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 study compared two ways to remove kidney stones that are 2-3 cm in size. One method uses a laser and a special suction tube through a scope in the urinary tract. The other is a mini-surgery that makes a small cut in the back. Researchers looked at how well each method cleared the stones, how much bleeding occurred, and any complications. The goal is to find which approach is safer and more effective for patients.

What this could mean

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

Active substance
High-power Holmium:YAG laser with flexible navigable suction access sheath
What this could lead to
If successful, this could show that the newer laser procedure is as effective as or better than the standard mini-surgery for removing medium-sized kidney stones, with fewer complications.
What could go wrong
This is a small, completed study with only 60 participants, so results may not apply to everyone. Both procedures carry risks like bleeding or infection.
