find the incrising number of eosinophilic cell neoplasms (oxyphil adenoma) - oncocytoma.
Estimation of findings depicting kidney tumors and difficulties in early diagnosis were
Material and method. In Urology Clinic in Poznań during last 14 years (1982-
1995) 832 patients were operated due to renal tumors. In 12 (1.4%) oncocytomas were
found after patomorphological examination. Clinical symptoms, sise and localization of
the tumors in kidney and occurence according to the sex and age were described.
Comparison of the own and other results were carried out.
Conclusion. The best treatment in smali renal tumors should be a tumorectomy, but
diagnostic difficulties before surgical intervention are the reason why a radical
nephrectomy is prefered
