Read the detailed description
Type of study: prospective study
Review of literature:
- Different modalities of urethroplasty for correction of CPCC without hypospadias (Nesbit, modified Nesbit, dorsal dartos flap, combined plication-incision CPI, suture fixation to pubic bone).
- Merits of modified Nesbit technique accompanied by dorsal dartos flap for one-stage correction of CPCC without hypospadias.
This is a prospective study conducted at pediatric surgery department, New Damietta \& Alhoussain Al-Azhar University Hospitals, from January 2015 to May 2020, on 56 male patients with isolated CPCC. All of them will undergo one-stage correction corporoplasty using modified Nesbit technique accompanied by dorsal dartos flap.
Institutes of the study:
A multicenter study at Pediatric Surgery Departments, Al-Azhar University hospitals at New Damietta \& Cairo. Number of cases: Fifty-six male patients. Time frame: period of 5.6 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 study protocol was approved by local research and ethics committee of Al-Azhar Faculty of Medicine; the study protocol was explained to all guardians and their informed consents were obtained for involvement in the study. Confidentiality and the right to withdraw from the study at any time were guaranteed.
Preoperative preparation:
Children with CPCC those fulfill inclusion criteria will undergo a nursing evaluation of functional health status and a preoperative evaluation by an anesthesiologist \& pediatrician. The angle of penile rotation will be measured on the photograph, using Millen Med DICOM viewer program for image analysis, based on the orientation of the urethral meatus relative to the vertical position.
Follow-up:
Patients will be followed-up at OPD.
Statistical Analysis:
Data will be summarized into continuous variables expressed as mean ± standard deviation and categorical variables expressed as frequency count and percentage (%), using appropriate software computer package. Fisher's exact test is used for comparison of frequency counts/percentage. A two-sided p-value < 0.05 is considered statistically significant.
Discussion:
It will focus on one-stage correction of congenital penile curvature complex (CPCC) using modified Nesbit's procedure (to correct curvature) and dorsal dartos flap (to correct torsion). 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 noticing urine stream direction. At the end, the investigators will conclude that this technique ensures correction of the complex penile anomaly with satisfactory results and nice cosmetic outcome.

Questions about this trial
What is this clinical trial studying?
A study testing Modified Nesbit's procedure and dorsal dartos flap in people with Congenital Anomaly and Chordee, run by dr. Muhammad Abdelhafez Mahmoud, MD at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Clockwise rotation (time frame: 5 years). The study lists 9 primary outcomes in all. 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 19 Nov 2020; AzTrials last refreshed its copy on 7 Nov 2026.
