Specific features of blood supply and topography of the ureters in patients with nephroptosis, multiple arteries of the kidneys and ureteral duplication were established on the material of 42 preparations of the kidneys and ureters taken from corpses of people who died at the age from 20 to 78 years. Standard anatomical methods were used. It was shown that in people with nephroptosis at the sites of the approach of the upper ureter vessels, of cross of the ureters and the testicular (ovarian) and iliac vessels there are points of fixation around which the ureters undergo greatest deformities and might be responsible for disturbances of the urine outflow. The ureteral vessels are often involved in adhesions in the sites of deformities of the ureters. In cases with a duplication of the renal arteries as a rule have their beginning from the renal artery located below (72,2i%). With a greater distance between the beginning of the doubled renal arteries the upper ureteral arteries on one side, the lower artery of the kidney is located atypically (behind the inferior vena cava) and is not a source of blood supply of the ureter. In cases with a partial duplication (split) of the ureters in the abdominal part they are supplied with blood from the common source. |
