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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at whether 3D models of the kidney can help predict if all kidney stones will be removed during surgery. Researchers analyzed 105 patients who had kidney stone surgery and used CT scans to create 3D images. They found that certain features of the kidney's shape and stone location could help predict whether any stones would be left behind. The goal is to help surgeons plan better and improve 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 successful, this could help surgeons plan kidney stone removal more accurately, reducing the chance of leftover stones.
What could go wrong
This is a small, retrospective study, not a treatment trial. The model needs validation in larger, prospective studies before it can be used in practice.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: ① preoperative diagnosis of renal calculi confirmed by computed tomography urography (CTU); ② completion of standard-channel (F24) PCNL with the puncture and target calyces situated in different renal calyces; and ③ postoperative CT imaging performed within one week after surgery. Exclusion Criteria: ① anatomical abnormalities of the affected kidney, such as severe renal rotation or horseshoe kidney; and ② history of secondary procedures, including repeat PCNL or renal puncture with fistula formation.
