Retention and growth of urinary stones: insights from imaging

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

Caratterizzazione dei calcoli urinari mediante spettroscopia Raman e spettroscopia infrarossa in trasformata di Fourier a confronto col metodo chimico-colorimetrico

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

Practice patterns of kidney stone management across European and non‑European centers: an in‑depth investigation from the European Renal Stone Network (ERSN)

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

Genetic defects underlying renal stone disease

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

Percutaneous and Transureteral Biopsies of Renal Papillae: Safe and Appropriate Procedures for In Vivo Histologic Analysis in Stone Formers

 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

Meeting report of the “Symposium on kidney stones and mineral metabolism: calcium kidney stones in 2017”

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
