Introduction
Tubulointerstitial nephritis and uveitis (TINU) syndrome, which is characterized by a combination of acute interstitial nephritis (AIN) and uveitis, is predominant among adolescent girls. Uveitis and pyelonephritis appear at various timepoints, with studies suggesting that more than half of the patients develop ocular symptoms later than AIN [1]. Therefore, early disease recognition may be challenging. This report also describes the reporting and diagnostic problems of TINU cases in female patients whose renal features are primarily due to drug-induced AIN.
