Kidney and ureter, opened to display finely papillary lesion in the pelvis and upper ureter, with discrete
pelvic deposits. There is marked dilatation of the calyces, many of which contain blood clot, and some
seem to contain haemorrhagic tumour.
This man had developed severe left-sided pain, radiating round the abdomen and suggestive
of renal colic. A retrograde pyelogram showed several filling defects in the left ureter, as well as a
ragged appearance to the pelvis of the kidney, suggesting a pelvic tumour. The histology of the lesion
is that of a well-differentiated papillary transitional cell carcinoma. Seedlings of tumour were found in
the ureter, right down to the lower end. Eighteen months later he presented with urinary retention
and investigation showed a bladder neck tumour; no pathological report of this lesion could be found.
