Computed tomography window affects kidney stones measurements

Int. braz. j. urol; 45 (5), 2019
ABSTRACT Objectives Measurements of stone features may vary according to the non-contrast computed tomography (NCCT) technique. Using magnified bone window is the most accurate method to measure urinary stones. Possible differences between stone measurements in different NCCT windows have not been eval...

Preoperative proteinuria is associated with increased rates of acute kidney injury after partial nephrectomy

Int. braz. j. urol; 45 (5), 2019
ABSTRACT Purpose We investigated the association between preoperative proteinuria and early postoperative renal function after robotic partial nephrectomy (RPN). Patients and Methods We retrospectively reviewed 1121 consecutive RPN cases at a single academic center from 2006 to 2016. Patients without...

Psychological preparation reduces preoperative anxiety in children. Randomized and double-blind trial

J. pediatr. (Rio J.); 95 (5), 2019
Abstract Objective: To verify the effect of psychological preparation on the relief of preoperative anxiety in children and to correlate parents' and children's levels of anxiety.

Preoperative anxiety induces chronic postoperative pain by activating astrocytes in the anterior cingulate cortex region

SUMMARY OBJECTIVE The study aims to explore the relationship between preoperative anxiety and chronic postoperative pain. METHODS A total of forty rats were divided into four groups, control, single-prolonged stress alone, Hysterectomy alone, and SPS+ Hysterectomy. The paw withdrawal mechanical thres...

Pulmonary hypertension could be a risk for deep vein thrombosis in lower extremities after joint replacement surgery

SUMMARY A background of Pulmonary Hypertension (PH) indicates a progressive elevation of pulmonary vascular resistance, leading to overfilling, elevation of venous pressure, congestion in various organs, and edema in the venous system. This study aimed to investigate whether PH is a risk factor for deep ...

Impact of arterial procedures on coagulation and fibrinolysis - a pilot study

Abstract Objective: The main goal of our study was to assess the impact of vascular procedures on the activity of hemostatic and fibrinolytic pathways. Methods: We enrolled 38 patients with ≥ 45 years old undergoing surgery for abdominal aortic aneurysm or peripheral artery disease under general ...

Relationship of inter-arm systolic blood pressure difference with subclavian artery stenosis and vertebral artery stenosis in patients undergoing carotid endarterectomy

Abstract Introduction: The aim of this study was to examine the association of inter-arm systolic blood pressure difference (IASBPD) with carotid artery stenosis, subclavian artery stenosis and vertebral artery stenosis in patients who underwent carotid endarterectomy. Methods: A total of 141 patients ...

The expression of and preoperative correlation between heat-shock protein 70, euroscore, and lactate in patients undergoing cabg with cardiopulmonary bypass

Abstract Objetive: Coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) improved symptoms and increased survival and quality of life in patients with coronary artery disease. However, it should be the main cause of a complex organic systemic inflammatory response that greatly contrib...

Effect of preoperative creatinine levels on mortality after coronary artery bypass grafting surgery: an observational study

Abstract Introduction: Renal function is an independent risk factor for mortality among on-pump coronary bypass grafting (ONCABG) patients. This association is well known in the international literature, but there is a lack of knowledge of how admission creatinine (AC) levels modulate each cardiovascula...

Expanding the limits of endoscopic intraorbital tumor resection using 3-dimensional reconstruction

Abstract Introduction: Endoscopic orbital surgery is a nascent field and new tools are required to assist with surgical planning and to ascertain the limits of the tumor resectability. Objective: We purpose to utilize three-dimensional radiographic reconstruction to define the theoretical lateral limit...
