Lung Ultrasound Versus Inferior Vena Cava Collapsibility Index for Early Prediction of Volume Overload During Transurethral Resection of Prostate

Serial lung ultrasound will be performed to patients enrolled in this study before the beginning of the surgery, every 15 minutes in the first 30 minutes, and then every 30 minutes for the rest of the operation.lung ultrasound will be used as a tool for monitoring of EVLW to identify early the subclinical pulmonary edema and ensure timely and correct diagnosis and appropriate management.

Serial assessment of IVC collapsibility will be used as a monitoring of volume overload in patients enrolled in this study. Basal IVC scanning using ultrasound will be performed before the start of the operation and serial IVC scanning will be done during the procedure every 15 minutes in the first 30 minutes, and then every 30 minutes for the rest of the operation.
