摘要：
The utility model relates to medicine, namely, to the structures of stents that may be used in the treatment of various renal pathologies, in particular by intrauterine fetal kidney stenting in obstructive malformations of the genitourinary system. Improving the reliability of the stent fixation and, consequently, reduce the possibility of undesired spontaneous migration, reducing the material consumption of the stent by reducing curls size is achieved in that in the stent renal comprising a hollow tube of flexible material having a substantially rectilinear portion and associated with her perforated distal and curved proximal ends, each in the form of a spiral curl with one turn, capable of straightening and subsequent spontaneous return to original form, each perforated distal and proximal bent end in the form of a curl spiral lies in a plane inclined relative to a substantially rectilinear part of the hollow tube, wherein the essentially straight portion and a perforated distal and proximal curved ends are conjugate through a radial bent portion, a portion of which is made in coplanar with the curl so that the curl of each end helix is arranged concentrically with respect to a substantially straight portion of the stent. It is preferred that each perforated distal and a proximal end bent to form curl spiral located in a plane perpendicular relative to a substantially rectilinear portion of the stent.Полезная модель относится к медицине, а именно, к конструкциям стентов, которые могут использоваться при лечении различных почечных патологий, в частности, путем внутриутробного стентирования почек плода при обструктивных пороках развития мочеполовой системы. Повышение надежности фиксации стента и, соответственно, уменьшение возможности его нежелательной самопроизвольной миграции, уменьшение материалоемкости стента за счет уменьшения размера завитков достигается тем, что в стенте почечном, содержащем полую трубку из эластичного материала, имеющую в основном прямолин
