We report on a woman, her mother and her mother's cousin who had papillary transitional cell carcinoma of the ureter associated with other cancers of the genitourinary tract. Neoplasms in these family members may be due to interactions between host susceptibility factors and exposure to environmental carcinogens. Studies of peripheral blood karyotype and urine mutagenic activity yielded normal results.

Nephrectomy is a radical operation successfully used over more than a century. It should be resorted to only in exceptional situations whenever an organ salvaging operation is precarious for the patient's health (T Patrashkov, 1980). The indications for nephrectomy depend on the type of disease, extent of renal damage, state of the second kidney and the patient's general condition, established by the basic examination methods in urology (T Patrashkov 1982). The study covers 388 nephrectomies in cases presenting diverse diseases of the kidney and ureter, diagnosed and treated in the Department of Urology--University Hospital "Alexandrovska" in the period 1990 to 1995. The commonest causes leading to nephrectomy comprise: 1. Neoplasms of kidney and ureter--134 (34.54%). 1.1. Parenchymal tumors--116 (29.90%)/ 1.2. Papillary tumors--18 (4.64%). 2. Pyonephrosis--88 (22.68%). 3. Nephrolithiasis (presence of renal calculi)--53 (13.66%). 4. Secondary operations of the kidney and ureter--46 (11.86%). 5. Hydronephrosis--38 (9.80%). 6. Anomalies (hypoplasia)--8 (2.06%). 7. Cystic diseases--7 (1.80%). 8. Tuberculosis of kidney--6 (1.55%). 9. Renovasal hypertension--4 (1.02%). 10. Nephrectomy for other diseases--4 (1.02%). As shown by the results the rate of nephrectomy undertaken for renal malignancy is still the highest which is by no means considered as a favourable diagnostic sign.

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.
