Between April 1980 and December 1999, 23 kidneys in 20 @entity1 were diagnosed as having @entity8 at our institution. The @entity1 were 6 males and 14 females aged 24 to 79 years, with a mean age of 55.4 years. Two @entity1 had associated @entity2916 and 3 had bilateral disease. Of all @entity1 the main clinical symptoms were @entity158 (45%) and palpable mass (40%); 5 @entity1 (25%) had asymptomatic lesions. The size of the @entity5 ranged from 1.3 to 24 cm (mean 7.7 cm). Treatment consisted of nephrectomy in 9 @entity1 , partial nephrectomy in 6 and selective embolization in one. Pre-operative diagnosis was @entity1358 in 5 of the 9 @entity1 who underwent nephrectomy. Six @entity1 with 7 diseased kidneys were followed radiologically. One @entity1 underwent percutaneous biopsy to confirm the diagnosis. We suggest that nephron-sparing surgery for @entity1 with @entity8 should be the first step if @entity5 size is 4 cm < or = or increasing rapidly. Selective embolization is also a useful method. However, we need long-term follow-up to evaluate the effectiveness of embolization.
