Which Interventional Device - expert independent opinion of interventional devices

This is a very easy stent to insert, but as Tze says there is no means of easy retrieval if inserted to far. The following images show insertion of the resonance stent in a patient with RPF. We wanted a stent that would not need changing as frequently as a plastic stent. The first image shows a new resonance stent inserted next to a Boston percuflex stent that had been in for 4 months. You can see only slight discolouration and the stent was still patent. It will be interesting to see the new stent after a year. One image shows the structure of the stent nicely as it is opened up by the curve in the bladder.

The classic Alken set sports a metal non flexible first dilator and is rather difficult to use unless you very frequently do this procedure. Rigid first dilator is, in my hands, a way to loss-of-access and/or perforation, which is why have been using Cook dilators now. With a flexible, disposable first dilator, followed by rigid metal dilators, I will have to reconsider my choice of instruments. Thanks for this review Thomas Muller, urologist, the Netherlands.
