Culture - urine - catheterized specimen; Urine culture - catheterization; Catheterized urine specimen cultureDefinition Return to top
Catheterized urine specimen culture is a procedure to obtain a urine sample through a catheter (a thin rubber tube) inserted through the urethra into the bladder. The urine is obtained by this method to avoid contamination from the urethra, or if urine cannot be collected by the clean catch method.How the test is performed Return to top
Adults and children:How to prepare for the test Return to top
Do not urinate for at least an hour before the test. If there is no urge to urinate, you may be instructed to drink a glass of water 15 to 20 minutes before the test may be requested. Otherwise, there is no preparation for the test.How the test will feel Return to top
There is some discomfort. As the catheter is inserted, there may be a sensation of pressure. If a urinary tract infection is present, there may be a painful sensation when the catheter is inserted due to inflammation of the urethra.Why the test is performed Return to top
The test is performed to obtain a sterile urine specimen in a person who cannot voluntarily urinate, when an infection is suspected in the urinary tract, or when urinary retention is suspected. Tests for organisms that cause infection are performed after the urine is collected. This can also help monitor ongoing infections.Normal Values Return to top
Normal values depend on the test being performed. Normal results are reported as "no growth" and indicate an absence of infection.What abnormal results mean Return to top
A "positive" test indicates enough organisms detected to cause urinary tract infection.What the risks are Return to top
There is a slight risk of perforation (hole) from the catheter and a risk of infection.Special considerations Return to top
Rarely, a suprapubic aspirate may be performed if a sample cannot be obtained by other methods. In this method, a needle is inserted through the skin of the lower abdomen into the bladder to withdraw urine.
