[Triple tumor pathology of the left urinary tract]

The authors present one case of three coexisting tumours in one excretory duct. The absence of clear haematuria at any time and the radiolucid urographic image, along with the clear picture of left, reno-ureteral colic, led to their considering the wrong diagnosis of left ureteral lithiasis. They discuss the rarity of the presence of three tumours, according to the world statistics, and the importance of the ascending pyelography and the exfoliative cytology for the diagnosis of suspicious radiotransparent images of the ureter.
