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.

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.

Summary

This study compares two surgical techniques for correcting a common birth defect in boys where the urine opening is on the underside of the penis. One method uses a graft from tissue, while the other uses a special membrane made from the patient's own blood (platelet-rich fibrin) to help healing. The goal is to see which approach leads to fewer complications like fistulas or narrowing of the opening. The trial will involve 100 boys aged 6 months to 7 years.

What this could mean

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

Active substance
autologous platelet-rich fibrin membrane
What this could lead to
If it works, this could offer a safer, more effective surgical technique for boys with hypospadias, reducing the need for follow-up procedures.
What could go wrong
This is a relatively small, early-stage trial (100 participants) comparing two surgical methods. The benefit of platelet-rich fibrin is not yet proven, and surgical outcomes can vary widely.
