Epidemiology of urolithiasis in Spain: Review of published demographic data in the period 1977-2016.

CONCLUSIONS: The comprehensive review of studies on epidemiology in Spain constitutes a solid basis for future research about epidemiology of urolithiasis. PMID: 28300034 [PubMed - in process]

ConclusionsThe nonspecific symptoms of ureteral endometriosis can result in incorrect diagnosis, with renal damage as a result of prolonged hydronephrosis. A high index of suspicion and use of imaging modalities enable earlier diagnosis and preservation of renal function.

This study developed an in vitro system by co-culturing HK-2 cells with different concentration of hydroxyapatite (HAP) and/or macrophage cells to simulate the internal environment of urolithiasis as far as possible, investigating the regulatory effects of macrophage cells on HAP-induced expression of relative inflammatory factors of HK-2 cells. The control group (H group) was only comprised of HK-2 cells. Experimental groups included co-culturing HK-2 cells and macrophage cells (H  + M group), co-culturing HK-2 cells and HAP (H + A group), co-culturing macrophage cells and HAP (M +&thins...

Conclusions The management of lithiasis in the CAU setting follows a profile similar to that recognized in the European and American clinical guidelines, although there are interesting variations based on the practitioner's age and preferences. We identified potential areas for improvement in small-caliber PCNL and ultrasound-guided puncture.

The objective of the present study is to derive a model for the early detection of the type of kidney stone and the most influential parameters with the aim of providing a decision-support system. Information was collected from 936 patients with nephrolithiasis at the kidney center of the Razi Hospital in Rasht from 2012 through 2016. The prepared dataset included 42 features. Data pre-processing was the first step toward extracting the relevant features. The collected data was analyzed with Weka software, and various data mining models were used to prepare a predictive model. Various data mining algorithms such as the Bay...

The objective was to assess the frequency, the composition and the topography of papillary plugs in human kidneys. A total of 76 p apillae from 25 kidneys removed for cancer and without stones were analysed by immunohistochemistry combined with Yasue staining, field emission-scanning electron microscopy and Fourier transformed infrared micro-spectroscopy. Papillary tubular plugs have been observed by Yasue staining in 23/25 pat ients (92%) and 52/76 papillae (68%). Most of these plugs were made of calcium phosphate, mainly carbonated apatite and amorphous calcium phosphate, and rarely octacalcium phosphate pentahydrate. Ca...

The worldwide prevalence and risk factors for kidney stones in patients with fibrodysplasia ossificans progressiva (FOP) are unknown. We conducted a survey of 383 patient-members of the International Fibrodysplasia Ossificans Progressiva Association, comprising the entire global membership of the international FOP community. Two hundred seven patients from 31 nations and 6 continents (54%) responded. Nineteen of 207 respondents had kidney stones, revealing a worldwide prevalence of 9.2%. In a confirmatory follow-up study of subjects participating in a longitudinal FOP natural history study, 9 of 114 individuals reported a ...

AbstractMaintenance of flexible ureteroscopes can involve high costs and administrative burden. Instrument fragility necessitates eventual repair, rendering scopes inaccessible during refurbishment. We conducted a multi-institutional prospective cohort study to identify perioperative factors influencing flexible ureteroscope durability. Patients undergoing flexible ureteroscopy (URS) at six United States endourology centers were enrolled between August 2014 and June 2015. Surgeon self-reported concern and satisfaction with scope performance as well as upward and downward angles of deflection for each scope tip were measure...

Clinical suspicion of urolithiasis should be evaluated with low-dose computed tomography as the first-line imaging modality for nonpregnant, adult patients. A period of observation may be appropriate for ureteral stones less than 10  mm, and medical expulsive therapy may be beneficial for facilitating passage of distal ureteral stones. Regardless of stone type, patients should adhere to a low-sodium diet and attempt to achieve a urine volume of more than 2.5 L daily. Individuals with calcium stones should maintain a normal ca lcium diet, and if stones persist, citrate therapy or thiazide diuretics in the setting ...
