Background/Aim:
Whether anesthesia can affect oncological outcomes in urothelial carcinoma of the upper urinary tract undergoing radical nephroureterectomy (RNU) is not clear.
Patients And Methods:
One-hundred an ninety-seven patients who underwent RNU were retrospectively recruited and divided into total intravenous (TIVA, n=90) and volatile inhalation anesthesia (VIA, n=107) groups. A 1:1 propensity score-matching method was employed to minimize selection bias (n=70 each). Cancer-specific (CSS), overall (OS) and metastasis-free (MFS) survival were compared between groups before and after matching.
Results:
For all survival endpoints, no significant differences were observed between the two study groups, both before (hazard ratio for TIVA: CSS: 0.70, OS: 0.75, MFS: 0.78) and after (hazard ratios for TIV: CSS: 1.21, OS: 0.82, MFS: 0.84) matching.
Conclusion:
With no survival difference observed according to anesthetic technique for RNU, the choice should be based on factors such as accessibility, prevention of side-effects, or costs.
