Urine Testing (Urinalysis)

Urinalysis is quite often prescribed by doctors when a patient complains of pain in the pelvic area, back pain or difficulty in urination. The reason for such pains could be anything like BHP, prostate cancer or just a urinary infection. One of the reasons for the recommendation of this test is to find out the exact cause of the symptoms and also to diagnose the problem. This is a diagnostic technique that most of the doctors use along in conjunction with other tests like DRE or PSA tests. 

Prostate cancer is one of the common types of cancer found in men above the age of 50. This disease needs an early detection to increase the chance of cure or survival. Prostate cancer refers to the presence of cancerous cells in the prostate glands. If the patient feels pain in the pelvic area and frequent urination then detailed analysis of urine is recommended by the doctor. In fact, urinalysis is one of the first tests suggested by doctors to detect prostate problems.   

What Is Urinalysis? 

Urinalysis is the test conducted on the patient’s urine sample suffering from symptoms like pain in the pelvic area, blood in urine, pain while urinating, frequent urination, and abdominal pain. In case the test results show increased levels of glucose, red blood cells or protein, then further evaluation is performed to determine the exact problem. In case of early stages of prostate cancer, urine samples may not reveal anything to confirm the presence of malignancy. As a result, the urologist will use this test in conjunction with other tests.  

Urinalysis Procedure 

When a patient visits the doctor for pain in the pelvic area, he may be prescribed urine testing (urinalysis) in a credible lab. The patient must visit the lab early in the morning to give the urine samples. Usually, the first urine of the day is collected as sample. The sample is then put in a machine and mixed well until the sediments settle down. The sediments are then placed under the low-powered microscope to study about its casts, cells, crystals, etc. Then the same sample is placed under high-powered microscope to study the presence of bacteria, debris or casts etc. Considering the test results the doctors decide about further evaluation and diagnosis.  

Interpretation of Urinalysis  

There are several interpretations of urinalysis. While a normal urinalysis may not guarantee perfect health of the subject, sometimes early stages of prostate cancer may not get reflected in the test.  

Visual Examination: Any disparity in the visual results of urinalysis can be an indication of disease or problem in patient’s urinary system. 

Chemical Examination: The chemical results of urinalysis gauge urine samples for - specific gravity, protein, pH, ketones, glucose, leukocyte esterase, urobilinogen and bilirubin. 

Microscopic Examination: When visual and chemical examinations of Urinalysis do not show satisfactory results, a microscopic examination is usually performed. This examination is conducted on urine that has been concentrate after centrifuging.  

Considering the complexity and the significance of Urinalysis, it should be conducted only in certified laboratories under expert guidance.
