ClinConnect Summary

This clinical trial is studying a new way to perform a kidney stone surgery called total tubeless percutaneous nephrolithotomy (PCNL). Unlike traditional methods, this surgery does not use tubes that are usually placed in the kidney to help with drainage. This modified approach aims to make the surgery less painful, quicker, and more cost-effective. The trial will explore performing the surgery without first inserting a catheter through the urethra, which has been linked to complications in the past.

To be eligible for this trial, participants must be between 6 months to 80 years old and have kidney stones that are less than 35 mm in size. They should also have no serious infections or significant health issues that would make surgery risky. If you decide to participate, you can expect to undergo the surgery in a comfortable position, and the study aims to ensure a safer experience with fewer complications. Your participation can help researchers better understand this new surgical method and its benefits for patients with kidney stones.
