Four techniques of intracorporeal lithotripsy are now available: ballistic, ultrasonic, electrohydraulic, and laser. Their therapeutic efficacies have generally been evaluated and compared, but very few data have been available on their relative risks of iatrogenic trauma to the urothelial wall. We conducted a comparative analysis of this risk by testing(More)
OBJECTIVE To evaluate the efficiency and tolerance of venovenous hemofiltration, hemodiafiltration, and hemodialysis with a two-pump system in a neonatal animal model of acute renal failure. DESIGN Prospective trial. SETTING Animal laboratory at a large university-affiliated medical center. SUBJECTS New Zealand white rabbits, weighing 3325 +/- 380 g.(More)
The main problem in thoracoscopic resection of lung nodules is the difficulty in localising the target. In the following we describe the use of an ultrasonographic, deflectable linear array probe of 7.5 MHz which was first tested during an in-vitro study. This study has provided useful information with respect to the US inspection of normal parenchyma and(More)
Most laparoscopic procedures require the creation of a pneumoperitoneum. In order to evaluate the potential hazards of bacteriemia related to insufflation, we conducted a study in the rat. Two groups of 20 Wistar rats were used for this study. Peritonitis was induced by opening the terminal ileum. Twenty-four hours later, 20 rats were insufflated at a mean(More)
BACKGROUND This study aimed to determine the prevalence of genetic and environmental vascular risk factors in non diabetic patients with premature peripheral arterial disease, either peripheral arterial occlusive disease or thromboangiitis obliterans, the two main entities of peripheral arterial disease, and to established whether some of them are(More)
In its anatomy and physiology the pig is comparable with humans and its organs can be considered for xenotransplantation. We have studied the lymphatic drainage of the heart and lungs in 15 pigs. A coloured mass was injected into the myocardium and/or beneath the visceral pleura. The first nodes coloured were directly injected again. No lymph node was(More)
To optimize artificial nutrition (AN) techniques for patients suffering from malnutrition or reduced intestinal absorption, utilization of energy fuels, especially glucose, requires better understanding. Because the liver plays a key role in glucose homeostasis, the aim of this study was to assess the effects of continuous intragastric and intravenous(More)
Laparoscopic urological surgery is currently in a phase of development. In order to evaluate the possibility of treating vesicoureteric reflux by laparoscopy, we performed an elongation of the submucosal ureteric tract via an extravesical approach (Lich-Gregoir) in 4 pigs. After creating a pneumoperitoneum, 4 trocars were introduced into the abdominal(More)
In order to test the feasibility of video-assisted pneumonectomy, we conducted an experimental study in an animal model. We performed 12 attempts of video-assisted pneumonectomy (7 on the right side and 5 on the left side) in pigs with an average weight of 43.5 kg. We used a combined technique of conventional and endoscopic dissection. A complication-free(More)
