[Yersiniosis as a cause of acute tubulointerstitial nephritis and acute renal failure--case report].

Tubulointerstitial nephritis (TN) is a heterogenous disease, where disturbances of the interstitial tissue and renal tubules are found. Different immunological and nonimmunological mechanisms initiated by infectious and non-infectious factors may lead to TN. A case of 13-years-old girl with primary diagnosis of acute pyelonephritis is presented.
