What is Hysteroscopic Cannulation?
Tubal cannulation is a procedure to open up tubal corneal blocks (origin of fallopian tubes near the uterus). It is done under hysteroscopic guidance (a procedure that allows the Gynaecologist to see inside the womb by means of a fine telescope called Hysteroscope, introduced through the neck of the womb) .
What Happens During Tubal Cannulation
Your doctor inserts a tube through your vagina called a catheter, which is guided over a wire. Either ultrasound or real-time moving X-rays of the fallopian tubes may be used to help your doctor find the correct spot. They open up the blocked area using a balloon on the catheter or with the wire.
Tubal cannulation may be done immediately after you have a procedure called hysterosalpingography In this, your doctor flushes dye through the catheter to identify and locate a fallopian tube blockage.
You may or may not get anesthesia during the procedure. Your doctor might give you a mild sedative to help you relax.
