[Tumors of the upper urinary tract].

A series of 60 cases of tumours of the Upper Urinary Tract (UUT) diagnosed in our centre between 1987-1996 and affecting 57 patients is presented. Patient's mean age was 63.7 years, males being clearly predominant, 4:1, there was no predominant laterality and the preferential location was the renal pelvis. Fifty-two (52) out of all tumours were transitional, 1 was a fibroepithelial polyp and 2 were metastasis from prostate and colon cancers. Pathoanatomy of the remaining cases is not known since no surgery was performed, although the cytologic diagnosis has identified them as transitional tumours. Our series shows a significant association to other transitional tumours as demonstrated by the existence of 2 cases with a background of UUT tumours and other 31 cases associated to transitional tumour of the bladder. Haematuria was the predominant sign (54%) and UIV the leading examination technique. Nephroureterectomy was the most commonly used therapeutical approach. UUT appear to be highly predominant in our environment, with a clear male predominance and preferential location in the renal pelvis. Haematuria continues to be the most frequent presentation sign and UIV the exploratory technique offering better performance in the diagnosis. Also a high association was found to other types of transitional tumours, the diagnosis and follow up of which allowed us to diagnose a large number of tumours of the upper tract.
