KIDNEY & URETER - Carcinoma of renal pelvis and ureter

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.
