[Clinical relevance of proximal tubal occlusion--diagnosis and therapy].

Clinical examination of potential tubal disease is an essential part of the investigation of infertility. Proximal tubal occlusion accounts for 10-25% of tubal factor infertility. Authors review the history, methods and value of the relevant diagnostic and therapeutic procedures of proximal tubal occlusion, as well as determine the exact role of hysteroscopic selective tubal cannulation in the work-up process. Upon the relevant literature and the authors' data, the mentioned procedure is recommended in the assessment of the infertile females in order to avoid unnecessary in vitro fertilization procedures.
