The Radiological Diagnosis of Neoplasms of the Urinary Tract: (Section of Radiology).
THE RESPONSIBILITIES OF THE RADIOLOGIST IN THE DIAGNOSIS OF URINARY TRACT NEOPLASMS ARE DISCUSSED: a strong plea is made for the routine use of pyelography in all cases in which renal tumour is suspected, and it is suggested that too much reliance is placed on the excretion method alone.FROM THE RADIOLOGICAL VIEWPOINT, RENAL TUMOURS MAY BE CONSIDERED IN THE FOLLOWING THREE GROUPS: (1) Parencymal tumours. (2) Tumours of renal pelvis. (3) Extrarenal tumours resembling renal tumours on clinical examination.The radiological signs which may be found in each group are described in detail, including the signs from plain radiography, instrumental pyelography, and excretion urography.The significance of non-excretion in small renal tumours receives attention. It is suggested that this is a sign of renal vein neoplastic thrombosis.The characteristics of osseous metastases from carcinoma of the kidney are considered with illustrative examples.Neoplasms of the ureter and their differential diagnosis are considered.
