[Treatment of urethral stenosis by self expandable endourethral prosthesis. Long-term results]

Urethral stenosis is a frequent disease in males. The variable results of its treatment have prompted the surgeon to search for new therapeutic alternatives. We propose to treat it by self expandable endourethral prosthesis.

Since February 1993 to March 2000 48 patients with urethral stenosis previously treated with endoscopic urethrotomy have undergone the procedure.

All patients completed a minimum of 3 years of follow-up. Patients lost to follow-up for any cause were not included in the final study description. All patients had satisfactory micturition at the time of discharge. Mean flow on uroflowmetry at three years was higher than 14 ml/ s in 87.5% (42/48 patients evaluated).

The use of self expandable endourethral prosthesis is a valid alternative in the treatment of recurrent urethral strictures due to its good long-term results and low morbidity. We recommend not using it in cases of traumatic etiology.
