Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial compares two ways of finishing kidney stone removal surgery. In one, a medical glue called Glubran 2 is sprayed into the access tract to seal it, avoiding the need for a drainage tube. In the other, a standard tube is placed. The study aims to see if the glue technique reduces pain, bleeding, and hospital stay while still clearing the stones effectively.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Nebulized Glubran 2 (a medical glue) used to seal the access tract after kidney stone removal
What this could lead to
If it works, this technique could make kidney stone surgery less painful and shorten hospital stays by avoiding a drainage tube.
What could go wrong
This is a small, early-stage trial, and the glue might not seal as well as expected, leading to complications like urine leakage or bleeding.
