The results of internal urethrotomy with 6 weeks of postoperative catheter drainage and antimicrobial therapy in the treatment of urethral strictures in 28 patients are presented. Satisfactory results were obtained in 68 per cent of the patients. Because of the simplicity of this technique and the good results obtained we believe that internal urethrotomy often is the best initial approach to strictures that become difficult to manage by periodic dilation.
