Nephrolithiasis is a multifactorial disease affecting >10% of the population worldwide. In this chapter we discuss the pathophysiology of frequent kidney stone types, describe metabolic workup and preventative approaches commonly used in kidney stone formers and review urological techniques for stone removal. 0
A 45-year-old woman affected by MEN-1 syndrome with a history of bilateral nephrolithiasis due to parathyroid adenoma (primary hyperparathyroidism) and celiac disease presented to the nephrologist for recurrent episodes of renal colic and urinary passage of small stones with an unusual morphology despite previous surgical removal of the parathyroid adenoma. A complete diagnostic workup ought … Leggi tutto
Recent work in nephrolithiasis has benefited from 2 special kinds of imaging: endoscopic study of patient kidneys with high-quality instruments, and examination of stones with microscopic computed tomography (micro CT). The combination of these has provided new evidence that there is more than 1 mechanism by which stones are retained in the kidney until they … Leggi tutto
Chemical-colorimetric methods for kidney stones identification are widely adopted in most routine laboratories due to low cost with no need of instrumental analysis. Actually, kidney stones are well characterized with the Fourier transform infrared spectroscopy combined with Attenuated Total Reflection (ATR/FT-IR) that allows quick identification of chemical compounds into solid samples. Furthermore, Raman spectroscopy is … Leggi tutto
e Kidney stones are a common condition in the general population, however, high-quality evidence for its management is scarce. We propose the creation of an international network with the aim of sharing practice patterns and patient data towards an improvement of our knowledge of the disease. Our survey highlights the potential for the creation of … Leggi tutto
Renal stones are common and are usually secondary to risk factors affecting the solubility of substances in the urinary tract. Primary, that is genetic, causes are rare but nevertheless are important to recognise so that appropriate treatments can be instigated and the risks to other family members acknowledged. A brief overview of the investigation of … Leggi tutto
According to the Randall plaque theory, urinary crystals may attach to focal interstitial deposits of calcium phosphate (CaP), localized in the tip of the renal papillae. The aim of this prospective study was to evaluate the feasibility and safety of papillary biopsy, performed during ureterorenoscopy (URS) or percutaneous nephrolithotomy (PCNL), to obtain, in 0
A symposium on kidney stones and mineral metabolism held on December 2017 in Brussels, Belgium was the first international multidisciplinary conference of the International Collaborative Network on Kidney Stones and Mineral Metabolism. This meeting addressed epidemiology, underlying pathophysiological mechanisms, genetics, pathological, as well as clinical and research topics. The participants included clinicians and recognized experts … Leggi tutto
