“…Roughly, energy sources can be divided in thermal and non-thermal. Thermal ablation includes the use of heating techniques, such as electrical current in radiofrequency ablation and convergence of acoustic waves in high intensity focused ultrasound (HIFU), and of freezing techniques, like using argon probes to induce repeated freeze-thaw cycles in cryotherapy [58]. An example of non-thermal ablation is irreversible electroporation, whereby pulses of electric current create permanent cell membrane pores that lead to cell death [59].…”

This article aims to summarise recent developments in surgical and minimally invasive therapies in the management of small renal masses (SRM). Recent FindingsThe incidence of the small renal mass is increasing. Standard management of the SRM is partial nephrectomy. More recently, use of ablative techniques to manage the SRM has been increasing and an exciting array of technical advances are currently being made in the field.Nephron-sparing surgery looks set to become more financially viable with the advent of newer robotic platforms and, potentially even less invasive with the evaluation of single-port access. Real-time imaging promises to improve tumour definition, nephron preservation and vascular management intraoperatively. SummaryAdvances in surgical and minimally invasive therapies for the management of the SRM have the potential to improve cancer clearance and long-term renal function preservation. Patients will experience safer, more reliable and less invasive treatments for their small renal tumours. We describe the current advances underlying these changes.

“…The healthy tissue around the antenna tip and tumor are still around 50°C. Although healthy cells do not die even if kept at this temperature for a few minutes [1], it is thought that a slight increase in body temperature occurs as one side effect of biological reactions. …”

A new interstitial antenna for microwave ablation

Abstract:We propose an interstitial coaxial antenna that can insert without a catheter for microwave ablation therapy, operating at 2.45 GHz. The cap of the antenna is an arrowhead that bonds copper plate and ceramic plate to suppress heat conduction in the tip direction. The temperature distribution in the improved liver phantom is measured by using the infrared thermography device. As a result, it is clarified that we nearly get the spherical distribution of an assumed tumor in shape.

“…Microwave ablation (MWA) is a minimally invasive technique increasingly used for thermal therapy of tumors [1]. It requires efficient interstitial antennas that destroy spherical tumor of early stage and maintain a margin of healthy tissues while minimizing damage to the rest of the organ.…”

A new interstitial choke embedded antenna for microwave ablation

Abstract:We propose an interstitial coaxial antenna with a choke embedded in the outer conductor and with an arrowhead cap for microwave ablation therapy, operating at 2.45 GHz. The cap consists of ceramic and conductor. The heating is suppressed along both the direction in the tip side and the feeding side of the antenna because of the cap and the choke. In addition, a catheter is not required. We numerically clarify these advantages by analyzing the temperature distribution of a spherical breast tumor.
