Cat’s urine is an indicator of disease

For pet doctors, cat’s urine is also an indicator of disease. The kidneys are part of the urinary organs, and we all know that the kidneys are the body’s is an important endocrine organ, so when a cat has endocrine abnormalities, it will show up through urine, and urine tests can help doctors diagnose the disease. Urine collection method for cat urine test, cat raising guide!

Urinary abnormalities in cats mainly include color abnormalities, and urinary disorders, such as polyuria, oliguria, dysuria, urinary incontinence, etc., with different clinical manifestations The location of the disease may be different. In addition to observing its color, the health of the cat must also be judged by the changes in the components of the urine. Before doing a urine test on the cat, we must first collect urine from the cat. Generally speaking, the cat’s There are several methods of urine collection:

1. Catheterization

Catheterization should be performed under aseptic conditions as much as possible. Catheterization can avoid most contaminants in the vagina, penile foreskin, and perineum, but it is possible that an unclean urethral opening can contaminate urine. During catheterization, bacteria introduced into the bladder may cause infection of the otherwise healthy lower urinary tract in dogs and cats. The risk of iatrogenic bacterial infection is greater in those cases with pre-existing urinary tract infection. Pushing the catheter too hard can cause the diseased urethra or bladder to rupture. Operational errors can also cause normal urethra and bladder rupture. During catheterization, the presence of a wound will increase red blood cells, proteins, and epithelial cells in the sample.

2. Bladder compression

In principle, bladder compression is not recommended for urine collection. If there is trauma to the urinary system, pressure on the bladder can increase red blood cells and protein in the urine sample. If the animal has urethral obstruction, recent major trauma to the bladder, or a cystotomy, compression of the bladder should not be used to collect urine. Excessive pressure can rupture the bladder, and it is more likely to rupture if the bladder itself is diseased. Forcibly compressing the bladder to collect urine will cause urine to flow back from the bladder back into the ureter, increasing the risk of infection. Contamination of the urethra, vagina, or penis and foreskin must be considered when evaluating urine collected by this method.

3. Natural urination

When using natural urination to collect urine, the middle section of urine is the best, because the initial urine flow will mechanically Wash out the dirt in the urethral opening and vagina or vaginal menstruation and foreskin. Urine samples collected from cages or the ground are inferior, but still very effective if contamination factors are taken into account. But when the contaminant is related to cells, proteins or bacteria, another urine collection method must be used to prove the abnormality in the urine sample. Natural urination is the urine collection method of choice when hematuria is affordable, because other methods will cause bleeding and increase the amount of red blood cells during urine collection.

4. Bladder puncture

Bladder puncture can avoid contamination of the urethral opening, vagina, penile foreskin and perineum by pollutants. Recently conductedThis method cannot be used for routine urine collection in patients with severe bladder incisions or severe bladder trauma. Cystocentesis can minimize non-urethral contamination of urine samples. It is mainly established that trauma caused by the pinhole may cause iatrogenic hematuria and urine from the bladder puncture site into the abdominal cavity.

Urine samples should be sent to the laboratory in containers that are safe and free of chemical contamination. The collected urine samples should be analyzed as soon as possible. If they cannot be analyzed within 30 minutes, they should be refrigerated.
