Clinical Trial Summary

In this study, in patients with benign prostatic hypertrophy, monopolar and transurethral prostate using bipolar techniques in resection; serum electrolytes in the perioperative period, osmolarity can occur in hemodynamic parameters the effect of changes on optic nerve diameter by ultrasonography.

Description:

This study is for TURP operation for Benign Prostate Hypertrophy patients. When patient comes to the operating room, routine preparations will be made. Haemodynamic parameters and over-the-eye with Optic nerve diameter will be checked with ultrasound before and 10 minutes after spinal anesthesia. Monopolar for patients according to the preference of the surgical team resectoscope technique or bipolar resectoscope technique will be applied. During the operation Blood pressure, pulse minute the number of irrigation solutions used and the amount of intravenously administered serum, operation time will be saved. Optic nerve sheath diameter after the operation would be checked again. intraoperative and postoperative complications in the waking room (respiratory distress, hypotension, hypertension, bradycardia, tachycardia, vomiting, headache, restlessness, seizure, arrhythmia, vision disorder) will be recorded.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	optic nerve sheath diameter(mm)	A linear 10-5 MHz ultrasound probe (GE Healthcare Logiqe Series) was held on the upper eyelid over the gel carefully. Part of the optical nerve that enters the orbital globe was monitorized in the 2D mode without exerting much pressure. Diameter of the optic nerve sheath was measured 3 mm behind the optic disk using an electronic caliper after the right contrast was found between the retrobulber echogenic fatty tissue and the vertical hypoechogenic band	operation time 3 hours
