Inhibiting inflammation and modulating oxidative stress in oxalate-induced nephrolithiasis with the Nrf2 activator dimethyl fumarate.

Free Radic Biol Med 2018 Dec 29;134:9-22. Epub 2018 Dec 29.

Department and Institute of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China.

Hyperoxaluria induces oxidative stress, and inflammation causes renal epithelial cell injury in nephrolithiasis, suggesting that reduced oxalate toxicity may be beneficial. This study aimed to investigate whether nuclear factor (erythroid-derived 2)-like 2 (Nrf2, also called Nfe2l2) induced by dimethyl fumarate (DMF) could protect renal epithelial cells against oxalate-mediated injury both in vivo and in vitro. Glyoxylic acid monohydrate was intraperitoneally injected into Sprague-Dawley rats with or without intragastric administration of DMF. Read More

Urinary proteome in inherited nephrolithiasis.

Urolithiasis 2019 Feb 18;47(1):91-98. Epub 2018 Dec 18.

Chair of Nephrology, Department of Translational Medicine, University of Campania "Luigi Vanvitelli", Naples, Italy.

In the last decades, proteomics has been largely applied to the Nephrology field, with the double aim to (1) elucidate the biological processes underlying renal diseases; (2) identify disease-specific biomarkers, predictor factors of therapeutic efficacy and prognostic factors of disease progression. Kidney stone disease, and in particular, inherited nephrolithiasis (INL) are not an exception. Given the multifactorial origin of these disorders, the combination of genomics and proteomics studies may complement each other, with the final objective to give a global and comprehensive mechanistic view.

Recent advances in the identification and management of inherited hyperoxalurias.

Urolithiasis 2019 Feb 10;47(1):79-89. Epub 2018 Dec 10.

Mayo Clinic, Rochester, MN, USA.

Primary hyperoxaluria (PH) is caused by genetic mutations resulting in oxalate overproduction leading to nephrolithiasis, nephrocalcinosis, extrarenal manifestations, chronic kidney disease, and end-stage renal disease. Advances in genetic testing techniques have improved our ability to efficiently and effectively obtain a definitive diagnosis of PH as well as easily screen at-risk family members. Similarly, advances in technologies related to intervening at the genetic and molecular level promise to change the way we treat patients with PH. Read More

Living kidney donation from people at risk of nephrolithiasis, with a focus on the genetic forms.

Urolithiasis 2019 Feb 23;47(1):115-123. Epub 2018 Nov 23.

UOC Nefrologia, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

Deciding whether to accept a donor with nephrolithiasis is a multifaceted task because of the challenge of finding enough suitable donors while at the same time ensuring the safety of both donors and recipients. Until not long ago, donors with a history of renal stones or with stones emerging during screening on imaging were not considered ideal, but recent guidelines have adopted less stringent criteria for potential donors at risk of stones. This review goes through the problems that need to be approached to arrive at a wise clinical decision, balancing the safety of donors and recipients with the need to expand the organ pool.

Nephrolithiasis secondary to inherited defects in the thick ascending loop of henle and connecting tubules.

Urolithiasis 2019 Feb 20;47(1):43-56. Epub 2018 Nov 20.

Division of Nephrology and Hypertension, Inselspital, Bern University Hospital, University of Bern, Freiburgstrasse 15, 3010, Bern, Switzerland.

Twin and genealogy studies suggest a strong genetic component of nephrolithiasis. Likewise, urinary traits associated with renal stone formation were found to be highly heritable, even after adjustment for demographic, anthropometric and dietary covariates. Recent high-throughput sequencing projects of phenotypically well-defined cohorts of stone formers and large genome-wide association studies led to the discovery of many new genes associated with kidney stones.

Calcium-sensing receptor: evidence and hypothesis for its role in nephrolithiasis.

Urolithiasis 2019 Feb 16;47(1):23-33. Epub 2018 Nov 16.

Nephrology and Dialysis Unit, Postgraduate School of Nephrology, IRCCS San Raffaele Scientific Institute, Vita Salute University, 20132, Milan, Italy.

