XXXX is a factor to consider before performing a partial nephrectomy.

@entity5 @entity1358
BACKGROUND: We conducted a retrospective analysis of radical nephrectomies performed in our clinic in order to evaluate the incidence of multifocality in relation to the stage, grade, size and histological type. MATERIALS AND METHODS: Preoperative imaging studies and the final pathological results of surgical specimens were reviewed. Separate @entity5 at a distance of more than one cm from the @entity5 were counted. Of 56 @entity1358 10 (17.8%) were multifocal. Of these 10, 3 were found with @entity5 less than or equal to 4 cm, while 7 were found with @entity5 between 4-10 cm. Three multiflocal @entity5 were found with TI @entity5 , none with T2, 4 with T3a and three with T3b @entity5 . Six cases were present where the histological subtype of the @entity5 was clear cell, while 4 had mixed cell histology. No multifocality was observed in the 4 grade I @entity5 , while 3 of the 32 grade II @entity5 and 6 of the 20 grade III @entity5 were multifocal. The only grade IV @entity5 presented with a separate @entity5 . Statistically significant correlation was found between multifocality and @entity5 grade stage and clear cell histology subtype. There was no correlation between the @entity5 size and the possibility of multifocality. CONCLUSION: Although partial nephrectomies are justified from their survival rates, close follow-up is necessary because separate @entity5 may still exist in the kidney, left behind, irrespective of @entity5 size.
