Košina J, Balík M, Holub L, Hušek P, Pacovský J, Broďák M. Extra-anatomic stents as an alternative of nephrostomy. Extra-anatomic stents represent an alternative to the nephrostomic tube for patients with ureteric obstruction in whom the ureteral stenting failed. They are designed for patients with extramural obstruction of ureters caused by abdominal or pelvic tumors or severe form of retroperitoneal fibrosis. The main advantage of extra-anatomic stents is that they do not require use of nephrostomic tube and urine bag. The introduction is not difficult and all currently available extra-anatomic stents have all the necessary components for implementation included in the package. Quality of life improvement and the amelioration of renal insufficiency are the main goals for insertion of the extra-anatomic kidney stent. The aim of this article was to review and assess the published literature.

Keywords: Extra-anatomic stent, nephrostomy, extramural obstruction of ureter.
