Prostate volume measurement by multiparametric magnetic resonance and transrectal ultrasound: comparison with surgical specimen weight

ABSTRACT Objective To assess accuracy of multiparametric magnetic resonance of the prostate to estimate gland volume, comparing the results with transrectal ultrasound and surgical specimen. Methods A retrospective study of 85 patients who underwent multiparametric magnetic resonance and transrectal ...

Acute postoperative sepsis mimicking symptomology suspicious for malignant hyperthermia: case report

Rev. bras. anestesiol; 69 (6), 2019
Abstract Background: Sepsis is a life-threatening organ dysfunction with non-specific clinical features that can mimic other clinical conditions with hyper metabolic state such as malignant hyperthermia. Perioperatively anesthesia providers come across such scenarios, which are extremely challenging wit...

Use of artisanal simulators in the ultrasound training for invasive procedures in nephrology: venous access and renal biopsy

J. bras. nefrol; 41 (3), 2019
ABSTRACT Introduction: Vascular access and renal biopsy are common procedures in nephrology. In this study, two artisanal simulators of very low cost and excelent image quality are (prented) presented to guide, by ultrasound, the venous access and renal biopsy. Methods: The simulators are constructed u...

Is possible to rule out clinically significant prostate cancer using PI-RADS v2 for the assessment of prostate MRI?

Int. braz. j. urol; 45 (4), 2019
ABSTRACT Objectives To evaluate the diagnostic performance and interobserver agreement of PI-RADS v2. Materials and Methods In this Institutional Review Board approved single-center retrospective study, 98 patients with clinically suspected PCa who underwent 3-T multiparametric MRI followed by MRI/TR...

Detection of clinically significant prostate cancer with PI-RADS v2 scores, PSA density, and ADC values in regions with and without mpMRI visible lesions

Int. braz. j. urol; 45 (4), 2019
ABSTRACT Purpose To determine if PSAD, PSADtz, and ADC values improve the accuracy of PI-RADS v2 and identify men whose concurrent systematic biopsy detects clinically significant cancer on areas without mpMRI visible lesions. Materials and methods Single reference-center, cross-sectional, retrospecti...

Impact of PI-RADS v2 on indication of prostate biopsy

Int. braz. j. urol; 45 (3), 2019
ABSTRACT Objectives: To identify the group of patients who could safely avoid prostate biopsy based on the findings of multiparametric prostate resonance imaging (MRmp), parameterized with PI-RADS v2, using prostate biopsy as reference test and to assess the sensitivity and specificity of mpMR in identi...
