Penile HypospadiasNCT06808139
Pearls and Pitfalls in Usage of Plasma-Rich Platelet Graft Versus Dartos Flap in Distal Penile Hypospadias Repair
A study testing Plasma-Rich Platelet Graft and Dartos Flap in people with Penile Hypospadias, run by Assiut University.
Trial summary
Hypospadias is the most common congenital anomaly of penis. It is the second most common genital birth defect in boys after cryptorchidism The reinforcement of hypospadias repair with an intermediate layer is believed to reduce the incidence of postoperative complications such as uretherocautanous fistula.

About this study
Hypospadias is the most common congenital anomaly of penis. It is the second most common genital birth defect in boys after cryptorchidism The reinforcement of hypospadias repair with an intermediate layer is believed to reduce the incidence of postoperative complications such as uretherocautanous fistula.
Hypospadias is classified by the location of the abnormal urethral meatus into distal penile (glandular ,subcoronal and distal penile), mid penile and proximal penile hypospadias Indeed, uretherocautanous fistula is most common complication after urethroplasty, with introduction of a protective layer between the neourethra and the covering skin strongly reduces fistulas occurrence and the overall complication the aim of the study To evaluate and to compare the use of PRP covering layer and dartos fascia flap layer in regard to complication rates in hypospadias repair

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Plasma-Rich Platelet GraftProcedure or surgery
The clot was extracted from the tube, separated from red blood cells, and gently compressed between two surgical swabs to obtain a soft and resistant membrane. The Snodgrass technique was carried out for all patients, with a suitable size catheter (8-12-Fr), repair was carried out by a continuous layer of polyglycolic suture (Vicryl) size 6/0, covered by an interrupted second layer. In group A, after finishing the Snodgrass TIPU, a PRP sheet coverage was applied over urethroplasty and secured by Vicryl 7/0, and finally the skin sutured directly without any covering layers
Dartos FlapProcedure or surgery
preputial dartos flap will be used
| Study group | Role | What they receive |
|---|---|---|
| Group A | Active comparator | Plasma-Rich Platelet Graft Receives: Procedure: Plasma-Rich Platelet Graft |
| Group B | Active comparator | Dartos Flap Receives: Procedure: Dartos Flap |
What is being measured
The primary outcome is the main question the study is designed to answer.
incidence of occurrence of uretherocutanous fistula
occurrence of conection between urthera and skin
Measured: 6 month

What does the primary outcome measure?
incidence of occurrence of uretherocutanous fistula (time frame: 6 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Feb 2025.
