March hematuria
Encyclopedia
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.
s causing hemolysis
. Free haemoglobin released from lysed red blood cells is filtered into the urine. Defects in red blood cell membrane proteins have been identified in some of these patients.. The dead RBC's
are filtered by the glomerulus and are removed from the body. Due to destruction of a large number of RBC's, a large number of damaged blood cells are filtered out of the body at the same time, making the urine have noticeable amounts of hemoglobin in solution.
(which itself may be called "exertion hematuria"), proteinuria
, and cylinduria. However, athletic nephritis may be secondary to the hemoglobin load on the kidneys caused by the hemolysis in march hemoglobinuria. In most persons the effects of athletic nephritis are transient and disappear within hours to days after the end of exercise.

Prognosis
The situation usually lasts for a day or two. No specific medication is required. This condition usually goes unnoticed, except by those with a history of hematuria. March haemoglobinuria is usually not life threatening.Relation to athletic nephritis

Proteinuria
Proteinuria means the presence of anexcess of serum proteins in the urine. The protein in the urine often causes the urine to become foamy, although foamy urine may also be caused by bilirubin in the urine , retrograde ejaculation, pneumaturia due to a fistula, or drugs such as pyridium.- Causes...
