This happened a few days ago and has sense then peaked my interest in sounding rods as i know know what there called. Please forgive my stating wands as that was not correct. I had an injury years ago, and it caused a urethral stricture, and it has slowly gotten tighter, and I was having problems urinating. So off to the urologist, after he scoped it and said that it would have to have the scar tissue pulled apart, I set up a date to have it done. So at my appointment, I am lying naked except for a thin sheet waiting on the doctor when the nurse came in, she said she would be doing the procedure and started preparing everything she would need. So here I am staring at these slender wands that slowly get bigger at the base thinking oh shit I want out of here. She chatted with me as she got everything in order, and I found out she is in her last year at UF and had worked with the doctor for several years. So the first thing she does is insert a syringe with a numbing agent into my penis, and she is looking around for something and says I forgot the clamp to keep the (whatever the name of the stuff was) from being pushed out.
She asked me if I want to have her get a clamp and start over or hold it closed. I say I can hold it as I was getting a bit embarrassed about it.
She could not allow me because my hands weren't sterile, and she did not mind keeping it closed for the time it took to work.
