Review of 8 patients with retroperitoneal fibrosis treated in our unit, 7 between 1985 and 1990 and one secondary to chronic use of non-steroidal anti-inflammatory agents diagnosed in 1980. In five patients no underlying reason was found and the remaining three were considered to be secondary (two to drugs and one to pelvic radiotherapy). Diagnostic and therapeutic approaches as well as patient's evolution are analyzed, also reviewing the existing literature.
Renal oncocytoma is an uncommon tumor. Of 223 renal tumors that were treated at our institution from 1970-1991, 14 (6.2%) were oncocytomas [9 females (65%) and 5 males (35%)]. The highest incidence was observed in the sixth decade (60.7 yrs). Tumor size range from 2 to 19 cm in diameter (mean = 8.07 cm); 11 (78.5%) were localized in the right kidney, principally in the superior pole. The tumor was incidentally discovered in 8 cases (57%); 1 case presented Wunderlich's syndrome; 1 had a palpable renal mass; 6 had abdominal pain. All the tumors were confined to the kidney. Thirteen were Robson stage I and 1 stage II. According to the UICC classification, 12 were T1, 1 T2 and 1 T3. All tumors were N0 M0. Patient evaluation included IVP (6), US (12), CT (14) and selective renal arteriography (2). The typical angiographic patterns were not observed in these 2 cases. Concerning the CT findings, in 8 cases (57%) the first diagnosis discarded was that of hypernephroma, although there were also signs suggestive of oncocytoma. Six cases (43%) showed signs indicating oncocytoma as first diagnosis. All patients were submitted to radical nephrectomy, which achieved good results in all cases at 7 months' to 5 years' follow up.
