Retrospective study, from 1999 to 2010, including184 patients (median age 37 years) who underwent ventral onlay oral graft urethroplasty for bulbar strictures. Exclusion criteria were traumatic strictures, lichen sclerosus, failed hypospadias repair, failed urethroplasty, panurethral strictures, and incomplete medical charts. Pre-operative evaluation included clinical history, physical examination, urine culture, residual urine measurement, uroflowmetry, urethrography, ultrasound and urethroscopy. Surgery was considered a failure when any post-operative instrumentation was needed. Median follow-up was 48 months. Out of 184 patients, 38 (20.7%) had not undergone previous treatment, 7 (3.8%) had undergone dilation, 81 (44%) DVIU and 58 (31.5%) DVIU associated with dilation. Out of 184 patients, 157 (85.3%) were successful and 27 (14.7%) failures. Out of 38 patients who had not undergone previous treatment, 33 (86.8%) were successful;out of 7 patients who had undergone dilation, 6 (85.7%) were successful;out of 81 patients who had undergone DVIU, 72 (88.9%) were successful;out of 58 patients who had undergone DVIU and dilation, 46 (79.3%) were successful. According to the number of previous DVIU, ventral graft urethroplasty for bulbar strictures showed high failure rate in patients who had undergone more than four DVIU associated or not with dilation.展开更多
