We compared postoperative renal function impairment between patients undergoing
robot-assisted partial nephrectomy (RAPN) and those undergoing open partial
nephrectomy (OPN) by using Tc-99m diethylenetriaminepentaacetic acid (DTPA) renal
scintigraphy. Patients who underwent partial nephrectomy by a single surgeon
between 2007 and 2013 were eligible and were matched by propensity score, based
on age, tumor size, exophytic properties of tumor, and location relative to the
polar lines. Of the 403 patients who underwent partial nephrectomy, 114 (28%)
underwent RAPN and 289 (72%) underwent OPN. Mean follow-up duration was 35.2
months. Following propensity matching, there were no significant differences
between the two groups in tumor exophytic properties (P = 0.818) or nephrometry
score (P = 0.527). Renal ischemic time (24.4 minutes vs. 17.8 minutes, P < 0.001)
was significantly longer in the RAPN group than in the OPN group, while the other
characteristics were similar. Multivariate analysis showed that greater
preoperative renal unit function (P = 0.011) and nephrometry score (P = 0.041)
were independently correlated with a reduction in glomerular filtration rate. The
operative method did not correlate with renal function impairment (P = 0.704).
Postoperative renal function impairment was similar between patients who
underwent OPN and those who underwent RAPN, despite RAPN having a longer ischemic
time.
