What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

When a kidney stone blocks urine flow and causes a dangerous infection called urosepsis, doctors must drain the kidney right away. They can use a stent placed through the urinary tract or a tube inserted through the skin. This study compares how each drainage method affects the later surgery to remove the stone, tracking stone-free rates, operation time, blood loss, complications, and hospital stay in 100 adults.

What this could mean

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

Active substance
emergency urinary drainage by ureteral stent or percutaneous nephrostomy tube, followed by kidney stone removal surgery
What this could lead to
If one drainage method clearly leads to better stone removal results, doctors could adopt it as the standard first step for patients with infected, blocked kidneys.
What could go wrong
This is a single-center study of 100 people, so its results may not apply everywhere. Both drainage methods carry risks of bleeding, infection, or tube problems, and the comparison may show little difference between them.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 100 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

Jun 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

Show the full entry requirements

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

Inclusion Criteria: * Age 18 years or older. * Presence of renal or proximal ureteral stones. * Presentation with urosepsis secondary to obstructive urolithiasis. * Emergency urinary decompression performed by either retrograde ureteral stent (Double-J stent) or percutaneous nephrostomy (PCN). * Patients scheduled for definitive stone management via percutaneous nephrolithotomy (PCNL) after clinical stabilization and infection resolution. * Written informed consent obtained prior to enrollment. Exclusion Criteria: * Congenital renal anomalies (e.g., horseshoe kidney, ectopic kidney). * Pregnancy. * Uncorrectable coagulopathy or bleeding disorders. * Active, uncontrolled urinary tract infection at the time of definitive PCNL. * Severe cardiopulmonary comorbidities rendering the patient unfit for surgery or general anesthesia. * Patients managed definitively by other modalities (e.g., ureteroscopy or ESWL alone).
