Acute tubulointerstitial nephritis and uveitis syndrome: A report on four adult cases.

Acute tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease, generally presenting in children and young women. The interstitial nephritis may precede, follow, or develop concurrent to the uveitis. We report the clinical features and outcomes of four adult patients, aged 41-70 years with the TINU syndrome.
