[Urethral stenosis: presuppositions on the physiopathology and our experience with internal urethrotomy].

From 1982 till 1986 in our department 92 patients with single or multiple urethral strictures underwent internal urethrotomy according to Sachse. The Authors present a critical evaluation of etiology, pathophysiology, clinical-prognostic factors and therapeutic methodology. The results confirm the efficacy of internal urethrotomy in both the primary and relapsing urethral strictures.
