What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compared two surgical methods for removing medium-sized bladder tumors (2-6 cm) in 50 patients. One method removes the tumor in one piece (en-bloc), while the other removes it in fragments (conventional). The goal was to see which method provides better tissue samples for diagnosis and potentially better outcomes.

What this could mean

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

What this could lead to
If en-bloc resection proves better, it could become the preferred surgical technique for removing medium-sized bladder tumors, improving diagnosis and reducing recurrence.
What could go wrong
This is a small, completed study with only 50 participants, so results may not apply to all patients. The comparison is about surgical technique, not a new treatment, so impact is limited.
