Two distinction fluids are used in operative hysteroscopy. One is monopolar and the second is bipolar. The monopolar fluid contains mannitol and the bipolar fluid contains serum physiologic. This study aims to compare intracranial pressure in patients undergoing monopolar and bipolar hysteroscopy.
Operative hysteroscopy is currently used in the treatment of several diseases including submucosal myomas, polyps, uterine septum, and abnormal intrauterine bleeding. Two different methods for distension of the uterus for hysteroscopy are available currently. One is monopolar and the second is bipolar. The monopolar fluid contains mannitol and the bipolar fluid contains serum physiologic. Passage of the distention fluid into the uterine veins during hysteroscopy might lead to volume overload, water intoxication, hyponatremia, pulmonary edema or brain edema. However, the effect of monopolar hysteroscopy or bipolar hysteroscopy on intracranial pressure in patients undergoing hysteroscopy is unknown. Optic nerve sheath diameter (ONSD) measurement is a surrogate marker of invasive intracranial pressure. This study aims to compare the impact of monopolar and bipolar hysteroscopy on intracranial pressure by using ONSD measurement in patients undergoing hysteroscopy.

Intracranial pressure
The difference in intracranial pressure between the two study arms measured with optic nerve sheath diameter (ONSD). ONSD is measured using a linear ultrasound probe and reflects intracranial pressure.
Time frame: ONSD will be measured 3 times in the two groups. Before completion of hysteroscopy, 2 hours after hysteroscopy and 6 hours after hysteroscopy
