The paper presents the results of surgical treatment of @entity5 of the kidneys. @entity5 were detected in 28 of 1200 @entity1 with @entity1358 (2.3%). @entity5 were found in 12 @entity1 (42.8%), asynchronous--in 16 (57.2%). Operation on both the kidneys for @entity5 was carried out in 21 @entity1 from 28 (75%). In both groups operations including enucleation of the @entity5 (60% in the group with @entity5 and 53.8%) in the group with asynchronous one) prevailed. All the @entity1 were operated in two stages. Local relapses occurred in 6 of 21 @entity1 (28.5%). A relapse after nephrectomy was observed in 2 @entity1 (9.5%). Recurrent @entity5 in the remnant of the kidney after nephron-sparing surgery was observed in 4 @entity1 (19%). General 5 year survival in @entity1 with @entity5 was 38.5%, whereas 5-year cancer-specific survival reached 47.4%. For @entity5 these parameters were 49.6 and 58.7%, respectively. It is emphasized that all @entity1 with @entity703 after radical nephrectomy should be followed up and undergo annual check-up with US and/or CT lifelong to detect possible @entity5 . Genetic studies are necessary to specify differentiation of the form of bilateral @entity5 .
