Kim JH, et al. - Researchers investigate the annual trend of prevalence of benign pathologic findings after partial nephrectomy (PNx). Further, they determined the factors that can be associated with this prevalence. They performed a cohort study of 18,060 patients between 2007 and 2014, indicating the overall prevalence of benign pathologic findings after partial nephrectomy of 30.9%. Female sex, old age, and performance of computed tomographic imaging only as preoperative imaging modality were identified to influence the prevalence. Outcomes thus suggest a high prevalence of benign pathologic findings after partial nephrectomy. Clinicians are advised to focus more on possible risk factors, especially radiologic modalities to avoid unnecessary surgeries for renal mass.
