The impact of ambient temperature on the incidence of urolithiasis: a systematic review and meta-analysis.

The impact of ambient temperature on the incidence of urolithiasis: a systematic review and meta-analysis. Scand J Work Environ Health. 2019 Nov 20;: Authors: Zhang Y, Long G, Ding B, Sun G, Ouyang W, Liu M, Ye Z, Xu H, Li H Abstract Objective This review aimed to confirm the association between ambient temperature and incidence of urolithiasis and evaluate the impact thereof. Methods A systematic literature review was performed up to September 2019 using multiple databases. The effect of temperature on urolithiasis risk was assessed using risk ratio (RR). Pearson correlation coefficient (Pearson's r) was used to evaluate the linear association between ambient temperature and urolithiasis incidence. The non-linear association between climatic temperature and the urolithiasis incidence was also evaluated. Results Twenty-four studies related to the temperature and urolithiasis risk in 14 different countries or regions of five continent involving over 2.5 million cases were included in the meta-analysis. High climatic or workplace temperature was a significant risk factor of urolithiasis. The weighted correlation coefficient (Pearson's r) of monthly temperature and urolithiasis risk was 0.49 [95% confidence interval (CI) 0.40-0.57], a moderate correlation (0.4

AbstractPurposeTo assess a novel low-dose CT-protocol, combining a 150  kV spectral filtration unenhanced protocol (Sn150 kVp) and a stone-targeted dual-energy CT (DECT) in patients with urolithiasis.Methods232 (151 male, 49  ± 16.4 years) patients with urolithiasis received a low-dose non-contrast enhanced CT (NCCT) for suspected urinary stones either on a third-generation dual-source CT system (DSCT) using Sn150 kVp (n = 116, group 1), or on a second-generation DSCT (n = 116 group 2) using single energy (SE) 120 kVp. For group 1, a subsequent dual-...

Abstract PURPOSE: The aim of the study was to evaluate the predictive value of nephrolithometric scoring systems used to predict the complexity of renal stones for the outcomes of retrograde intrarenal surgery (RIRS). MATERIALS AND METHODS: A total of 81 patients who underwent RIRS for nephrolithiasis between January 2013 and October 2017 were reviewed in this retrospective study. Guy's Stone Score (GSS), the S.T.O.N.E., Clinical Research Office of the Endourologic Society (CROES), and Seoul National University Renal Stone Complexity (S-ReSC) nephrolithometry scores were assessed by same researcher for each p...

ConclusionsFT is more effective than cefuroxime, which is commonly used during the perioperative period of urinary stones, and exerts a high antibacterial effect on these internal bacteria, and effectively reduces the probability of infection and sepsis after urinary stone surgery. FT can be used as an antibiotic during the perioperative period of urinary stones.

CONCLUSIONS: The incidence of de novo nephrolithiasis in ESRD patients on HD was 10.5%. Increased serum uric acid, decreased serum magnesium and ionized calcium, and absence of hypertension were associated with increased stone-formation in ESRD patients on HD.

ConclusionsGiant parathyroid adenoma is a rare cause of primary hyperparathyroidism and usually presents symptomatically  with high calcium and parathyroid hormone levels. Giant parathyroid adenoma is diagnosed by imaging and laboratory studies. Management is typically surgical, aiming at complete resection. Patients usually recover with no long-term complications or recurrence.
