title: Recurrent hematuria in 4 white patients with sickle cell trait.
abstract: Extensive investigations failed to disclose the etiology of recurrent gross hematuria in 4 white patients of Algerian descent. Hemoglobin electrophoresis revealed sickle cell trait in all cases. The hematuria ceased after bed rest and hydration in 3 patients, and following partial nephrectomy after visualization of the bleeding site at operative nephroscopy in 1. We recommend that hemoglobin electrophoresis be considered when evaluating every patient, black or white, presenting with unexplained hematuria.
