Bladder trauma in the long-distance runner: "10,000 metres haematuria".
Profuse, short-lived haematuria occurring as an occasional event in a number of long-distance runners has been found to originate from lesions in the bladder. These lesions are either ecchymosis or frank contusions which have a typical distribution. They are sited on the inter-ureteric bar, the posterior half of the rim of the internal meatus and on the posterior bladder wall in which position there is "mirroring" of the trigonal lesions. The possible mode of injury is discussed.
