Thermal Ablation Articles

ORLANDO, FL USA (UroToday.com) - Management of renal masses involves extirpative treatment, ablation, and active surveillance. Nishant Patel and colleagues examined national trends in the management of renal masses, specifically those with benign histology.

As the clinical use of cryoablation for the treatment of cancer has increased, so too has the need for knowledge on the dynamic environment within the frozen mass created by a cryoprobe. While a number of factors exist, an understanding of the iceball size, critical isotherm distribution/penetration, and the resultant lethal zone created by a cryoprobe are critical for clinical application.

The purpose of this study is to investigate the feasibility and performance of a stationary, non-focused dual-sectored tubular transurethral ultrasound applicator for thermal exposure of tissue regions adjacent to the urethra for treatment of stress urinary incontinence (SUI) through acoustic and biothermal simulations on 3D anatomical models.

The purpose of the study is to determine if clear cell renal cell cancer (RCC) subtype predicts efficacy in percutaneous radiofrequency (RF) ablation of RCC.

Patients who underwent percutaneous RF ablation for histologically proven RCC subtypes were retrospectively reviewed.

Prostate cancer is the most common non-cutaneous cancer among men in the USA.[1] Focal laser thermal ablation (FLA) has the potential to control small tumours while preserving urinary and erectile function by leaving the neurovascular bundles and urethral sphincters intact.

Focal therapy (FT) is a treatment option for prostate cancer (PCa), which offers the possibility of an effective therapy in selected patients who have the localized disease, with a significant reduction in treatment related morbidity.

High intensity focused ultrasound (HIFU) is rapidly gaining clinical acceptance as a technique capable of providing non-invasive heating and ablation for a wide range of applications. Usually requiring only a single session, treatments are often conducted as day case procedures, with the patient either fully conscious, lightly sedated or under light general anesthesia.

To assess the feasibility, safety and clinical outcomes of image-guided percutaneous thermal ablation as salvage therapy for local recurrence of renal cell carcinoma (RCC) in patients initially treated surgically with curative intent.

MRI-guided transurethral ultrasound ablation (TULSA) uses directional thermal ultrasound under MRI thermometry feedback control for prostatic ablation. We report 12-month outcomes from a prospective multicenter trial (TACT).

Long-term data comparing partial nephrectomy (PN) and thermal ablation are lacking.

To update our experience with PN, percutaneous radiofrequency ablation (RFA), and percutaneous cryoablation for cT1 renal masses.

Locally advanced prostate cancer can cause bladder outlet obstruction, gross hematuria and frequent hospitalization. While these complications are commonly treated by palliative transurethral resection of the prostate, the improvement is often insufficient.

Stress Urinary Incontinence (SUI) is prevalent in adult women, attributed to weakened endopelvic supporting tissues, and typically treated using drugs and invasive surgical procedures. The objective of this in silico study is to explore transurethral high intensity ultrasound for delivery of precise thermal therapy to the endopelvic tissues adjacent to the mid-urethra, to induce thermal remodelling as a potential minimally invasive treatment alternative.

To evaluate survival of patients with localized T1a clear cell renal cell carcinoma (ccRCC) who received cryosurgery or thermal ablation compared to deferred therapy.

We included 733 patients with histopathologically confirmed localized T1a ccRCC who either received cryosurgery (n = 315) or thermal ablation (n = 155), as well as patients who deferred therapy (n = 263) from the 2000-2013 Surveillance, Epidemiology, and End Results Program urinary cancer file.

The aim of this retrospective study was to assess the safety and effectiveness of laser ablation (LA) in patients with small renal cell carcinomas (RCC) and increased risk of bleeding.

From 2013 to 2017, nine patients (six males, three females, aged 68.

To evaluate trends and factors predicting use of renal mass biopsy (RMB) for localized Renal Cell Carcinoma in the United States (US) in the context of current guidelines recommendations.

We queried the National Cancer Database for cT1-cT3N0M0 Renal Cell Carcinoma diagnosed between 2004 and 2015.
