Hematuria and sickle cell disorders.

To examine the relationship between gross hematuria and sickle cell disorders, all patients admitted to Grady Memorial Hospital with the diagnosis of a sickle cell disorder during a 14-month period were reviewed. Of 115 such patients, 65% had sickle cell disease and 35% had sickle cell trait. None of the former but seven of the latter group had gross hematuria. Mean age of the seven was 30 years. Comprehensive examinations and laboratory studies showed that all were free of concomitant disease. Physical findings, diagnostic modalities, and treatment were reviewed. Findings suggest that conservative therapy (bed rest, hydration, and diuresis) is usually effective.
