Medical literature describes it as an adult disease in the pre-antibiotic era, and nowadays, is a rare complication. This study reports the case of a patient with nephrolithiasis who developed a nephropulmonary fistula resulting in the migration of renal coralliform stones to the lung parenchyma.

Calcium sensing receptor regulate claudin-14 via PKA-STAT3 pathway in rat model of nephrolithiasis.

Background: The calcium-sensitive receptor (CaSR) has been identified as a key factor in the formation of kidney stones. A substantial body of research has illuminated the function of CaSR in stone formation with respect to oxidative stress, epithelial injury, crystal adhesion, and stone-associated proteins. Nevertheless, as a pivotal molecule in renal calcium excretion, its pathway that contributes to stone formation by regulating calcium supersaturation remains underexplored.
