Reply to Lorenzo Marconi, Karim Bensalah, and Axel Bex`s Letter to the Editor re: Paul C.M.S. Verhagen, Egbert R. Boevé. The European Association of Urology Guideline on Renal Cell Carcinoma (RCC) is Not Concise in its Recommendation to Perform Partial Nephrectomy in T1b RCC. Eur Urol. In press. https://doi.org/10.1016/j.eururo.2019.01.020 (European Urology)

We appreciate the opportunity to respond to the comments by Marconi et al., who suggest that we propose to change the guideline on renal cell carcinoma (RCC) on the basis of a single patient experience; however, this is not what we have argued [1]. The case was presented as a reason to review the evidence underlying the recommendations of the guideline. We came to the conclusion that to date there is not a single study to substantiate the recommendation in the current European Association of Urology guideline on RCC to perform partial nephrectomy in T1b RCC.
