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.
