The authors present their own experience as well as data from the literature concerning the diagnosis and treatment of renal angiomyolipomas. In a group of 320 patients hospitalised at the Urological Clinic in 1990-1994 these tumours were diagnosed before surgery and confirmed by histological examination in 7 patients (2.2%). The group comprised three men and four women, mean age 51.7 years. Only one female patient had classical manifestations of tuberous sclerosis, the remaining patients did not have manifestations of tuberous sclerosis. Two patients were admitted with symptoms of haemorrhage into the retroperitoneum, three suffered from pain on pressure in the side and in two patients the tumour was revealed incidentally during US examination. Four patients were subjected to nephrectomy, in two enucleation of the tumour was performed and in one female patient with classical manifestations of tuberous sclerosis with a bilateral tumour conservative treatment was applied.
