ClinConnect Summary

This clinical trial is studying a type of surgery called tubeless percutaneous nephrolithotomy (PCNL), which is used to remove kidney stones. This new approach does not involve placing a ureteral catheter, which is a small tube typically used in traditional procedures. Researchers want to find out if this method is safe and effective, as it may lead to less discomfort after surgery, shorter hospital stays, and lower costs.

To participate in the trial, you need to be between the ages of 18 and 75, have a kidney stone that is less than 3.5 centimeters in size, and agree to undergo this tubeless surgery. However, if you have certain health issues, such as severe heart or lung problems, or if you have had previous kidney stone surgeries, you may not be eligible. If you join the study, you can expect to receive care from a medical team that is monitoring your progress and ensuring your safety throughout the process.
