PURPOSE: To examine the mode of relapse detection and subsequent treatment after partial or radical nephrectomy in @entity1 with low-risk ( @entity2558 , N0, Nx) @entity703 . METHODS: Retrospective study on 1404 @entity1 treated with partial or radical nephrectomy for @entity703 from the years 2000-2012. Scans for chest imaging (X-ray or CT) and abdominal imaging (CT, MRI, or ultrasound) are tabulated. For those @entity1 with relapse, the site, mode of detection, and symptoms were recorded. RESULTS: Twenty-one @entity1 relapsed with a median follow-up of 4.1  years for @entity1 who did not relapse. In 17 (81  %) @entity1 , relapse was detected by imaging alone, while 4 (19  %) @entity1 presented with symptoms. Of the @entity1 who relapsed by imaging, 13 (76  %) were treated immediately, while 4 (24  %) continued observation. During the first 3  years of follow-up, 5762 imaging studies were performed to detect 8 relapses, with 6 @entity1 receiving immediate treatment. The median number of imaging studies per @entity1 per year for the first 3  years was 1.7 (interquartile range 1.0, 2.3) including 30  % CT, 3  % MRI, 36  % X-ray, and 31  % ultrasounds. CONCLUSION: We found a low yield of surveillance imaging in the first 3  years for @entity2558 @entity703 . Nearly 1000 imaging studies were performed to detect one relapse that required treatment. Further studies are needed to evaluate the clinical impact of imaging surveillance according to recent guidelines.
