Filter by:This study aim to analyze cost-effectiveness of robot-assisted surgery compared to open surgery for partial nephrectomy in the context of renal tumor. A total of 400 patients were recruited in two centers in France corresponding to Reims(n=200) and Nancy hospital center (n=200). Patients recruited in Reims are corresponding to open surgery strategy, while patients of Nancy center are corresponding to robot-assisted surgery. Costs analyzed included cost of intervention, hospital stay and complications. Effectiveness measure is corresponding to the rate of patients without acute complication at one year.
This study evaluates novel surgical approach in treating small renal masses. Half of participants will undergo hypotonic zero-ischaemia partial nephrectomy (standard of care), while the other half will undergo normotonic zero-ischaemia partial nephrectomy (experimental method).
Microwave thermal ablation (MO) is recognized as an alternative to surgery for the local-regional treatment of primary and secondary hepatic and renal tumors and for secondary pulmonary tumors in patients at anesthetic and/or surgical risk. Microwaves have a reputation for not producing reproducible ablation volumes with elliptical deformations and risks of over or under processing. The Covidien manufacturer offers a microwave system that guarantees more spherical and reproducible ablations: Emprint TM ablation system with Thermosphere TM technology (thermal control, field control, wavelength control). The investigators have 2 years of experience and therefore propose to carry out a first retrospective study, on a cohort of about fifty patients, whose objective will be to compare the volume of in vivo ablation one month after thermo-ablative treatment by microwave of a hepatic, renal or pulmonary tumour with the reference volume announced by the Covidien abacus manufacturer. Microwave ablation, which is much less studied, is less used because of the low reproducibility of necrosis volumes. The Covidien manufacturer offers a system that allows ablation volumes that are supposed to be reproducible, which attracted the Nîmes University Hospital during the call for tenders. To the investigator's knowledge, there are no studies that have evaluated the actual volume of ablation by this system.
In this trial the investigators want to examine and compare oncological and surgical outcomes of two surgical techniques in a prospective, randomised, single-blind trial. Therefore the investigators are going to include 30 patients with a renal mass who need surgical treatment. When they fulfill the inclusion criteria they get randomised either for robot-assisted partial nephrectomy or laparoscopic partial nephrectomy. Primary endpoint is the oncological outcome (residual tumor classification, TNM classification), secondary endpoints are operation time, time of ischemia, blood loss, pain after surgery, kidney function, complications and hospital stay.
The purpose of this study is to measure the volume of the kidney and tumors using 3D-US acquisition and to correlate these measurements to contrast-enhanced CT or MRI.
The aims of this work were to assess the feasibility, efficacy, short-term outcome and safety of microwave ablation in the treatment of malignant bone, lung and renal tumors.
The purpose of this study is to investigate the safety and efficacy of irreversible electroporation (IRE) for unresectable renal tumors.
The multimodal analgesia for postoperative pain aims for optimal analgesia through additive or synergic drug effects. The multimodal analgesia results in the use of smaller doses of opioids and lowering opioid-related side effects. Non-opioid analgesics, non-steroidal anti-inflammatory drugs (NSAIDs), propacetamol (prodrug of acetaminophen), nefopam are often given along with opioids as part of multimodal analgesia after major surgery. NSAIDS, commonly used non-opioid analgesics, have gastro-intestinal, renal, and cardiac side effects. In contrast, propacetamol or nefopam, two drugs with central analgesic effects, can be safely used as analgesic adjuvants with opioid after nephrectomy, because these drugs do not alter renal function or cause hemorrhagic complications. Recent study demonstrated that the antinociceptive properties of paracetamol (intravenous acetaminophen) associated with the analgesic effectiveness of nefopam could explain the observed synergy of the combination. The aim of this randomized, double-blinded study is to compare the opioid-sparing effect and analgesic efficacy, as well as quality of recovery, of nefopam-propacetamol combination and propacetamol in patients undergoing laparoscopic nephrectomy.
