title: Papillary necrosis in renal allografts--report of 2 cases.
abstract: Two patients are reported in whom early and irreversible renal allograft rejection was associated with passage of necrotic papillary material in the urine. Evidence is presented for a causal relationship between rejection and medullary necrosis. Passage of a papilla is regarded as a definite indication for graft exploration.
