I chose the smaller format of patches, which proved strong enough for my daily occupations. I thought the less skin is covered, the better, being a bit afraid of a rash or irritation of the skin underneath the patch. But I had neither. And the result was absolutely surprising, it went beyond my expectations :

• no more sedation necessary
• no more stitching,
• no more feeling sore or less mobile after the catheter switch ,
• no more kinking of the catheter (between kidney and insertion point, which to me is the best proof that the patches should get priority to stitching),
• I have to spend less time in hospital since the appointment for the replacement now only takes about half an hour at the most instead of half a day in a hospital bed (which is not only time saving but also important from a financial point of view).
