hypertension who were candidates for RDN were discussed. According to the 2021 ESH position statement and 2023 ESH guidelines, RDN is considered an alternative and additional, not a competitive method of treating patients with various forms of AH which must be performed by following a structured procedure and the patient’s preference should be considered. In view of the changes in the global scientific community, the Croatian Hypertension League brings this consensus document on RDN conducted with radiofrequency-based catheter, the only currently available method in Croatia. In this document, exclusion and inclusion criteria are shown, as well as three groups of patients in whom RDN could be considered. The new diagnostic-treatment algorithm is prepared and follow-up procedure is explained. In Croatia, RDN is reimbursed by the national insurance company, thus pharmacoeconomic analyses is also shown. Criteria required by an individual centre to be approved of RDN are listed, and plans for prospective research on RDN in Croatia, including the Croatian registry for RDN, are discussed.

Although significant progress has been made in reducing salt consumption over the past decade, most Croatian adults still exceed the recommended intake. This study aimed to identify demographic, socioeconomic, lifestyle, and clinical factors associated with high salt intake in the general adult population of Croatia. We included a random sample of 1067 adults with reliable 24-h urine samples. A structured questionnaire was used to collect sociodemographic, lifestyle, and clinical data. Anthropometric and blood pressure (BP) measurements were performed. Laboratory analyses included the measurement of sodium, potassium, and creatinine in adequate 24-h urine samples, as well as relevant cardiometabolic and kidney-related biomarkers. Participants consuming > 10 g/day of salt were older and had higher systolic blood pressure, fasting glucose, serum uric acid, and triglyceride levels, lower HDL cholesterol levels, and greater BMI. High salt intake was more common among men, ex-smokers, participants with diabetes, and those with lower socioeconomic status (SES). In multinomial logistic regression analysis, male sex, diabetes, higher systolic BP, more frequent processed meat consumption, lower fish consumption, residence outside the Adriatic region, and higher ePWV were associated with high salt intake. High salt intake was associated with lower socioeconomic status, residence in rural and continental areas, obesity, former smoking, and less favorable dietary patterns. Conversely, lower salt intake was associated with residence in the Adriatic region and dietary patterns characterized by more frequent consumption of fish and olive oil.
