FIELD: medicine. SUBSTANCE: in the first version, the device includes a tube-casing with a union and a sealing elastic cuff located in the upper part of the tube-casing. The device contains an endoscope with a hollow instrumental channel, introduced through the sealing elastic cuff into the tube-casing with an annular gap between them. The device comprises a system for irrigation liquid supply to the kidney cavity. The device comprises a system for irrigation liquid outflow from the kidney cavity and a sealed stone collection vessel connected to an opening at the top of the tube-casing below the sealing cuff. The system for irrigation liquid supply to the kidney cavity, connected by a flexible hose with a union located on the side surface of the tube-casing below the sealing elastic cuff. The liquid supply system comprises a container with liquid and an air compressor with a control system and an air pressure sensor connected to the top of the container with liquid. Signal output of the pressure sensor is connected to the input of the compressor control system. The system for irrigation liquid outflow from the kidney cavity contains a liquid collection tank, a pump with a control system and a pressure sensor in the hose. The liquid collection tank is connected through the pump by a flexible hose with a hollow endoscope instrumental channel above the sealing cuff. The sensor output signal is connected to the input of the pump control system. In the second version, the system for irrigation liquid supply to the kidney cavity comprises a container with liquid, a pump with a control system connected between the liquid container and the flexible hose. The pump is connected to the union of the tube-casing located on the side surface of the tube-casing below the sealing elastic cuff and the pressure sensor in the hose whose signal output is connected to the input of the pump control system. In the third version, the system for irrigation liquid supply to the kidney cavity comprises a container with liquid located 20-80 cm above the operating field level and connected with a tube-casing union by a flexible hose. The union is located on the side surface of the tube-casing below the sealing elastic cuff. EFFECT: reduced risk of kidney tissues injury during the procedure for percutaneous removal of stone fragments, simplified and shortened procedure. 3 cl, 3 dwg

The results of the ultrastructural study of the epithelium of the patient cervix infected by the human papillomavirus (HPV) types 16 and 18 before and after treatment by contrasting thermo-laser therapy (CTLT) are presented. It was shown in this work that 1.5 and 6 months after treatment HPV DNA was not detected in the biopsy and the smear of the cervix using the polymerase chain reaction (PCR). In the ultrathin sections, the structure of the epithelial cells from the biopsy after treatment corresponded to norm. There was effective elimination of HPV types 16 and 18 as Induces by CTLT method.

The outfit Romashka-2 intended for evaporation, coagulation and preparation of thin biostructures in the superficial and deep operative fields by focused radiation of CO2 laser is widely used mostly in gynecology, otolaryngology and other branches of medicine. Experience gained with the 4-years' clinical trial of the outfit, carried out at one of the women's consultation clinics permitted one to assess the Soviet public health requirement of the outfits Romashka-2 as well as to calculate the economic effect provided by its use.

Employment of laser for restoration of adequate blood flow in atherosclerotic vessels is a radically new approach to treatment of cardiovascular diseases of atherosclerotic genesis. Since 1983, wide-scale experimental work has been done at A.N. Bakulev Institute of Cardiovascular Surgery, USSR Academy of Medical Sciences, which has formed the basis for transluminal laser angioplasty (vascular recanalisation with high-intensity laser beam), laser atherolysis (regression of atherosclerotic formations under low-intensity laser beam), and their combinations. Clinical application of these procedures was started in 1985. Sixty-two patients with ischaemic heart disease, Takayasu's and Leriche's syndromes, chronic occlusion of pelvic and lower-limb arteries, and with combined lesions of the arterial bed were exposed to targeted transluminal laser. Laser endovascular therapy alone and in combination with balloon angioplasty or bypass surgery was used. Application of these methods showed their high efficacy. Successful recanalisation and restoration of adequate flow (confirmed by Doppler echography and angiography) were achieved in 93 per cent cases; results were poor (no effect, complications) in 7 per cent cases.
