Factors Predicting Urethral Stricture Recurrence After Dorsal Onlay Augmented, Buccal Mucosal Graft Urethroplasty
Factors Predicting Urethral Stricture Recurrence After Dorsal Onlay Augmented, Buccal Mucosal Graft Urethroplasty
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.
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.
Inclusion Criteria:

 -  patients who will be 2 years or more out of surgery

 Exclusion Criteria:

 -  patients with incomplete medical records or follow-up informations
