Can you know if your kidneys are good or not just by urinating? What is the healthiest amount of urine? tell you the answer
live forever
Probably can't escape the topic of shit and fart
Always feel indecent but can't help but pay attention
But it is undeniable
Shit, piss and fart science is a serious science
It is worth studying carefully
Take advantage of this lunch time
Today we're going to have a light meal
one release of pee
Requires kidneys, ureters, bladder, urethra
4 departments work together
Urinary Department - Kidney
The kidneys are a pair of lentil-shaped organs
The basic duty is to produce urine
The kidneys have about a million "nephrons"
(aggregates of glomeruli, tubules, etc.)
And it is in these units that urine is born
in daily life
You can pass 2 indicators
to roughly assess kidney function
One is the amount of urine
Normal urine output is 1000-2000 ml/day
Too much or too little urine
may be due to poor kidneys
Be especially careful with nocturnal urination
The second is the level of creatinine in the blood
eGFR on medical checklist
(Glomerular Filtration Estimate)
Visual assessment of renal function
Transmission tube - ureter
The total length of the ureter is 20-30 cm
Divided into upper, middle and lower sections
Every paragraph has a "life and death knot"
And these three
It is the place where the ureter is most prone to damage and lesions.
Among them, stones are the most common
The peak age of onset in men is 35 years
There are two peaks for women: 30 and 55
Patients typically experience intermittent low back cramps
Symptoms such as hematuria, frequent urination, urgency, and dysuria
want to avoid getting sick
Drink more water, exercise more, and avoid obesity is the best way
Reservoir - Bladder
well known
The bladder is a flexible organ
When lying in bed and holding back urine in winter
When playing games and watching movies
It's all about the bladder carrying the weight behind the back
long term
Urinary tract infection and cystitis
even bladder cancer
Outlet - urethra
urine formed by the kidneys
through the ureter to the bladder
Finally pass the last level - the urethra
excreted
However, the length of the urethra differs greatly between men and women.
Men are about 16~20cm
Women are 3~4cm
And the urinary tract has 3 big nemesis
drinking less water, holding back urine, sedentary
Together they can cause urinary tract infections
Mildly poor urination, severe nephritis
even sepsis
Therefore, for urinary tract safety
One more thing to add
That is to have regular checkups
Adult men and women should have a physical examination once a year
Urine routine and urinary system B-ultrasound are mandatory
