PURPOSE Irreversible electroporation (IRE) is a novel nonthermal tissue ablation technique by high current application leading to apoptosis without affecting extracellular matrix. Previous results of renal IRE shall be supplemented by functional MRI and differentiated histological analysis of renal parenchyma in a chronic treatment setting. METHODS Three(More)
INTRODUCTION Focal ablation therapy is playing an increasing role in oncology and may reduce the toxicity of current surgical treatments while achieving adequate oncological benefit. Irreversible electroporation (IRE) has been proposed to be tissue-selective with potential advantages compared with current thermal-ablation technologies or radiotherapy. The(More)
PURPOSE The nonthermal irreversible electroporation (NTIRE) is a novel potential ablation modality for renal masses. The aim of this study was the first evaluation of NTIRE's effects on the renal urine-collecting system using intravenous urography (IVU) and urinary cytology in addition to histology and magnetic resonance imaging (MRI). METHODS Eight(More)
PURPOSE The nonthermal irreversible electroporation (NTIRE) is a novel nonthermal tissue ablation technique by local application of high-voltage current within microseconds leading to a delayed apoptosis. The purpose of this experimental study was the first angiographic evaluation of the acute damage of renal vascular structure in NTIRE. METHODS Results(More)
AIM This study was designed to evaluate the performance of shear-wave elastography as a diagnostic tool for prostate cancer in a larger cohort of patients than previously reported. PATIENTS AND METHODS Seventy-three patients with suspected prostate carcinoma were investigated by ultrasound elastography followed by directed biopsy. The elastographic and(More)
It is postulated that focal IRE affords complete ablation of soft-tissue tumours while protecting the healthy peritumoral tissue. Therefore, IRE may be an interesting option for minimally invasive, kidney-tissue-sparing, non-thermal ablation of renal tumours. With this current pilot study (“IRENE trial”), we present the first detailed histopathological data(More)
BACKGROUND Local ablation techniques are a major focus of current developments in oncology. The primary aim is to retain organs and preserve organ functions without compromising the oncological outcome. METHOD Irreversible electroporation (IRE) is a novel ablation technique that involves the application of high-voltage pulses to induce cell apoptosis(More)
BACKGROUND In patients with low-risk prostate cancer (PCa) the standard therapies carry a risk of overtreatment with potentially preventable side effects whereas restrained therapeutic strategies pose a risk of underestimation of the individual cancer risk. Alternative treatment options include thermal ablation strategies such as high-intensity focused(More)
The American Association for the Surgery of Trauma (AAST) injury scoring scale is commonly used for genitourinary injuries. Normally, grade 4-5 lacerations of the kidney show involvement of the pelvicalyceal system (PCS) with urine extravasation (UE). We present a case of a 41-year-old woman who was hospitalised with macrohaematuria and retroperitoneal(More)
