[Tuboscopy--an endoscopic approach to the intratubal lumen].

A linear everting catheter in combination with a 0.5-mm microendoscope enables the visualization of the tubal lumen. In 35 sterility patients, diagnostic tuboscopies were performed. Physiological and pathological results of tubal mucosa are described. Tuboscopy is a main tool in the diagnosis of the tubal factor. First steps are taken to use tuboscopy not only for diagnostic but also for therapeutic reasons. Yet, the role of this technique in cases of tubal pregnancies cannot be evaluated.
