Performance of the phonatory deviation diagram in the evaluation of rough and breathy synthesized voices

Abstract Introduction Voice disorders alter the sound signal in several ways, combining several types of vocal emission disturbances and noise. The phonatory deviation diagram is a two-dimensional chart that allows the evaluation of the vocal signal based on the combination of periodicity (jitter, shimm...

Comparison of inflammatory markers between brucella and non-brucella epididymo-orchitis

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Objectives: Brucellosis is a multi-system infectious disease that is associated with inflammation, which causes an increase in acute phase reactants. Hematological inflammatory markers of brucellosis include mean platelet volume (MPV), red cell distribution width (RDW), neutrophil/lymphocyte ra...

The preoperative stratification of patients based on renal scan data is unable to predict the functional outcome after partial nephrectomy

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Introduction: eGFR-categories are used to predict functional outcome after partial nephrectomy (PN); no study categorized patients according to preoperative renal scan (RS) data. Aim of the study was to evaluate if stratification of patients according to RS is a reliable method to predict minor...

Impact of PSA density of transition zone as a potential parameter in reducing the number of unnecessary prostate biopsies in patients with PSA levels between 2. 6 and 10. 0 ng/mL

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Purpose: To assess the accuracy of prostate-specific antigen (PSA) adjusted for the transition zone volume (PSATZ) in predicting prostate cancer by comparing the ability of several PSA parameters in predicting prostate cancer in men with intermediate PSA levels of 2.6 - 10.0 ng/mL and its abili...

Effect of phyllanthus niruri on metabolic parameters of patients with kidney stone: a perspective for disease prevention

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Phyllanthus niruri (P.niruri) or stone breaker is a plant commonly used to reduce stone risk, however, clinical studies on this issue are lacking. Objective: To prospectively evaluate the effect of P. niruri on the urinary metabolic parameters of patients with urinary lithiasis. Materials and ...

The role of bladder diverticula in the prevalence of acute urinary retention in patients with BPH who are candidates to surgery

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Introduction: The urinary bladder diverticula (BD) secondary to benign prostatic hyperplasia (BPH) is a complication that can lead to urinary stasis, stone, urinary tract infection (UTI) and tumors. It's role in acute urinary retention (AUR) is not totally understood. Objectives: To determine ...

The diagnostic value of FNDC5/irisin in renal cell cancer

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Purposes: The aim of this study was to determine the diagnostic significance of fibronectin type III domain containing protein 5 (FNDC5)/Irisin levels in the sera of patients with renal cell cancer. Materials and Methods: In the study, 48 individuals were evaluated. The patient group included ...

Predictive value of mean platelet volume in saphenous vein graft disease

Abstract Objective: To determine whether mean platelet volume (MPV), platelet distribution width (PDW), and platelet count could be used as determinants of mortality following coronary artery bypass graft (CABG) surgery and patency of saphenous vein grafts (SVG). Methods: The records of 128 patients wh...

Thrombocytopenia after transcatheter valve-in-valve implantation: prognostic marker or mere finding?

Abstract Objective: To analyze the behavior of platelets after transcatheter valve-in-valve implantation for the treatment of degenerated bioprosthesis and how they correlate with adverse events upon follow-up. Methods: Retrospective analysis of 28 patients who received a valve-in-valve implant, 5 in a...

Predictors of postoperative acute kidney injury after coronary artery bypass graft surgery

Abstract Objective: The aims of this study were to identify the risk factors associated with acute kidney injury (AKI) after isolated surgical revascularization with cardiopulmonary bypass and to develop a model to predict the appearance of postoperative AKI. Methods: A total of 435 adult patients who ...
