Emergent intervention criterias for controlling sever bleeding after percutaneous nephrolithotomy

Area of Science:

• Urology
• Nephrology
• Surgical Oncology

Background:

• Percutaneous nephrolithotomy (PCNL) is a common procedure for kidney stones.
• Post-operative bleeding is a potential complication of PCNL.
• Identifying predictors for severe bleeding is crucial for patient management.

Purpose of the Study:

• To determine the criteria for emergent intervention in patients experiencing bleeding after PCNL.
• To analyze the characteristics and outcomes of patients requiring emergent surgery for severe bleeding post-PCNL.

Main Methods:

• Retrospective analysis of 850 patients who underwent PCNL.
• Monitoring of urine output, blood pressure, and hemoglobin levels post-surgery.
• Identification of patients with severe bleeding requiring emergent intervention.

Main Results:

• 60 patients (7%) required blood transfusion post-PCNL.
• Five patients (0.6%) experienced severe bleeding necessitating emergent surgery.
• Severe bleeding cases presented with metabolic acidosis, anuria/oliguria, and significant hemoglobin drop.
• One patient died due to massive bleeding and cardiopulmonary arrest; others were managed with open surgery or transfusion.

Conclusions:

• Severe bleeding post-PCNL is a rare but life-threatening complication.
• Metabolic acidosis and anuria/oliguria in conjunction with falling hemoglobin levels are indicators for emergent surgical intervention.
• Prompt intervention is vital to prevent potentially fatal vascular collapse.
