Disturbances of urinary flow result in an increase in intrapelvis pressure and a decrease in the kidneys ability to filter urine. The impairment of the blood flow in renal parenchyma represents one of the causative factors. Compensatory mechanisms in case of prolonged occlusion include collecting system dilation as well as pyelorenalis reflux. These changes lead to urine circulation via glomerular and tubular apparatuses, the interstitial tissue and lymphatic vessels and lead to the pyelovenous reflux. The results of studies dedicated to impairment of blood flow in the kidney parenchyma during the ureteral occlusion and in different types of the surgical treatment of urolithiasis are presented in the article.
