|Anaesthetic Complication Neurological Central Nervous System Depression||Diagnostic Test: Change of Optic Nerve Sheath Diameter|
Advantages of using ultrasound in the assessment of intracranial pressure:
simple, bedside examination, repetitive, generally available, cheap, no exposure to X-rays, no need to transport the patient to the CT laboratory
Widening of the size of the optic nerve sheath outside of increased intracranial pressure may occur in the following pathologies:
optic neuritis optic nerve injuries meningioma of the optic nerve arachnoid cyst around the optic nerve tumors of the cavernous sinus Blood edema may occur due to impaired blood flow. The research is to determine whether the patient's position for urological procedures is safe for the patients and whether as a result of staying in such a position there is no development of cerebral edema.

change of the optic nerve sheath diameter
The test group will be male and female patients, aged over 18 and below 90 years of age. Each patient will be operated for urological reasons in the position for lithotomy.
Diagnostic Test: Change of Optic Nerve Sheath Diameter
In patients, the optic nerve sheath width (ONSD) examination will be performed twice: for the first time immediately after general anesthesia and again after surgery after placing the patient in a position on the back.
- Optic Nerve Sheath Diameter [ Time Frame: 10 hours ]
- neurological complications [ Time Frame: 5 days ]
