summary

Obstructive nephropathy in the elderly is very common in clinic. Obstructive nephropathy refers to the disease of renal function and substantial damage caused by urinary flow disorder. The disease can be acute or chronic. The lesion is usually unilateral, but many cases can be bilateral. How is senile obstructive nephropathy caused? Let's talk about it

How is senile obstructive nephropathy caused?

There are many causes of obstructive nephropathy in the elderly, and there are many ways to classify it. At present, most scholars advocate to classify it according to the etiology, that is, according to the etiology of obstruction site, it can be divided into intracavitary, intramural and extramural. According to different causes, the lesions can be unilateral or bilateral.

Any cause of obstructive nephropathy in the elderly can lead to structural and functional lesions of obstructive kidney; When the obstruction was relieved, the glomerular filtration rate (GRF) could return to 2 / 3 of that before obstruction; If the obstruction was relieved after 4 weeks, GRF could only recover to 20% - 25% of the original level; If the complete obstruction is more than 4-6 weeks, it will cause irreversible damage of renal structure and function.

After urinary tract obstruction, urine continues to produce, which makes the pressure in urinary system continue to increase and the proximal urinary tract dilate. When the pressure in the urinary system approaches the glomerular filtration pressure (0.8-1.6kpa), the glomerular filtration rate becomes lower and lower. In the early stage, the balance of internal environment can be maintained through a series of compensatory mechanisms.
