Intra-operative feedback and dynamic compensation for image-guided robotic focal ultrasound surgery.

This paper describes a non-invasive remote temperature measurement technique integrated with a biomechatronic surgery system devised in our laboratory and named FUSBOT (Focal Ultrasound Surgery RoBOT). FUSBOTs use High-Intensity Focused Ultrasound (HIFU) for ablation of cancers/tumors and targets accessible through various soft-tissue acoustic windows in the human body. The focused ultrasound beam parameters are chosen so that biologically significant temperature rises are achieved only within the focal volume.

European consensus conference on diagnosis and treatment of germ cell cancer: a report of the second meeting of the European Germ Cell Cancer Consensus group (EGCCCG): part I.

Objectives: The first consensus report presented by the European Germ Cell Cancer Consensus Group (EGCCCG) in the year 2004 has found widespread approval by many colleagues throughout the world. In November 2006, the group met a second time under the auspices of the Department of Urology of the Amsterdam Medical Center, Amsterdam, The Netherlands.

Methods: Medical oncologists, urological surgeons, radiation oncologists as well as pathologists from several European countries reviewed and discussed the data that had emerged since the 2002 conference, and incorporated the new data into updated and revised guidelines.

Diagnosis and metaphylaxis of stone disease. Consensus concept of the National Working Committee on Stone Disease for the upcoming German Urolithiasis Guideline.

This review draws the recent state of the art in metabolic diagnosis and metaphylaxis of stone disease. It is the basis for the consensus approval with the other medical societies and institutions in Germany involved in the guideline process of the new "Urolithiasis Guideline". The German Working Committee on Stone Disease reviewed critically the current literature in the field of urolithiasis-including the existing German and EAU-Guidelines as well as the Conference Book of the First International Consultation on Stone Disease.

Germ cell tumour is the most frequent malignant tumour type in young men with a 100% rise in the incidence every 20 years. Despite this, the high sensitivity of germ cell tumours to platinum-based chemotherapy, together with radiation and surgical measures, leads to the high cure rate of > or = 99% in early stages and 90%, 75-80% and 50% in advanced disease with 'good', 'intermediate' and 'poor' prognostic criteria (IGCCCG classification), respectively. The high cure rate in patients with limited metastatic disease allows the reduction of overall treatment load, and therefore less acute and long-term toxicity, e.

Extracorporeal organotripsy for renal tumours.

Purpose Of The Review: The conviction that a renal cell carcinoma does not require the entire organ to be removed allows new therapeutic methods to be envisaged that involve only local tissue ablation, rather than the complete removal of the organ. The trend toward minimally invasive options in the management of renal tumours has prompted interest in energy-based ablation techniques as a possible alternative to radical or partial nephrectomy in selected patients. Cryoablation, radiofrequency interstitial tumour ablation, microwave thermotherapy and high-intensity focused ultrasound (HIFU) are among such techniques.

Clinical evaluation of a newly developed endoscopic resection device (Rotoresect): physical principle and first clinical results.

Background: Endoscopic resection techniques on benign prostatic tissue aim at a high ablation rate and a minimal bleeding rate. Although commercial resection electrodes are effective, they either cause high blood loss (loop electrode) or reduce the bleeding rate with a compromised ablation rate (electrovaporization electrode). To resolve these problems, a new electrosurgical resection device, The Rotoresect, has been developed.

What are the parameters for predictive selection of patients requiring anesthesia for extracorporeal shockwave lithotripsy?

Objective: Additional anesthesia is required to minimize the tolerable pain level in efficiently performed extracorporeal shockwave lithotripsy (ESWL) with electrohydraulic and electromagnetic sources. In order to assess optimum anesthesia for each patient undergoing a standardized ESWL protocol, pain measurement and scoring were carried out. We attempted to determine the individual type and amount of analgesia prior to treatment.
