Tract Closure in PCNL

概要

This is a prospective, randomized controlled trial evaluating the effect of a hemostatic agent on tract-related bleeding during percutaneous nephrolithotomy (PCNL). Patients undergoing standardized PCNL will be randomized to receive either application of a hemostatic agent or no agent during tract closure, following uniform balloon occlusion, complete aspiration, and irrigation-free endoscopic assessment. The researchers hypothesize that adjunctive hemostatic agent use reduces perioperative hemoglobin decline compared with balloon tamponade alone and improves tract-related hemostasis outcomes.
