Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Review of literature:
* Different modalities of urethroplasty for repair of proximal hypospadias with chordee (two-stage repair, one-stage repair, flap, graft).
* Disadvantages of two-stage urethroplasty for proximal hypospadias with chordee..
* Merits of one-stage urethroplasty for proximal hypospadias with chordee. This is a prospective randomized controlled study conducted at pediatric surgery department, Al-Houssain \& New Damietta Al-Azhar University Hospitals, from March 2014 to March 2020, on 144 male patients with penoscrotal hypospadias with chordee. Patients will be investigated by routine laboratory tests for fitness for surgery. All of them will undergo one-stage repair using either of 2 techniques of tubularized preputial flap; Duckett's versus DFPF. Written informed consent will be obtained from parents of all participants in the study.
Institutes of the study:
A multicenter study at Pediatric Surgery Departments, Al-Azhar University hospitals in Cairo and New Damietta. Number of cases: One-hundred-Forty four male patients. Time frame: period of 6 years.
Ethical Consideration:
The protocol will be discussed and approved for clinical study by the Ethical Research Committee at the principal investigator's hospital. The procedures and the aim of the study will be clearly explained to the patient and the family. A written informed consent will be obtained before enrollment of the patients into the study. The family refusal to give consent for one-stage repair is respected but does not deprive the patient from getting surgical care by two-stage repair.
Preoperative preparation:
All patients will be subjected to history taking, clinical examination, and necessary laboratory investigations (CBC, Coagulation profile, Liver and Renal Function tests, Electrolytes Panel, Urinalysis). They will receive a dose of single broad-spectrum antibiotic 30 min-1 hour before surgery. Patients will be randomly divided (using the computer-generated randomization table) into two equal groups, each will include 72 patients; Group I will undergo transverse preputial island flap (Duckett's technique) and Group II will undergo double-faced preputial flap (DFPF). Both techniques will be done by all members of the surgical team equally.
Follow-up:
Patients will be followed-up at OPD.
Statistical Analysis:
Data were collected using a data collecting sheets (annexes) and were analyzed using the statistical package for social sciences (SPSS) version 24.0 (IBM SPSS Statistics for Windows, IBM Corp, Armonk, NY, USA). Continuous variables were expressed as mean±standard deviation (SD), range, and average and categorical variables were expressed as frequency count \& percentage. Fisher's exact test was used for comparison of frequency counts/percentage. A two-sided p-value \< 0.05 was considered statistically significant.
Discussion:
It will focus on one-stage urethroplasty using the preputial flap for proximal hypospadias with chordee. The results obtained from this study will be compared between both group and with those reported in the literature.
Also, it will focus on results, complications, their management, and clinical evaluation by estimated urine caliber and micturition time. At the end, the investigators will conclude the reconstructive technique that gives the better results and least morbidity.
