The pathophysiology of nephrolithiasis is not fully understood. The pioneering work of
Alexander Randall in the 1940s sought to clarify our understanding of stone formation. This …

The prevalence of renal stones, or nephrolithiasis, has been increasing consistently over the
past few decades. Changes in lifestyles and dietary habits of the population may be …

Résumé Alexander Randall described eight decades ago a heterogeneous nucleation
process at the tip of the renal papillae giving birth to calcium oxalate stones. Kidney stones …

Randall's plaque is microscopically a plaque of calcium deposited in the interstitial tissue of
the renal papilla. These plaques are thought to serve as a nidus for urinary stone formation …

Recent work in nephrolithiasis has benefited from two special kinds of imaging: Endoscopic
study of patient kidneys with high quality instruments, and examination of stones with …

Dr. Evans and his colleagues provided a summary of their work investigating various types
of stones and proposed four basic mechanisms for their formation. Idiopathic CaOx stones …

Abstract Purpose: Papillary" Randall's plaques" are theorized to act as nidi for urinary stone
formation. The aim of this study was to document the presence, pattern and distribution of …

Randall's plaque (RP) deposits seem to be consistent among the most common type of
kidney stone formers, idiopathic calcium oxalate stone formers. This group forms calcium …
