Factors Predicting Urethral Stricture Recurrence After Dorsal Onlay

Status Completed

Clinical Trial Summary

In this observational study, the investigators will evaluate potential risk factors associated with urethral stricture recurrence after augmentation anterior urethroplasty using dorsal onlay buccal mucosal Graft during the past 10 years. Patients' medical files will be reviewed for data relevant to demographics, clinical and operative characteristics. data will be analyzed using the appropriate statistical tests and the independent predictors of urethroplasty outcome will be identified.

Clinical Trial Description

In this series, the investigators will study different factors related to the stricture and to the patients to identify the independent predictors of urethral stricture recurrence after augmentation anterior urethroplasty using dorsal onlay buccal mucosal graft. A retrospective review of medical records will be performed to identify patients who underwent augmented anastomotic anterior urethroplasty with dorsal onlay graft at Al-Azhar University Hospitals in Egypt since 2010. Patients will be included only if they were two or more years out of surgery. The data will be recorded without patients' identification. Data to be collected are patient age, body mass index (BMI), smoking status, diabetes status, overall comorbidity, stricture etiology, prior endoscopic treatment and open urethroplasty, urethral stricture length and location, degree of urethral obliteration, urethral plate width, presence and degree of spongiofibrosis. estimated intraoperative blood loss, catheter size, overall operative time, hospital stay and early postoperative complications. The diagnosis of urethral stricture recurrence is based on the radiological and endoscopic features of stricture recurrence. Time to recurrence will be calculated from the date of surgery till the date restricture diagnosis. Univariate and multivariate regression analysis will be performed and factors predicting urethral stricture recurrence will be identified. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
