Hysteroscopic cannulation

Hysteroscopic cannulation is a procedure done to remove blocks in the tubes in inner end of the tube, where it opens into the uterus.
In case of blocks in the tubal opening into the uterus, a cannula is passed into the opening to remove the block after viewing it through the hysteroscope. In infertile patients, hysteroscopic cannulation is often combined with laparoscopy.
