Background: Percutaneous nephrolithotomy (PCNL) is accepted as the gold standard of care for the treatment of large renal calculi. Kidney hemorrhage, which requires blood transfusion, is one of the most common complications after percutaneous kidney stone surgery.
Objective: To evaluate perioperative factors associated with transfusion requirements during PCNL.
Materials and Methods: A total of 226 patients with kidney calculi undergoing PCNL between January 2011 and December 2019 were reviewed retrospectively. We analyzed the impact of perioperative clinical factors on the necessity of blood transfusion during PCNL.
Results: The overall blood transfusion rate was 9.29%. Multiple perioperative determinants were significantly correlated with the application of packed red blood cells (PRCs), including larger stone size (p = 0.006), multiple tract punctures (p = 0.029), presence of staghorn calculi (p = 0.026), and long operative time (OT; p = 0.017). Multivariate analysis demonstrated that only multiple tract punctures independently affected blood transfusion requirements during PCNL (p = 0.038).
Conclusion: In accordance with the present study, only the multiple tract punctures were associated with blood transfusion requirements in PCNL.
