Tubeless percutaneous nephrolithotomy without retrograde ureteral catheterization for the treatment of pediatric upper ureteral stones: One case report.

Introduction: Traditional Percutaneous Nephrolithotomy (PCNL) typically involves the retrograde placement of a ureteral catheter. However, this procedure can present additional risks in pediatric patients.

Case Presentation: We report a case of a 10-year-old boy, weighing 33 kg, diagnosed with a right upper ureteral stone complicated by hydronephrosis and urosepsis.

Clinical Discussion: Tubeless PCNL without retrograde indwelling ureteral catheter was performed on the second day of hospitalization.

Conclusion: This case applied tubeless PCNL without retrograde ureteral catheterization in a single prone position. The procedure was successful and safe.
