NCT07668817

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in hemoglobin from baseline to PACU

    Change in Hemoglobin from preoperative baseline CBC to PACU CBC. A hemoglobin test measures the levels of hemoglobin in the blood. Hemoglobin is an iron-rich protein in the red blood cells. It carries oxygen from the lungs to the rest of the body. Cells need oxygen to grow, reproduce, and make energy to function. Hemoglobin levels provide information about the health of red blood cells.

    Baseline and Post-operative Day 0

Secondary Outcomes (4)

  • Change in Hemoglobin from baseline to Post-operative Day 10

    Baseline and Post-operative Day 10

  • Ureteroscopic tract bleeding score

    Post-operative Day 0

  • Proportion of participants undergoing stent placement

    Post-operative Day 0

  • Number of bleeding related events

    Post-operative Day 30

Study Arms (4)

Balloon Tamponade with no hemostatic agent

ACTIVE COMPARATOR

Balloon tamponade alone with no hemostatic agent acts as a control.

Interventions

FlosealDEVICE

Floseal is an active, flowable hemostatic matrix designed to stop surgical bleeding fast, usually within 2 minutes, by combining gelatin granules with human thrombin.

Balloon Tamponade with Floseal
SurgicelDEVICE

SURGICEL® (oxidized regenerated cellulose) is a plant-based, absorbable hemostatic fabric used to control capillary, venous, and small arterial bleeding.

Balloon Tamponade with Surgicel
SurgifloDEVICE

SURGIFLO® Hemostatic Matrix is an Ethicon porcine gelatin-based, flowable hemostatic agent used to stop bleeding during surgery, typically reaching hemostasis within seconds to minutes.

Balloon Tamponade with Surgiflo

Balloon tamponade is utilized to manage tract related bleeding.
