Hematuria associated with sickle cell trait during pregnancy.

Although sickle cell trait is usually considered a benign condition, it has frequently been associated with hematuria and an increased incidence of pyelonephritis. This case report highlights the complications that can occur with sickle cell trait in a pregnant patient. Pregnancy enhances the susceptibility for renal problems, and pregnant patients who develop complications require close monitoring for anemia, which can ultimately cause renal or uteroplacental insufficiency and pose a threat to the fetus. We would like to alert physicians doing routine antenatal care to serious complications that can arise in patients with a sickle cell trait.
