“…Commentary Although 70% of patients have asymptomatic stones on US, hematuria, flank/abdominal pains, prior stone episodes, nausea and vomiting are common signs to suspect stone existence (LE:1, GR:A). 85,86 In addition, habitual behavior, including a larger amount of diet and alcohol consumption, positive family history, and less physical activity, is associated with the risk for urinary stone disease (LE:3, GR:A). 30,37,[87][88][89][90] Positive family history, younger age at onset and having two or more previous stone episodes increase the prevalence of stone recurrence (LE:1, GR:A).…”

The Urological Association of Asia clinical guideline for urinary stone disease

et al. 2019

The Urological Association of Asia, consisting of 25 member associations and one affiliated member since its foundation in 1990, has planned to develop Asian guidelines for all urological fields. The field of stone diseases is the third of its guideline projects. Because of the different climates, and social, economic and ethnic environments, the clinical practice for urinary stone diseases widely varies among the Asian countries. The committee members of the Urological Association of Asia on the clinical guidelines for urinary stone disease carried out a surveillance study to better understand the diversity of the treatment strategy among different regions and subsequent systematic literature review through PubMed and MEDLINE database between 1966 and 2017. Levels of evidence and grades of recommendation for each management were decided according to the relevant strategy. Each clinical question and answer were thoroughly reviewed and discussed by all committee members and their colleagues, with suggestions from expert representatives of the American Urological Association and European Association of Urology. However, we focused on the pragmatic care of patients and our own evidence throughout Asia, which included recent surgical trends, such as miniaturized percutaneous nephrolithotomy and endoscopic combined intrarenal surgery. This guideline covers all fields of stone diseases, from etiology to recurrence prevention. Here, we present a short summary of the first version of the guideline – consisting 43 clinical questions – and overview its key practical issues.

Purpose:To explore the role of stone fragment and ureteric stent in process of intermittent gross hematuria (IGH), discuss the definition of ureteral stent related symptoms (USS) in a setting of lithotripsy and clinical outcomes of IGH. , patients with completed one month follow up after lithotripsy were collected. Based on whether occurrence of IGH, demographics, stent information and clinical outcomes were mainly analyzed.Results: A total of 258 consecutive patients were eventually analyzed, among which 97 patients (37.6%) suffered from IGH. Compared to patients without symptom of IGH, preoperative potassium level (3.89±0.43mmol/L vs. 4.02±0.42mmol/L, p=0.01), initial stone free rate (SFR, 50.52% vs. 68.32%, p=0.007) and potassium citrate application (11.34% vs. 4.55%, p=0.04) were found statistically different in univariate analysis. In multivariate logistic analysis, preoperative potassium level (OR: 0.39, CI: 0.19-0.76, p=0.007), potassium citrate (OR: 2.96, CI: 1.07-8.73, p=0.04), initial SFR (OR: 0.42, CI: 0.24-0.74, p<0.001), and hospital stay (OR: 0.94, CI: 0.89-0.99, p=0.045) were independent risk factors, rather than stent size and stent position. Hemoglobin change, stone area reduction and SFR in one-month follow-up were similar between groups, but more outpatient consultations were found in hematuria group (20 vs. 3, p<0.001), among which 2 patients were readmitted for severe ongoing hematuria. Conclusions:Stone fragment, rather the size or length of ureteral stent, is the independent risk factors of IGH. Definition of USS is not suitable for IGH after lithotripsy, and a comprehensive inform and enough rest would reduce the unnecessary medical consultations.

“…The disease is very likely to cause significant pain for the individual, leading to a substantial negative impact on society, work environments, and healthcare systems. Management of the disease in the employed population within the United States was estimated to cost $5 billion dollars in the year 2000 [4,5]. Urolithiasis has been associated with high-risk diseases, including chronic kidney disease [6], cardiovascular disease [7], hypertension [8], obesity [8,9], diabetes [10], and end-stage renal failure [11,12].…”

“…Despite significant progress in modern medicine, especially in developed countries, the prevalence and recurrence rate of urolithiasis is still increasing worldwide, with 50% more cases over the past 10 years; its occurrence in 2017 was more than twice that of 1994 [1,2,5]. Furthermore, the high cost of clinically available methods of urolithiasis diagnosis and treatment, as well as some of the side effects of currently administered drugs, have induced greater public utilization of traditional herbal medicine.…”

Comparative spectroscopic analysis of nordihydroguaiaretic acid and related natural products to inhibition of calcium oxalate calculi

The prevalence of urolithiasis is still increasing worldwide. The goal of this study is to achieve a better understanding, from a comparative spectroscopic perspective, of the differences provided by chemical and natural products to the inhibitory processes of calculi formation. The research presented here places primary emphasis on the assessment of nordihydroguaiaretic acid (NDGA), the main chemical extract of the plant Larrea Tridentata, as a preventative to calcium oxalate crystal formation. It is also a logical continuation of our previous efforts using a traditional medicine approach to study such prevention. Complementary Raman and Fourier transformed infrared (FTIR) absorption analysis were used to provide a complete overview of morphological changes of calcium oxalate crystals, which were grown without and with the addition of NDGA at different concentrations. A gel diffusion technique was employed for sample preparation. Our results from both Raman and FTIR spectroscopies demonstrate that no structural transformation from a monohydrate to dehydrate occurs upon crystallization with NDGA, as we previously reported for the use of the natural plant infusion. Calculi synthesized with NDGA shows a distorted monohydrate morphology. Different effects inhibitory to calcium oxalate calculi formation are observed and analyzed here using chemical and natural extracts. If magnesium is the key to this difference, this study confirms its importance, not only in hundreds of metabolic pathways, but also in nephrological ones.
