Irreversible electroporation for prostate cancer: another promising focal therapy.

Radical treatment for prostate cancer is associated with significant morbidity. Percutaneous image-guided irreversible electroporation is a non-thermal ablative technique that has emerged as a valuable option. This study describes the case of a patient with prostate cancer who was successfully treated using irreversible electroporation.

Cost-effectiveness of radiofrequency ablation versus percutaneous ethanol injection for early hepatocellular carcinoma in a resource-poor setting: a randomized trial.

Objective: This study assessed the cost-effectiveness of radiofrequency ablation compared with percutaneous ethanol injection in patients with early hepatocellular carcinoma in relation to the objective response rate and costs related to the procedure.

Methods: This was a prospective single-center randomized trial. The primary outcome was cost-effectiveness.

Complication rates of transrectal and transperineal prostate fusion biopsies - is there a learning curve even in high volume interventional center?

Purpose: To analyze the learning curve regarding complication rates of transrectal prostate biopsy (TRPB) versus transperineal prostate biopsy (TPPB), using real time software-based magnetic resonance imaging ultrasound (MRI-US) fusion techniques, along with first year experience of transperineal approach.

Materials And Methods: retrospective unicentric cohort study at a quaternary care hospital. Medical records of all consecutive patients that underwent TPPB between March 2021 and February 2022, after the introduction of MRI-US fusion device, and those who underwent TRPB throughout the entire years of 2019 and 2020 were analyzed.

Transafferent nodal embolization for lymphocele treatment: case report.

Lymphoceles are collections of lymphatic fluid, mainly caused by major surgical approaches. Most lymphoceles are asymptomatic and limited, but some cases may require a medical management. Among the different techniques, transafferent nodal embolization has emerged as a minimally invasive option, with low morbidity and high resolubility, although it is not widespread in the Brazilian scenario.

Lung nodule localization in hybrid room before minimally invasive thoracic surgery: series of 20 cases and literature review.

Objective: To describe an experience in the preoperative localization of small pulmonary nodules and ground-glass lesions to guide minimally invasive thoracic surgery; in addition, a literature review was conducted, including the main advantages and disadvantages of the different agents used, and site marking in a hybrid operating room.

Methods: A retrospective search was conducted in a Interventional Radiology Department database, between March 2015 and May 2019, to identify patients undergoing preoperative percutaneous marking of lung injuries measuring up to 25mm.

Results: A total of 20 patients were included and submitted to descriptive analysis.

Can multiparametric magnetic resonance of the prostate avoid biopsies in patients with elevated PSA and surgical indication for benign prostatic enlargement?

Introduction: To evaluate the clinical dilemma of men with surgical indication due to benign prostatic enlargement (BPE) and concomitant elevated PSA, we analysed if multiparametric magnetic resonance imaging (mpMRI) could safely prescind the prostate biopsy.

Methods: Forty men with surgical indication due to BPE and concomitantly elevated PSA levels were prospectively enrolled and retrospectively analysed. All patients underwent 1.

Paradoxical Early Increase in Prostate-Specific Membrane Antigen Uptake Following Cryoablation for Local Recurrence After Radical Prostatectomy.

We report a case of a 43-year-old man who underwent a radical prostatectomy 3 years before the procedure (June 2015) for a locally advanced Gleason 7(4 + 3) prostate adenocarcinoma (pT3aN0), with negative surgical margins, followed by salvage radiotherapy. He also underwent antiandrogen therapy for biochemical relapse (bicalutamide) from October 2016 through May 2017, but prostate-specific antigen continued to rise (2.5 ng/mL [December 2017] and 3.

Comparison of complications rates between multiparametric magnetic resonance imaging-transrectal ultrasound (TRUS) fusion and systematic TRUS prostatic biopsies.

Purpose: The aim of this study was to compare the complication rates between transrectal ultrasound (TRUS) systematic prostate biopsy and multiparametric magnetic resonance imaging (MRI)-TRUS fusion prostate biopsy techniques.

Materials And Methods: This is a single-center retrospective study, institutional review board approved. Systematic TRUS and MRI-TRUS fusion prostate biopsy complication rates were compared in 967 men.

Injecting hemostatic matrix in the path of biopsies: efficacy, potential complications, and the management of such complications.

Objective: To describe the technique of injecting hemostatic matrix, as well as the experience of our interventional radiology department in its application.

Materials And Methods: We conducted a single-center study with retrospective analysis of the experience of our group in the use of hemostatic gelatin matrix in percutaneous biopsies.

Results: In a total of 73 biopsies in different organs, such as the liver, kidney, and spleen, hemostatic gelatin matrix was introduced into the coaxial needle.

Incremental diagnostic value of targeted biopsy using mpMRI-TRUS fusion versus 14-fragments prostatic biopsy: a prospective controlled study.

Objectives: To compare the incremental diagnostic value of targeted biopsy using real-time multiparametric magnetic resonance imaging and transrectal ultrasound (mpMRI-TRUS) fusion to conventional 14-cores biopsy.

Patients And Methods: Uni-institutional, institutional review board (IRB) approved prospective blinded study comparing TRUS-guided random and targeted biopsy using mpMRI-TRUS fusion, in 100 consecutive men. We included men with clinical-laboratorial suspicious for prostate cancer and Likert score ≥ 3 mp-MRI.

Magnetic resonance/transrectal ultrasound fusion biopsy of the prostate compared to systematic 12-core biopsy for the diagnosis and characterization of prostate cancer: multi-institutional retrospective analysis of 389 patients.

Objective: To determine the incremental diagnostic value of targeted biopsies added to an extended sextant biopsy scheme on a per-patient, risk-stratified basis in 2 academic centers using different multiparametric magnetic resonance imaging (MRI) protocols, a large group of radiologists, multiple biopsy systems, and different biopsy operators.

Materials And Methods: All patients with suspected prostate cancer (PCa) who underwent multiparametric MRI of the prostate in 2 academic centers between February 2013 and January 2015 followed by systematic and targeted MRI-transrectal ultrasound fusion biopsy were reviewed. Risk-stratified detection rate using systematic biopsies was compared with targeted biopsies on a per-patient basis.
