Angiography and microangiography were carried out on 38 kidneys: 21 by operation, 17 in necropsy, and their findings were examined in connection with the histological findings.
After the irrigation by saline with heparin, barium sulfate was injected under the pressure of 150mmHg and radiogram was taken.
The sample for histological examination was taken from the kidney after angiography.
The findings of radiography were evaluated based on the abnormal findings such as stenosis, irregular lining, circular running, abnormal distribution and reduced branches in interlobar artery, arcuate artery, and interlobular artery.
1) In acute pyelonephritis, there were slight abnormal findings.
2) In chronic pyelonephritis, there were considerable differences among the cases.
3) In hydronephrosis, there were moderate changes in their vascular system.
4) In hydronephrosis complicated with chronic pyelonephritis, severe changes were revealed.
5) In most cases of renal tuberculosis, there were rather severe changes.
6) The special findings in microangiography such as stenosis, circular running, irregular lining of the arteries seemed to suggest the degree of the histological changes.
