Purpose A prospective study of partial vs. radical nephrectomy demonstrated worse overall survival in patients undergoing partial nephrectomy which appeared to be driven by cardiovascular outcomes. We sought to determine if the blood pressures or use of antihypertensive medications differed between patients who underwent partial or radical nephrectomy. Materials and methods A tertiary-referral institutional renal mass database was queried for patients between 2006 and 2012 undergoing partial or radical nephrectomy. Serial blood pressure follow-up, clinicopathologic variables, and changes in medications were collected. Patients were excluded for inadequate data, noncurative-intent surgery, noncancer surgical indication, and absence of medication information. Time-dependent hemodynamic changes were compared by split-plot analysis of variance and addition to antihypertensive regimen was studied as time-to-event survival analyses with Kaplan-Meier curves and a Cox proportional hazards model. Results A final cohort of 264 partial nephrectomy and 130 radical nephrectomy cases were identified. Patients undergoing partial nephrectomy were younger, more likely to have T1 tumors, and had lower preoperative creatinine (P<0.001 for all). No differences were noted on postoperative hemodynamics (P>0.05). Significantly more patients who underwent partial nephrectomy added antihypertensive medications postoperatively (P≤0.001) and surgical treatment remained as a significant independent predictor on Cox regression (hazard ratio = 2.51, P = 0.002). Limitations include the retrospective nature of the study and potential for unidentified confounders. Conclusion Hemodynamic parameters after radical or partial nephrectomy may be different. The etiology of this observation, is currently unexplored. Additional prospective mechanistic investigations are warranted.
