Decreased Urination
Alternate Names : Oliguria, Decreased Urine Production
How is the condition diagnosed?
Diagnosis begins with a medical history and physical exam. This may be all that is needed to figure out the cause. In other cases, further testing is needed. Different tests may be ordered, depending on the suspected cause.
Blood and urine tests are commonly ordered. Sometimes, the urine is collected over a 24-hour period to get an exact measurement of the amount of urine being made. Special X-ray tests of the kidneys and bladder may also be done.
In some cases, a procedure called a kidney biopsy is needed. A special needle is inserted through the skin and into one of the kidneys. A small piece of the kidney is then removed with the needle. The piece is sent to the lab for examination to help figure out the problem.
