Metastatic involvement of the ureter due to renal parenchyma neoplasia has been reported in a total of 53 cases in the literature, the described mechanisms for tumoral spread being: haematogenic, lymphatic, canalicular and direct. Time to appearance of metastasis is far from prompting agreement among the authors in terms of its synchronous or metachronous nature. The most frequently reported symptoms are total and painless haematuria, and obstructive uropathy: CAT, percutaneous nephrostomy (for locally advanced disease) and endoscopy, are the most frequently used diagnostic tools. The only available therapy is nephrouretectomy for a diagnosis synchronous with the primitive tumour, and uretectomy for metachronous emergence. This paper reports on a case of sarcomatoid renal tumour with ipsilateral synchronous involvement of the ureter, which caused an obstructive uropathy treated by nephrouretectomy.

Polycystic disease of the adult is the most common presentation of renal cystic disease and is transmitted by dominant autosomic heredity. Development of renal cell carcinoma has been reported within this cystic disease, but the frequency of such coincidence is not higher than in the remaining population. Most of these tumours are found incidentally and may involve a diagnostic problem due to the marked distortion of the kidney's architecture produced by the polycystic disease of the adult.

The authors present the case of a three-year old girl in whose left kidney, they observed a cystic image communicating with a calyx. The authors class the said lesion as a simple, renal cyst open to ducts. They make a differential diagnosis with other entities (calicial diverticulum, hydrocalicosis, hydatidic cyst and kidney tumour) on the basis of histological, radiological and clinical findings. To reach the same, they assess the structure of the cyst epithelium which is at all times simple cuboid; the radiographic image and the intravenous urography by filling the cyst cavity retrogressively with contrast and the record of macroscopic hematuria which would correspond to the rupture of the cyst in the excretory duct. The suggest a traumatic origin in the mechanism which opened the cyst into the excretory duct.
