Laparoscopic ureterolysis for ureteral stenosis led to a rare complication: pneumothorax. This occurred due to carbon dioxide (CO2) diffusion through congenital diaphragmatic defects, necessitating conversion to open surgery.

Area of Science:

  • Urology
  • Anesthesiology
  • Thoracic Surgery

Background:

  • Retroperitoneal fibrosis can cause ureteral stenosis, requiring surgical intervention.
  • Laparoscopic ureterolysis is a minimally invasive approach for treating ureteral obstruction.
  • Carbon dioxide (CO2) insufflation is standard for laparoscopic procedures, creating a pneumoperitoneum.

Observation:

  • A 71-year-old female developed right pneumothorax during laparoscopic ureterolysis for left ureteral stenosis.
  • Intraoperative findings included increased peak airway pressure, elevated PaCO2, and subcutaneous emphysema.
  • Breath sounds over the right lung became absent, indicative of lung collapse.

Findings:

  • The pneumothorax was attributed to CO2 diffusion from the peritoneal cavity to the pleural space.

  • Congenital defects in the diaphragm were suspected as the pathway for CO2 migration.
  • Resolution of pneumothorax and subcutaneous emphysema occurred after peritoneal gas evacuation.

    • Implications:

    • This case highlights a rare but serious complication of laparoscopic surgery involving CO2 insufflation.
    • Diaphragmatic integrity should be considered in patients undergoing laparoscopic procedures, especially with risk factors.
    • Recognition and prompt management of CO2-induced pneumothorax are crucial for patient safety.
