Normally it is treated by inseration of a nephrostomy or pigtail catheter as well as surgical correction, which can involve several complications. The Memokath 051 is a thermo-expandable titanium-nickel spiral which can be used for treatment of long-term ureteric strictures. METHODS A total of 129 patients with ureteric strictures (main age 67 ± 11 years) were treated by insertation of a thermos-expandable titanium-nickel spiral (Memokath 051, PNN Medical). Complications and duration of spiral implantation were assessed under consideration of the patients age, ASA score as well as side, length and causation of the stricture. Moreover, the reasons for spiral explantation were evaluated. RESULTS Predominant reason for insertation of the analysed thermos-expandable spiral system were malignant obstructions of the ureter (n=60; 52%), followed by iatrogenic induced strictures after surgery (n=14; 13%) and postradiogenic fibrosis (n=17; 15%). Moreover, the mentioned system was implanted after radical cystectomy and ileum conduit installation (n=6; 5%). The median time until explantation of the Memokath system was 255 days (range: 22-2061), mainly caused by dislocation and occlusion. CONCLUSIONS The mentioned thermos-expandable spiral system Memokath 051 is a save and easily applicable tool for treatment of long-term ureteric strictures in patients without the possibility for surgical correction due to severe comorbidities. In contrast to the treatment with nephrostomy or pigtail catheter, which have to be changed regulary, patients with the Memokath system benefit from the extended duration of implantation. © 2016FiguresReferencesRelatedDetails Volume 195Issue 4SApril 2016Page: e474 Advertisement Copyright & Permissions© 2016MetricsAuthor Information Simone Bier More articles by this author Steffen Rausch More articles by this author Stefan Aufderklamm More articles by this author Tilman Todenhöfer More articles by this author Bastian Amend More articles by this author Eva Neumann More articles by this author Jens Bedke More articles by this author Christian Schwentner More articles by this author Arnulf Stenzl More articles by this author Stephan Kruck More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
