[Gross hematuria in sickle cell disease at Tokoin teaching hospital in Lomé (Togo)].

The renal complications of sickle cell anemia are well known. Gross hematuria is one of these, although it is associated more often with the sickle cell trait than with the disease. Nonetheless, in Togo, where the frequency of S gene is 16%, hematuria is rarely report in people with this gene. We describe 3 cases of gross hematuria in patients with sickle cell disease: primary hematuria associated with sickle cell disease. We found no promoting factors in our patients. The course was short, and after 4 to 15 years, there have been no recurrences.
