Male Catheterization Question

Does the head of penis need to be cleaned of the betadine post surgery? My understanding is that this solution leaves a stain on your skin unless it is scrubbed off. However, I showed no evidence of staining on my penis after my surgery. I can only guess that it was scrubbed off after the catheter was removed. Sorry for the dumb question, but I was just curious and figured someone here would have an answer.

Some of these cleaning solutions are clear, although I just had a cysto and dilation, and I had the tint

Betaine is not the only antiseptic available,however, if used, you can expect some remaining color.

Sammy normally betadine should be removed from the skin as it can cause irritation and itching. As Jds4med mentioned if it was used there would be a yellowish colour as they don't usually clean it off following surgery. Its usually done post surgery when you are back in your bed.

As Lynn said their are colourless antiseptic solution and in some places they use Normal saline to clean. So I doubt that they used betadine as there would be evidence of it.
