Bilateral Renal Infarction Secondary to Hypertrophic Cardiomyopathy.

Cureus 2019 Feb 11;11(2):e4046. Epub 2019 Feb 11.

Internal Medicine, Medstar Union Memorial Hospital, Baltimore, USA.

Bilateral renal infarction is a rare phenomenon which can be difficult to diagnose because the symptoms may often mimic renal calculi, infection, muscle inflammation, genital diseases, myocardial infarction, or ischemia. We present the case of a 55-year-old male patient who presented with non-radiating, left-sided flank pain associated with nausea and vomiting. A computed tomography (CT) scan of the abdomen and pelvis with contrast demonstrated bilateral renal infarction. Read More

Selective protein enrichment in calcium oxalate stone matrix: a window to pathogenesis?

Urolithiasis 2019 Apr 16. Epub 2019 Apr 16.

Department of Medicine/Division of Nephrology, Medical College of Wisconsin, 9200 W Wisconsin Avenue, Milwaukee, WI, 53226, USA.

Urine proteins are thought to control calcium oxalate stone formation, but over 1000 proteins have been reported in stone matrix obscuring their relative importance. Proteins critical to stone formation should be present at increased relative abundance in stone matrix compared to urine, so quantitative protein distribution data were obtained for stone matrix compared to prior urine proteome data. Matrix proteins were isolated from eight stones (> 90% calcium oxalate content) by crystal dissolution and further purified by ultradiafiltration (> 10 kDa membrane). Read More

Assessing Cost-Effectiveness of New Technologies in Stone Management.

Urol Clin North Am 2019 May 4;46(2):303-313. Epub 2019 Mar 4.

Urology, University of California San Francisco, San Francisco, CA, USA.

Diagnosis, treatment, and follow-up are all influential in determining the overall cost to the health care system for kidney stones. New innovations in the field of nephrolithiasis have been abundant, including disposable ureteroscopes, ultrasound-guided approaches to percutaneous nephrolithotomy, and advanced laser lithotripters. Identifying cost-effective treatment strategies encourages practitioners to be thoughtful about providing value-based high-quality care and remains on important principle in the treatment of urinary stone disease.

Dual-Energy CT in Children: Imaging Algorithms and Clinical Applications.

Radiology 2019 May 26;291(2):286-297. Epub 2019 Mar 26.

From the Mallinckrodt Institute of Radiology, Washington University School of Medicine, 510 S Kingshighway Blvd, St Louis, Mo 63110 (M.J.S.); and Siemens Healthineers, Malvern, Pa (J.C.R.G.).

Dual-energy CT enables the simultaneous acquisition of CT images at two different x-ray energy spectra. By acquiring high- and low-energy spectral data, dual-energy CT can provide unique qualitative and quantitative information about tissue composition, allowing differentiation of multiple materials including iodinated contrast agents. The two dual-energy CT postprocessing techniques that best exploit the advantages of dual-energy CT in children are the material-decomposition images (which include virtual nonenhanced, iodine, perfused lung blood volume, lung vessel, automated bone removal, and renal stone characterization images) and virtual monoenergetic images.

Center for Pediatric Clinical Effectiveness, The Children's Hospital of Philadelphia, Philadelphia, PA, 19104, USA.

Previous studies assumed a uniform relationship between heat and kidney stone presentations. Determining whether sex and other characteristics modify the temperature dependence of kidney stone presentations has implications for explaining differences in nephrolithiasis prevalence and improving projections of the effect of climate change on nephrolithiasis. We performed an aggregated case-crossover study among 132,597 children and adults who presented with nephrolithiasis to 68 emergency departments throughout South Carolina from 1997 to 2015.

Medicine (Baltimore) 2019 Mar;98(10):e14796

Department of Urology, West China Hospital, Sichuan University, Xiang, Chengdu.

Background: Some trials have stated that there is no benefit to tamsulosin administration for clearing ureteral stones, which is contrary to previous studies. To confirm the efficacy of tamsulosin for treating symptomatic ureteral stones, we performed this review.

Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify all studied variables, including tamsulosin, urinary stones, expulsion, and side effects. Read More

Changes in separate renal function in patients who underwent minimally invasive renal stone surgery according to the preoperative functional deterioration.

Sci Rep 2019 Mar 5;9(1):3610. Epub 2019 Mar 5.

Department of Urology, SMG-SNU Boramae Medical Center, Seoul, Korea.

The significant predictors for the postoperative deterioration of separate renal function after minimally invasive stone surgery were investigated in the present prospective and observational study. A total of 117 consecutive patients who underwent retrograde intrarenal surgery or mini-percutaneous nephrolithotomy for renal calculi >10 mm were included in the present study. Perioperative changes in separate renal function were evaluated with Technetium-99m-Diethylene TriaminePenta acetic acid scan prior to intervention and at postoperative 3 months. Read More

Contemporary Analysis of Calculous Nephrectomy Utilization and Outcomes in the United States.

J Endourol 2019 Apr 10. Epub 2019 Apr 10.

2 Division of Urology, Department of Surgery, Rutgers-Robert Wood Johnson Medical School, New Brunswick, New Jersey.

Introduction: Calculous nephrectomy was a mainstay of treatment of complex upper tract stone disease up until the 1970s, but data on its contemporary utilization in the current era of rising rates of stone disease are lacking. We characterized the nationwide utilization and outcomes for calculous nephrectomy in the United States.

Patients And Methods: The National/Nationwide Inpatient Sample databases for 2001 to 2014 were queried for adults with a principal diagnosis of upper urinary tract calculi (UUTCs), who underwent nephrectomy as well as other inpatient surgeries for UUTCs. Read More

Scanning electron microscopy in analysis of urinary stones.

Scand J Clin Lab Invest 2019 May 1;79(3):208-217. Epub 2019 Mar 1.

b Department of Clinical Biochemistry and Haematology, Faculty of Medicine , Charles University and University Hospital , Pilsen, Czech Republic.

Urolithiasis is a frequent and in many cases serious disease. Proper analysis of kidney stone composition is crucial for appropriate treatment and prevention of disease recurrence. In this work, scanning electron microscopy (SEM) coupled with energy-dispersive spectroscopy was applied for a study of 30 samples covering the most common types of human kidney stones. Read More

Gac Med Mex 2019 ;155(1):52-57

Instituto Mexicano del Seguro Social, Centro Médico Nacional Siglo XXI, Hospital de Especialidades.

Introduction: Success in percutaneous nephrolithotomy (PCNL) is defined as a stone-free status; however, major complications are highly common and have been reported as a secondary outcome.

Objective: To propose a new definition of PCNL success that comprises a stone free rate without major complications and a risk scale to predict this outcome.

Methods: Historical cohort of patients undergoing PCNL. Read More

Net Acid Excretion and Urinary Organic Anions in Idiopathic Uric Acid Nephrolithiasis.

Clin J Am Soc Nephrol 2019 Mar 11;14(3):411-420. Epub 2019 Feb 11.

Department of Internal Medicine,

Background And Objectives: Idiopathic uric acid nephrolithiasis, which is closely associated with obesity and the metabolic syndrome, is increasing in prevalence. Unduly acidic urine pH, the quintessential pathophysiologic feature of this disease, is in part explained by inadequate excretion of the principal urinary buffer ammonium. The role of net acid excretion in the pathogenesis of uric acid nephrolithiasis is incompletely understood. Read More
