Summary

This study looks at whether adding a small drainage tube in the belly during surgery for large bladder stones (over 2 cm) can make the operation faster and easier. About 140 adults will be randomly assigned to get the standard procedure alone or with the extra tube. The main goal is to see if the tube shortens surgery time and improves visibility for the surgeon.
