摘要：
The invention relates to the field of medical devices and can be used in urology for drainage of the upper urinary tract. Utility model increases to 40-75% duration of use of the stent patient and significantly improves the usability of the stent patient and physician through more rare replacement of one stent to another, and expands the arsenal of technical means that may be used as a ureteral stents in plan and especially in emergency situations. This is achieved in that, in a ureteral stent formed in a tube of polymeric bioinert memory material, with lateral perforations, a linear portion and a clamp at each end of the tube, the stent is made collapsible in which the distal clamp and connected thereto linear portion of the stent formed of a tube 1 with an external diameter of not more than 4.0 mm, wherein the linear portion includes the inner surface of the retainer is not connected to the end of the thread is not less than 15 mm in length, with the proximal retainer and linear portion of the connections of the stent with it a length not less than 220 mm made of two tubes with an external diameter of at least 2.0 mm, wherein the linear portion includes the outer surface is not connected to the mating thread end clamp of at least 15 mm in length, the length of each of the linear portions of the stent and the thread length on each of them are chosen so that when creating a threaded connection between the threads and corresponding thread length of at least 5 mm in length of the linear section of the assembled stent was 220-320 mm, and the perforations are made by Sun th the length of the tubes 1 and 2 except for the thread.Полезная модель относится к области изделий медицинского назначения и может быть использована в урологии для дренирования верхних мочевыводящих путей. Полезная модель увеличивает на 40-75% продолжительность использования установленного стента пациентом и существенно повышает удобство использования стента пациентом и врачом за счет более редкой зам
