Urine test is also a "big difference between men and women"!
Almost everyone has had a urine test, and most people will emphasize "middle urine" when taking urine, but few people know "why". Du, a urologist at Shu Tian Clinic, said, "The so-called middle urine can actually be called' bladder urine', which is still stored in the bladder before urination, so we can see whether there are any bacterial residues in the bladder and what diseases there are, and at the same time we can summarize the health conditions above the bladder, including ureters and kidneys. 」
Du said that women are more likely to get cystitis, so when taking urine, most of them take middle urine. "Moreover, the urine in front will have the problem of external pollution. Urine may be contaminated by external bacteria and the test will be inaccurate. But for boys, men are more prone to urethritis, so sometimes they will take the urine in front to see the inflammation and infection of the urethra. " So there are still some differences between boys and girls. 」
The urine output at one time is about 250, and the former 10 is the former urine, and the latter 10 is the latter urine, most of which are taken during examination.
But sometimes, in order to check whether there is chronic prostatitis, men will take urine from the posterior segment for examination. As before, they will pass the anterior and middle urine first, and then the doctor will help the patient finish the prostate. Part of the secretion will flow out from the urethra, called EPS, and the last urine will be called "posterior segment urine". If the number of white blood cells in EPS is significantly higher than that in the front and middle urine, it means chronic prostatitis.
What's the difference between peeing for the first time in the morning and not peeing for the first time?
Du Yuan Bo said that the first urine in the morning is stored in the bladder for the longest time. If there are lesions, the specimens are also the longest and most preserved, such as proteinuria and hematuria. Seeing the first urine is the most accurate. "The amount is the most, and it is thicker, and it is better to cultivate and observe. 」
However, for people who have frequent urination and nocturnal urination habits, the first time to urinate in the morning is not long enough, and the effect is not good. Du said, "So men like old people usually have nocturia. At this time, we will take the longest interval, usually at noon. 」
