March Hemoglobinuria

March hemoglobinuria, also known as march hematuria, occurs when blood is seen in the urine after repetitive impacts on the body, particularly affecting the feet (such as running on a hard road or Kendo) and hands (e.g. Conga or Candombe drumming). The word "march" is in reference to the condition arising in soldiers who have been marching for long periods; the condition was first documented in 1881.
