Abstract
BACKGROUND: Sickle cell trait is not completely benign, and some renal complications can occur. The baseline rate of admission for gross hematuria in normal males carrying the sickle cell trait is 2%. CASE PRESENTATION: A 35-year-old non-smoking African man experienced a 2-week history of painless, profuse and persistent gross hematuria. Laboratory tests showed normal renal function, hematuria and mild proteinuria. Abdominal ultrasonography and computed tomography angiography revealed no renal abnormalities; the bladder appeared pristine under cystoscopy. The diagnosis of sickle cell trait associated with gross hematuria was made using hemoglobin electrophoresis; renal biopsy and its complications were avoided. Urine was clear after 2 weeks of oral hydration and gamma epsilon-aminocaproic acid. CONCLUSION: Hemoglobin electrophoresis should be performed in cases of gross hematuria. Coupled with other non-invasive evaluation, this could avoid renal biopsy and its associated complications.
