Microscopic hematuria is the medical term for excess traces of microscopic blood in urine. This urinary symptom is discovered after a urine sample is tested. Microscopic hematuria means there is a more than an acceptable amount of blood in the urine although it can’t be seen with the naked eye. Hematuria means blood in urine and microhematuria is a shortened form of microscopic hematuria. Once microscopic hematuria has been found you will be directed to visit urology specialists to determine the causes. When you can see blood in the urine it is called gross hematuria. You would probably be surprised to know that it’s normal to have a couple million red blood cells in urine every day. Any irregular levels of microscopic blood are usually detected through a urinalysis which is part of a routine physical. Even though the microscopic blood may seem inconsequential, any type of bloody urine can be a sign of a larger underlying problem.
Microscopic hematuria can be attributed to many urological conditions and may be a bladder symptom or prostate symptom . You could have kidney stones that cause the microscopic blood in urine. Blood clots caused by a bladder infection or cancer bladder invasion, can easily be seen in urine. Blood clots in urine can create obstructions and cause other urinary problems, such as urinary retention, to develop. Excess amounts of unseen blood in urine can come from a kidney infection, renal cell carcinoma, urinary tract obstruction, sickle cell anemia, renal papillary necrosis (a disorder of the kidneys).
Blood in urine causes also include different types of urological cancers, such as prostate cancer, kidney cancer and bladder cancer. An enlarged prostate can also cause blood in urine in men. When the prostate gland becomes enlarged, it constricts the urethra (the passageway through which urine flows). This can cause inflammation and irritation of the urethra and thus lead to urinary bleeding.
Other causes of blood in urine include bacteruria, or the presence of bacteria in the urine. Thin basement membrane disease, also known as benign familial hematuria, is a disease of the kidney that is characterized by microscopic hematuria, cloudy urine, or gross hematuria (visible blood in urine). This occurs because the basement membrane of the kidney’s capillaries (or vessels) becomes abnormally thin. It can cause blood in urine for children if the disease is inherited.
In certain instances you can expect microscopic hematuria. Urologic surgery such as enlarged prostate surgery, prostate cancer surgery, prostate cryosurgery, and prostate radiation commonly create microhematuria and gross hematuria for a short period. The same can be said for kidney surgery, bladder surgery, or penis surgery such as a penile prosthesis to overcome erectile dysfunction causes.
Microscopic hematuria is a sign that something is wrong and further tests should be done to determine the cause. If you are experiencing other symptoms with blood in urine, such as back or abdominal pain, frequent or painful urination, or urinary retention, your condition could be getting worse.
