ABSTRACT
BACKGROUND:
Hypertension (HTN) is a global public health issue. There are limited data regarding the effects of HTN in patients undergoing partial nephrectomy (PN) for renal tumors. To address this void, we tested the association between HTN and renal function after minimally invasive PN (MIPN).METHODS:
Using a multi-institutional database (2007-2017), we identified patients aged ≥ 18 years with a diagnosis of cT1 renal tumors treated with MIPN. Kaplan-Meier plots and Cox regression models addressed newly-onset CKD stage ≥ 3b or higher (sCKD). All analyses were repeated after 11 propensity score matching (PSM).RESULTS:
Overall, 2144 patients were identified. Of those, 35% (n = 759) were yes-HTN. Yes-HTN patients were older, more frequently male and more often presented with diabetes. Yes-HTN patients harbored higher RENAL nephrometry scores and higher cT stages than no-HTN patients. Conversely, yes-HTN patients exhibited lower preoperative eGFRs. In the overall cohort, five-year sCKD-free survival was 86% vs. 94% for yes-HTN vs. no-HTN, which translated into a multivariable HR of 1.67 (95% CI 1.06-2.63, p = 0.026). After 11 PSM, virtually the same results were observed (HR 1.86, 95% CI 1.07-3.23, p = 0.027).CONCLUSIONS:
Yes-HTN patients exhibited worse renal function after MIPN when compared to their no-HTN counterparts. However, these observations need to be further tested in a prospective cohort study.
