Abstract: years of follow up imaging.We collected and analyzed multiple variables.Radiology reports were reviewed from follow up imaging and were categorized as 'normal' or 'abnormal.'RESULTS: 180 patient charts were reviewed.127 (70.5%) were considered to have normal findings on initial imaging, and 53 (29.5%) with abnormal findings.There was no significant difference between groups regarding gender, age, tobacco status, race, length of stay, or BMI.We compared mass size of normal and abnormal groups which was approaching significance with median values of 2.5 and 2.8, respectively.Median time to initial follow up imaging for normal vs abnormal was 205 vs 133 days, respectively (p¼ 0.02).On subsequent imaging 60% of abnormal studies were downgraded to normal.The median time interval between the first and second imaging study for normal vs abnormal was 188 vs 157 days (p¼<0.01).There were 4 patients with initial abnormal imaging and 5 patients with initial normal imaging found to have recurrent or metastatic disease, but only 1 in each group within a year from surgery.CONCLUSIONS: Post-operative imaging within 160 days after partial nephrectomy more often returned abnormal results compared to patients with initial imaging on average 205 days after surgery.This resulted in more frequent follow up of patients with an abnormal initial image.60% of abnormal imaging became normal on subsequent imaging.2/180 patients were found to have a suspicious nodule concerning for metastatic disease within 1 year of their original surgery.Based on our results, we believe post-operative surveillance with CT or MRI after partial nephrectomy should not be obtained until 1 year after surgery.
