[20 years urethroplasty experience. Retrospective review and outcomes.]

To present the evolution in the diagnosis and treatment of urethral stricture, after performing 300 surgical procedures over urethral meatus,penile and bulbar urethra along 20 years, contrasting two surgical periods: from 1997-2006 to 2007-2016. MATERIAL AND METHODS: A retrospective review of495 medical records between 1997-2016 was conducted.All the patients treated with urethroplasty were included and those who under went internal urethrotomy,stents or dilatations plus those with strictures due to prostate cancer treatment or orthotopic neobladder were excluded. RESULTS: 300 patients were selected: 100 patients within the first period (1997-2006) and 200 within the second (2007-2016). The median follow-up was 36 months (range 12-60). In relation to the surgical techniques, among the most employed, four are outstanding so their results can be compared in both periods:termino-terminal urethroplasty, penile flap urethroplasty and the buccal mucosa in penile or bulbar urethroplasty.Other techniques were incorporated during the second period. The best outcomes were provided by end' to endurethroplasty with 90 and 92% success. Over the second period, buccal mucosa indications were consolidated with an increase use from 16% to 56%. Were considered as successful those patients that did not need any endoscopic procedure and reporting excellent urinary flow without low urinary tract symptoms. CONCLUSIONS: A trend towards an increased usage of open surgery vs urethrotomy is observed. Buccal mucosa graft has been consolidated as a reconstructive technique. End-to end urethroplasty seems to provide the best functional outcomes.