Calcium-sensing receptor (CaSR) is a plasma-membrane G protein-coupled receptor activated by extracellular calcium and expressed in kidney tubular cells. It inhibits calcium reabsorption in the ascending limb and distal convoluted tubule when stimulated by the increase of serum calcium levels; therefore, these tubular segments are enabled by CaSR to play a substantial role in the regulation of serum calcium levels. In addition, CaSR increases water and proton excretion in the collecting duct and promotes phosphate reabsorption and citrate excretion in the proximal tubule. Read More

Does the use of fluoroscopy really affect the success rate of retrograde intrarenal surgery?

Arch Esp Urol 2018 Nov;71(9):772-781

Department of Urology. Kecioren Research and Training Hospital. Ankara. Turkey.

Introduction: Fluoroscopy is used for access sheath insertion and postoperative control during retrograde intrarenal surgery (RIRS) operation but with this technique both patient and operation team are exposed to radiation. The use of fluoroscopy is disadvantage for both patient and surgeon. Considering results of recent studies, it is clearly seen that fluoroscopy doesn't affect the success and complication rates of RIRS. Read More

Renal stones in two children with two rare etiologies.

Saudi J Kidney Dis Transpl 2018 Sep-Oct;29(5):1203-1206

Department of Pediatric Nephrology, Sheikh Khalifa Medical City, Abu Dhabi, UAE.

The incidence of urolithiasis in children has shown an increase in recent years which may be attributed to changing dietary patterns, sedentary lifestyles, and obesity. Among the various etiologies for renal stones in children, two rare entities worth mentioning are cystinuria and 2, 8-dihydroxyadenine (DHA) urolithiasis. Cystinuria is an inherited cause of nephrolithiasis which occurs due to impaired cystine reabsorption in the renal proximal tubule. Read More

Radiation effect on cathodoluminescence and thermoluminescence emission of Ca-rich oxalates from the human body.

Luminescence 2018 Dec 31;33(8):1438-1444. Epub 2018 Oct 31.

CSIC. Museo Nacional de Ciencias Naturales, C/José Gutiérrez Abascal 2, Madrid, Spain.

The radiation effect of luminescence emission of Ca-rich oxalate biogenic materials (gallbladder and renal calculi) and a commercial standard sample (CaC O ·H O) is reported. The samples were characterized by environmental scanning electron microscopy, energy dispersive X-ray spectroscopy, thermogravimetric and differential thermal analyses, display complex cathodoluminescence (CL) and thermoluminescence (TL) glow emissions. CL spectra (in the UV-infrared range) displayed non-well defined peaks, and exhibited emission at: (i) higher energies (300-490 nm) mainly associated with non-bridging oxygen hole centers, oxygen-deficient centers and peroxy intrinsic defects, regardless of the sample; and (ii) higher, narrow and sharp wavebands, in the red region, probably induced by the presence of traces of Sm ( G → H transition) and/or Tb ( D → F transition) only for mineral-like materials in the human body.

Antepartum nephrolithiasis and the risk of preterm delivery.

Urolithiasis 2018 Oct 27. Epub 2018 Oct 27.

Department of Urology, Loyola University Medical Center, Maywood, IL, 60153, USA.

Antepartum nephrolithiasis presents a complex clinical scenario which often requires an intervention such as ureteral stent or percutaneous nephrostomy tube (PCNT) placement, especially in the setting of urinary tract infection (UTI). We assess the risk of UTI and preterm labor in the setting of antepartum nephrolithiasis. A retrospective review of an administrative dataset for California and Florida was performed, which included pregnant women admitted for a delivery between 2008 and 2011. Read More

Asian J Urol 2018 Oct 26;5(4):235-242. Epub 2018 Jun 26.

Universidade Federal de São Paulo, Nephrology Division, São Paulo, Brazil.

Considering the variation in metabolic evaluation and medical management of kidney stone disease, this consensus review was created to discuss the metabolic activity of nephrolithiasis, define the difference between single and recurrent stone formers, and develop a schema for metabolic and radiologic follow-up. A systematic review of the literature was performed to identify studies of metabolic evaluation and follow-up of patients with nephrolithiasis. Both single and recurrent stone formers share many similarities in metabolic profiles. Read More
