[Pathophysiology and diagnosis of nephrocalcinosis].
Nephrocalcinosis is the result of a myriad of hereditary or acquired diseases in the calcium, phosphate or oxalate metabolism that lead to deposition of calcium containing precipitates within the kidney. Nephrocalcinosis and nephrolithiasis are pathophysiologically tightly related and often co-exist. In the case of recurrent nephrolithiasis, nephrocalcinosis has to be excluded. Stone analysis can yield important clues to the underlying disease process. The best way to diagnose nephrocalcinosis and an accompanying nephrolithiasis is by native computer tomography scans. Untreated, nephrocalcinosis will lead to a progressive decline in renal function and eventually to end stage renal disease. Thus, for each case, the underlying disease process has to be determined and a causative therapy initiated.
