Mean age of the patients was 51.3±12.7years. Mean perirenal fat
dissection time was 15.0±13.5min. Patient demographics, BMI, nor
occupational status differed between the 3 complexity of perirenal fat
dissection groups. Radiological findings showed that there was a
significant correlation between perirenal fat depth and complexity of
perirenal fat dissection(p<0.05), but not with HU measurements
or subcutaneous fat thickness. Surgeon classification of the complexity
of perirenal fat dissection was in accordance with the duration of
dissection(p<0.05). Perinephric fat contained more fibrous
tissue in the patients with histologically proven APF than in those
without(p<0.05).
