Urinary retention in sickle cell syndromes

Four patients with sickle cell disease noted the development of urinary retention during an acute painful crisis. The acute urinary retention resolved with improvement in the painful sickle cell crisis. No evidence of anatomic urologic defect, systemic neurologic abnormality, or infection was documented in these patients. Patients with sickle cell disease in painful crisis should be observed for signs of acute urinary retention.
