Abstract

La présente invention concerne un cystoscope portable consistant en un dispositif manuel portable peu coûteux permettant à un médecin de pouvoir introduire une partie télescopique optique (12) du dispositif manuel dans l'urètre (110) d'un patient de manière à placer une lentille optique (16) à l'intérieur de la vessie (112) afin de visualiser l'écoulement depuis les orifices urétraux jusque dans la vessie. La perméabilité peut être confirmée par visualisation du colorant indigo provenant de chacun des orifices urétraux dans la vessie au moyen du cystoscope portable. Lorsque c'est confirmé, une image visuelle fixe ou animée peut être enregistrée au moyen du cystoscope à main décrit dans cette invention. Dans un mode de réalisation associé, une heure et une date peuvent être enregistrées ainsi que les informations relatives à la perméabilité après une intervention chirurgicale.
