“…Patients who experienced the highest number of stones were between 41 and 60 years of age. These results are similar to those described in some studies from other countries [10][11][12][13][14].…”

“…As observed in many studies, mean age of patients experiencing stones of cystine, COD, carbapatite, brushite and ammonium hydrogen urate were under 50. Conversely, the oldest patients had more uric acids as major component of their stones, which is consistent with previous observations showing a rising number of UA calculi with age [14,16,17,19]. Finally, COM was the major component in each age group except for children younger than ten years, for whom carbapatite was the predominant component and accounted for 30% of all stones for each gender.…”

“…This ranking was found similar in other countries [13,15,17,19]. A gradual increase in frequency of uric acid stones has been observed for the recent years in different countries [6,11,14,18]. This progression seems to be due to the increase of obesity and type 2 diabetes mellitus associated with a higher susceptibility of women to develop nephrolithiasis in those cases.…”

“…Within the most frequent compounds, we did not observe any evolution over the ten years except an increase for COD frequency (23.1% to 47.4%). A gradual frequency rise of uric acid stones [6,11,14,18] was not found in our series. For these latter components, our results did not show any clear growing trend along the ten years studied as reported in a German study from 1977 to 2006 [16].…”

Several studies have reported a worldwide increase in incidence and prevalence of nephrolithiasis, with some specificities across countries and regions. A retrospective review was performed on all urinary calculi submitted between 2009 and 2019 from a large part of the western Switzerland to our laboratory. A total of 10,437 stones were analysed and the presence of 18,804 compounds revealed. The median age of patients was 51 years and the global male-to-female ratio was 2.49:1. From 2009 to 2019, calcium oxalates containing calculi were the most frequent, followed by calcium phosphate and uric acids, the latter being more common in men, whereas carbapatite was the second most frequent component in women. Infection stone frequency remained unchanged and low, with a higher rate for women. Finally, while Randall's plaque frequency was relatively small (7.4%), patients experiencing them were significantly younger. In this review, we identified an age and gender relationship of stone composition and Randall's plaque formation in our Swiss region, which paves the way for future investigations.

“…Globally, the prevalence and recurrence rates of kidney stone disease are increasing [ 1 , 2 ]. It affects all ages, both sexes and all races; however, it occurs more commonly among males than females aged 40–60 [ 3 , 4 ]. Approximately 10–12% of the population will be affected by kidney stones at some stage of their lives .…”

Chronic hepatitis B virus infection increases the risk of upper urinary calculi

Background Although hepatitis B virus (HBV) is a recognized risk factor for renal diseases, little is known about HBV infection in individuals with upper urinary calculi (UUC). We investigated the relationship between chronic HBV infection and UUC. Methods We retrospectively analysed data from 1399 patients who were discharged from the Department of Urology (2017–2018). The diagnosis of UUC was determined using urinary tract ultrasonography or computed tomography, and HBV infection was evaluated by a positive hepatitis B surface antigen (HBsAg) test. Data on patients with and without UUC and HBsAg-positive and HBsAg-negative patients were compared by univariate and multivariate analyses. Results Data on chronic HBV infection and UUC were available for 1062 patients, including 514 who presented with UUC and 548 who did not. Overall, 5.8% of total patients, 8.0% of UUC patients and 3.8% of non-UUC patients had chronic HBV infection. UUC patients (41/514) had a significantly higher prevalence of HBsAg positivity (OR 2.175; 95% CI 1.267–3.734; P = 0.004) than non-UUC patients (21/548). After stratifying by sex, the relative odds of HBsAg positivity were statistically significant in men (OR 2.156; 95% CI 1.162–4.003; P = 0.015) but not in women (OR 2.947; 95% CI 0.816–10.643; P = 0.099). The incidence of urinary pH > 6 and staghorn stones was significantly higher in HBsAg-positive UUC patients than in HBsAg-negative UUC patients. Conclusion This is the first study to demonstrate that chronic HBV infection is strongly associated with UUC, at least in men. The urinary pH > 6 and staghorn stones were more common in UUC patients with chronic HBV infection.
