[The TINU syndrome in children (tubular interstitial nephritis with uveitis)]

Acute tubulo interstitial nephritis accompanied by uveitis is identified as TINU syndrome. The TINU syndrome is isolated from other forms of tubulo interstitial nephritis by the particular symptomatology and course: the nephropathy is almost always reversible, the uveitis tends towards relapses. The histopathologic findings are compatible with disturbance of cellular immunity, but the exact etiology is still unknown. In general, the outcome is favourable, but follow up, at least as long as there are signs of nephropathy, is necessary.
