Introduction
The detection of early-stage localized T1 renal tumors has increased due to the widespread use of modern imaging procedures. This has led to higher utilization of partial nephrectomy (PN), although radical nephrectomy (RN) remains the most commonly performed procedure for the excision of renal tumors (1,2).
According to the recent American and European guidelines, PN has become the standard treatment modality for T1 renal masses, and compared with RN, PN yields similar oncological results, superior preservation of renal function and minimization of the long-term risks associated with renal insufficiency when it is technically feasible (3-5). Despite these advantages, PN is technically challenging and carries a higher risk of perioperative complications than RN; thus, RN is still chosen for some patients (6-8). However, it is essential to preserve long-term function to avoid chronic kidney disease (CKD), which may be associated with adverse events such as the development of cardiovascular disease. Currently, few studies have reported the prediction of short-term postoperative renal function, and the results of these studies were inconsistent in terms of the preservation of renal function after PN and RN (9-15). More recently, researchers have attempted to identify which patients will benefit more from PN, which may help clinicians select the appropriate surgery.16 Preserving renal function (RF) depends on factors such as the preoperative parenchymal quality, the volume of the preserved parenchyma, and ischemia time and type (10).
In this study, long-term renal function and patient and surgeon parameters significantly affecting the outcomes of PN and RN were investigated using the kidney cancer database of the Turkish Urooncology Society.
