Hematuria or haematuria is defined as the presence of blood or red blood cells in the urine. [1] "Gross hematuria" occurs when urine appears red, brown, or tea-colored due to the presence of blood. Hematuria may also be subtle and only detectable with a microscope or laboratory test. [2]
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes , which help keep the bite area unclotted long enough for the animal to obtain blood.
The benefits versus risks of restarting blood thinners such as aspirin or warfarin and anti-inflammatories such as NSAIDs need to be carefully considered. [4] If aspirin is needed for cardiovascular disease prevention, it is reasonable to restart it within seven days in combination with a PPI for those with nonvariceal upper GI bleeding.
BPH is the most common and is found in older intact (not neutered) dogs. Signs include blood in the urine and straining to urinate and defecate. Castration is the treatment of choice. [161] Prostatis can be associated with BPH. Bacteria causing prostatitis include E. coli, Staphylococcus spp., Streptococcus spp., and Mycoplasma spp. [162]
Laboratory testing of urine samples now can be performed with dipsticks that indicate immune system responses to infection, as well as with microscopic analysis of samples. The presence of hematuria, or blood in the urine, may indicate acute UTIs, kidney disease, kidney stones, inflammation of the prostate (in men), endometriosis (in women), or ...
Microhematuria, also called microscopic hematuria (both usually abbreviated as MH), is a medical condition in which urine contains small amounts of blood; the blood quantity is too low to change the color of the urine (otherwise, it is known as gross hematuria).
In dogs and cats, eggs of Capillaria plica are released in the urine of the mammalian definitive host. First stage larvae (L1) develop within the eggshell in 30–36 days. When eaten by the intermediate host-- earthworms of the genera Lumbricus or Dendrobaena—the L1 larvae hatch in the earthworm's intestine.
Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine. [1] The condition is caused by excessive intravascular hemolysis , in which large numbers of red blood cells (RBCs) are destroyed, thereby releasing free hemoglobin into the plasma . [ 2 ]
