[Post-traumatic stenosis of the membranous urethra]

Secondary urethral stricture is the most serious complication of traumatic rupture of the membranous urethra, directly related to the treatment of the rupture. In a series of 45 patients treated for urethral rupture with a minimal follow-up of 5 years, 30 developed stricture (66%). An urethral guide, inserted in 31 cases, was responsible for the stricture in 26 of these cases (84%). This stricture developed rapidly (average of 7.4 months), whether the initial rupture was complete or incomplete and was longer (average of 35 mm) in the case of complete rupture. End-to-end urethrorraphy performed between the 15th and 35th day in 14 patients was complicated by 4 secondary strictures (28%). The treatment of the stricture depended on the initial treatment of the rupture and the radiological length of the stricture. In the case of stricture secondary to an urethral guide, end-to-end urethrorraphy for a stricture less than or equal to 40 mm (12 cases) and 2 stage urethroplasty for a stricture greater than 40 mm (4 cases) achieved a good result in 68.8% of cases. The strictures secondary to end-to-end urethrorraphy (4 cases) were treated by direct vision urethrotomy (3 cases) with 100% of immediate good results and by urethral telescoping (1 case) complicated stress urinary incontinence.
