Re: Partial Nephrectomy versus Radical Nephrectomy in Patients with Small Renal Tumors—Is There a Difference in Mortality and Cardiovascular Outcomes?

However, RN was not significantly renal disease was shown to significantly predict type ofthe PN group and 525 (21.6%) in the RN group. Of the 892 deaths, 173 were attributable to cardiovascular causes. In the PN and RN groups, 27 (4.9%) and 146 patients (6.0%), respectively, died of cardiovascular causes. When adjusting for preoperative demographic and comorbid variables, RN was associated with 1.4 times more cardiovascular eventsWords of Wisdo
