Do you know how many kidneys a person should have under normal circumstances? The answer is: 2.
The kidneys are one of the few organs in the human body that grow in pairs. The two kidneys jointly undertake the function of excreting excess water and metabolites in the human body and producing a variety of essential hormones for the human body.
However, some people, for various reasons, only have one kidney, which is often called “solitary kidney”. The causes of solitary kidney can be divided into two categories.
One type is congenital due to renal dysplasia since embryonic period, causing one side of the kidney to be missing; the other type is due to malignant tumor,Severe hydronephrosis, kidneySerious infection, traumaFor other reasons, one kidney was surgically removed,for acquired nature。
Most patients with congenital solitary kidney have no obvious symptoms. During the physical examination, patients often find that “Huh? I have one less kidney than others!” The more common solitary kidney caused by surgical resection, patients often have different degrees of foundation. Diseases, such as kidney cancer, kidney stones, severe hydronephrosis, renal tuberculosis, etc.
The function of the kidney is very powerful. Whether it is a congenital or acquired solitary kidney, when the human body has only one kidney, the solitary kidney, the size of the kidney will be slightly larger than that of a normal person. We call it “compensatory enlargement”.
The only remaining kidney needs to meet the physiological metabolic needs and has to undertake double the work.
Compared to people with two normal kidneys:
(1) With the increase of age, the renal function decline of the isolated kidney population appears earlier, faster and more obvious.
(2) Solitary kidney is more sensitive to renal injury caused by drugs and ischemia.
(3) When a solitary kidney patient suffers from chronic diseases such as hypertension, diabetes, hyperuricemia/gout, and autoimmune diseases at the same time, because these are high-risk factors for kidney disease, renal dysfunction or even uremia occurs. more likely.
It is worth noting that in patients with chronic kidney disease before unilateral nephrectomy, the remaining solitary kidney after surgery may experience rapid decline in renal function, or even progress to the uremic stage in a short period of time, requiring renal replacement therapy. possible. Therefore, it is very important to protect the function of the solitary kidney and prevent and control the progression of chronic kidney disease.Cyrus Daily Tablets|where to buy sialis|Where to buy Cialis 5mg|Cialis 5mg|Cialis 5mg daily tablet| Cialis 5mg 28 price
