kateterinäyte

Kateterinäyte refers to a sample of urine collected using a urinary catheter. This method is employed when a clean catch urine sample cannot be obtained, such as in patients who are unable to voluntarily void or when a sterile urine sample is required for diagnostic purposes.

The procedure involves inserting a sterile catheter into the bladder through the urethra. Once the catheter is in place, a small amount of urine is drained and collected into a sterile container. Strict aseptic technique is crucial during catheterization to minimize the risk of introducing bacteria into the urinary tract, which can lead to a catheter-associated urinary tract infection (CAUTI).

Kateterinäytteet are commonly used to diagnose urinary tract infections, assess kidney function, and monitor the effectiveness of antibiotic treatment. The collected urine is typically sent to a laboratory for analysis, which may include urinalysis and urine culture and sensitivity testing.

While effective for obtaining urine samples in certain clinical situations, the use of urinary catheters carries potential risks, including infection, trauma to the urethra, and bladder spasms. Therefore, catheterization is generally performed only when necessary and for the shortest possible duration. Alternative methods for urine collection are preferred when feasible.
