Lung Ultrasonography score (LUS) using B-lines is a noninvasive, reliable and promising method for determining the extravascular lung water (EVLW). This was previously evaluated by trans-pulmonary thermodilution technique.
The transurethral resection of the prostate syndrome (TURP-S) is a potentially life-threatening complication of the TURP surgery and timely diagnosis of TURP-S is crucial for rapid detection and optimized treatment.
This observational study is designed to investigate the use of LUS using B-lines as a bed-side, simple, and non-invasive indicator for predication of the presence of systemic volume overload in patients undergoing endoscopic TURP.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Male patients with age ≥ 60 years undergoing TURP surgery | All patients will receive spinal anesthesia Under complete aseptic technique at level of L 4-L5 or L3-L4 using 12.5-15 mg of 0.5 % hyperbaric bupivacaine and 25 ug fentanyl. Lung ultrasound score: A curvilinear (5-2 MHz) probe will be used. The sliding multiple B-lines will be evaluated in eight antero-lateral lung examination zones. Inferior vena cava (IVC) measurement using ultrasound: A curvilinear (5-2 MHz) probe with B-mode scan will be used. Caval-Aorta index will be calculated by taking the ratio of the two respective diameters measured. Other vital parameter as ,heart rate (HR), Mean arterial pressure (MAP), oxygen saturation (SpO2), arterial blood gases (ABG), serum Na and K levels will be measured and recorded at same time as the following: (T0) ,(T1) ,(T2),(T3) ,(T30, T60, T90) intraoperative ,(T PACU),(T critical) |
