title: Renal papillary necrosis in sickle cell hemoglobinopathies.
abstract: Approximately 65 per cent of patients with clinical manifestations of S-hemoglobinopathies show urographically demonstrable changes of renal papillary necrosis, regardless of the presence of urinary symptoms. With a more precise excretory urographic technique these changes can be diagnosed with greater accuracy without the need for sophisticated equipment. Excretory urography should be performed routinely in the evaluation of all patients with manifestations of S-hemoglobinopathy in order to diagnose papillary necrosis before the onset of urological symptoms.
