[Application of a device for evacuation of fragments of biological tissue and uroliths in endoscopic operations].

The proposed evacuator allows prevention of regurgitation of fragments of resected tissue of destructed bladder stones from the lower cavity of the device to the upper one, and then to the urinary bladder and, thus, it reduces loss of the biological material fragment for morphological investigation as well as the bladder stones fragments for an analysis of their chemical composition and structure, more effectively and quicklywash off the urinary bladder during endoscopic operations.
