Transitional cell carcinoma of the kidney.

This paper presents 14 personal patients with transitional cell carcinoma of the kidney who were managed over a period of 13 years. Emphasis is placed on the diagnostic features, the great variety of radiological appearances of this neoplasm and the value of preoperative cytological examination of urine. In three patients the tumour started in the mucosa of peripheral calyces, and did not involve the surgical renal pelvis; this added to the diagnostic difficulty, and led to delay in diagnosis and treatment in one patient. The possibility that this tumour may be more common in Australia because of the high incidence of analgesic nephropathy is raised.
