Study summary

Hypospadias is an anomaly characterized by an ectopic ventral urethral meatus, and an incomplete or hooded prepuce. Its incidence is estimated at 1 in 200-300 live male births, with variations across populations and severity types.

Successful hypospadias repair depends largely on optimal tissue healing and robust vascular support around the neourethra. Thus, many adjunctive techniques have been investigated to improve outcomes, including dartos flaps, tunica vaginalis flaps, and various tissue sealants.

In recent years, attention has turned toward biological augmentation strategies, particularly the use of platelet-rich plasma (PRP) and platelet-rich fibrin as a potential enhancer of wound healing.

Platelet-rich fibrin (PRF), a second-generation autologous platelet concentrate, has recently emerged as another promising biologic in tissue engineering.

This study aims to evaluate the effect of PRF application in primary hypospadias repair surgery and determine its effect in improving healing and reduction of postoperative complications.

Read the detailed description

All patients included in the study will undergo primary hypospadias repair using the standardized Tubularized Incised Plate (TIP) urethroplasty technique (Snodgrassi procedure), under general anesthesia and by the same surgical team to minimize variability

  • Steps of the Surgical Procedure (Same for Both Groups):

    1. Preoperative preparation:

  • IV antibiotics, sterile field setup, general anesthesia. 2. Urethral plate incision and tubularization over a 6-8 Fr stent using absorbable sutures.

    3. application of PRF (Group A only):

  • 8-10 mL of autologous blood is drawn into plain (non-anticoagulant) tubes according to the patient's weight and the size of the patch needed.
  • The sample is immediately centrifuged using the single-spin method (typically 3,000 rpm (400x g) for 12 minutes).
  • This produces three layers:

    • Top layer: acellular plasma (PPP)
    • Middle layer: platelet-rich fibrin (PRF) clot
    • Bottom layer: red blood cells The PRF clot is gently removed and compressed using a gauze to form a thin PRF membrane.
  • PRF membrane is fixed on top of the suture line as a first layer and under the incision line as a second layer and secured using a few resorbable polyglyconate 6/0 interrupted sutures.

    4. Glansplasty and skin closure using standard techniques in both groups 5. Catheter and dressing:

  • A soft catheter is left in place for 5-7 days.
  • A mild compression dressing is applied.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2026; primary completion for Aug 2027, 12 months later.

Of 60 non-industry interventional studies with no phase under Hypospadias, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 39. This study's planned 12 months is below that.

Counting every sponsor, half of 60 studies reached it within 15 months; a quarter within 8 and three quarters within 39.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
