Results: Using this method, three cases of renal tumors, six cases of nephroptosis, three cases of renal artery stenosis, three cases of renal atrophy due to chronic pyelonephritis, and five cases of unstable bladder were checked out. The causes of eight cases of urinary obstruction were identified.
