[Experimental application of the jet scalpel in renal surgery in the dog].

With the aid of an original jet cutting apparatus 29 partial and 3 hemiresections of the kidney were performed in dogs. Another 10 animals, as a control group, were subjected to ordinary scalpel resection and electric knife treatment. Consideration has been given to immediate and early postoperative blood losses as well as to immediate and later-stage histomorphological changes in the resected organs. Due to the fine presentation of blood vessels and the kidney's pyelocaliceal system by the cutting jet, intraoperative blood loss was reduced. Other advantages of the system include reducing overall duration of the surgical intervention, no need for special training of the operator to use the apparatus, low cost of the apparatus and environmental cleanliness in the operation room compared with the use of conventional devices used for parenchymal resection.
