Materials and Methods
The Kidney Cancer Database of the Turkish Urooncology Association was
interrogated, and 3400 patients presenting between 2000 and 2018 were
retrospectively identified from the Redcap Database. Of those, 1004
patients with cT1N0M0 renal masses who underwent either PN or RN with
open and/or laparoscopic approaches were included in the study cohort.
Patients with a solitary kidney, a bilateral tumor, metastatic disease,
and/or a preoperative eGFR<15 ml/min/1.73 m2 were excluded.
All procedures were performed by eight experienced surgeons from six
different institutions. Patients were divided into two groups depending
on whether they underwent PN or RN. Demographic parameters, including
age; sex; the presence of diabetes, coronary artery disease, and
hypertension; and operative data including surgical approach, ischemia
type and time, histopathological evaluation, renal function assessments,
and complications were recorded and analyzed. The Institutional Review
Board of the University of Cukurova approved the study (52/March-2019).
