Introduction: Percutaneous nephrolithotomy (PCNL) is a common procedure for kidney stone removal, involving a small incision in the back and insertion of a nephroscope to extract the stones. Recent advancements include super-mini PCNL, employing smaller instruments for less invasive access to the kidney. However, conventional PCNL often requires tract dilation, which can lead to potential complications., Case Presentation: This case report presents the successful application of our surgical technique using the basic principles of PCNL with the aid of a pediatric trocar cystostomy and ultrasound guidance as a new alternative for super-mini PCNL, offering safer access with reduced bleeding risk and shorter recovery. The surgery was performed on a 55-year-old female with bilateral kidney stones, with the stone in the left kidney being larger than the one in the right kidney. The procedure was completed within 60 min without significant postoperative complications., Discussion: Our new alternative for PCNL offers benefits such as reduced invasiveness, shorter recovery time, decreased risk of complications, and minimal changes in postoperative hemoglobin levels. This new alternative can be performed in developing country hospitals that do not have the expensive PCNL equipment., Conclusion: This new alternative of PCNL with pediatric trocar cystostomy proves to be effective and safe., Competing Interests: Conflict of interest statement The authors declare that they have no competing interests., (Copyright © 2024 The Author(s).
