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.
