urea has been researched along with Hematochezia in 50 studies
pseudourea: clinical use; structure
isourea : A carboximidic acid that is the imidic acid tautomer of urea, H2NC(=NH)OH, and its hydrocarbyl derivatives.
Hematochezia: The passage of bright red blood from the rectum. The blood may or may not be mixed with formed stool in the form of blood, blood clots, bloody stool or diarrhea.
