Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Objective: To explore the risk factors and treatment outcomes of contralateral new upper tract urothelial carcinoma (UTUC) after nephroureterectomy in a large single-center cohort of UTUC patients. Methods: A retrospective analysis of the clinicopathological data of 509 consecutive patients treated by nephroureterectomy from 2000 to 2010 at a high-volume center in China was conducted. Results: Thirty-five patients (6.9 %) were found to develop contralateral UTUC. Gross hematuria was a common symptom, and aristolochic acid (AA) containing Chinese herbs was identified as an underlying cause. In multivariate analysis, renal transplant recipients (HR = 16.507) and preoperative renal insufficiency (HR = 2.523) were independent risk factors. No correlation was found in the clinical and pathological characteristics of primary and subsequent contralateral UTUC. A second round of nephroureterectomy should be performed on renal transplant patients, whereas patients who are older, exhibit relatively better renal function, and have tumors that are single, located in the ureter and small size could be treated with nephron-sparing surgery. No survival difference was detected between the two treatment groups, and developing contralateral UTUC was not associated with worse survival. Conclusion: Contralateral UTUC is comparatively rare, and gross hematuria is a common symptom. Renal transplant history and renal insufficiency are independent risk factors, and prophylactic contralateral nephroureterectomy is considered for uremic UTUC patients with proper renal replacement treatment or renal transplant recipients. These features are likely related to the mechanisms of multifocality of UTUC, and the potential correlation with AA remains to be elucidated. Tumor characteristics and renal function are informative for the decisions concerning surgical options for contralateral UTUC. © 2014 Springer-Verlag Berlin Heidelberg.
