Factors Predicting Urethral Stricture Recurrence After Dorsal Onlay Augmented, Buccal Mucosal Graft Urethroplasty

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
