Reply to Wei Qi's letter to the editor about "Preoperative proteinuria correlates with renal function after partial nephrectomy for renal cell carcinoma".

In this Letter, we respond to Wei Qi's Letter to the editor regarding our paper, "Preoperative proteinuria correlates with renal function after partial nephrectomy for renal cell carcinoma" (World Journal of Urology, 2024), addressing the concerns raised with the aim of clarifying the potential benefits of our findings in clinical practice.

Preoperative proteinuria correlates with renal function after partial nephrectomy for renal cell carcinoma.

Purpose: Preoperative proteinuria is a prognostic factor of chronic kidney disease (CKD). We assessed the association between preoperative proteinuria and postoperative renal function after partial nephrectomy (PN).

Methods: We retrospectively reviewed our records of patients with a single malignant renal mass who underwent PN between 2000 and 2021.
