“…There are few detailed reports on the patency of ureteric stents in extrinsic ureteric obstruction [ 3, 18]. Rackson et al [ 18] suggested that the best patency rates thus far were achieved with C‐flex stents with a large lumen.…”

“…There are few detailed reports on the patency of ureteric stents in extrinsic ureteric obstruction [ 3, 18]. Rackson et al [ 18] suggested that the best patency rates thus far were achieved with C‐flex stents with a large lumen. Lugmayr and Pauer [ 9] reported that when compared with the patency rates published for the various stents, the patency of metal stents was within the range of those of the C‐flex stents.…”

“…Befürworter des Silikons heben dessen Bioverträglichkeit, Inertheit und Weichheit hervor [9], während Polyurethan wegen der geringen Drainagequerschnitte bevorzugt wird [13]. Copolymere aus Polyurethan und Silikon, die auch schon bei den Entwicklungsversuchen von Kunstherzen eine Rolle spielten, sollten die positiven Eigenschaften beider Materialien vereinen [5,22]. Hydromerveredelte Oberflächen imitieren eine Wasser-und bindegewebeähnliche Matrix und sollten dadurch das oben genannte Eigenschaftsprofil erreichen [1] (Abb.…”

“…The theoretical benefits of a Wallstent device in the ureter are (1) its potential incorporation into the uretenc wall, which should prevent migration, incrustation, infection, on hematunia, as seen with double-pigtail catheters [1 7]; (2) a longer duration of patency compared with that of double-J catheters; and (3) physiologic urine flow to the bladder. [6,7,18].…”
