Hi, This is a followup to my other topic here. Tomorrow, I go in for a pharmacokinetic study. Now, in addition to giving blood samples drawn at 0.5 hours, 1 hours, 3 hours, 4 hours, 6 hours, 8 hours, and 24 hours; they’ll be collecting my urine. During my stay, the nurse will ask that I use a new collection cup whenever I need to go, then will add it to an ongoing collection. At the end of day 1, they will provide me with a collection container for that night and the next morning before I return for day 2. Now, I understand that these collections require every little drop of urine, because it’s important. That brings me to my question: How am I supposed to collect it during a bowel movement? Most of the time, my #1 and #2 come out at the same time. My hands are pretty big, so I don’t think I can fit the cup under my penis. Do I empty my bladder as best I can and then move my bowels, or do I sit up a little to the front so my penis isn’t inside the toilet seat and I can collect it that way? ---

You hold the cup underneath the tip of your penis. I’m not sure what part of this is supposed to be difficult. ---

The fact that I have big hands and can’t necessarily fit the cup in the toilet with my penis at the same time when I’m sitting down. ---

If I recall correctly, they will give you a “hat” that fits in the toilet in such a way that you can catch what you can need to catch and then empty it into a container. It can be positioned to catch what you want and let the rest go on by. Rinse it after you’ve finished, place it by the toilet, and you’re ready for the next round. ---

When my kidney problems first appeared the doctor told me to collect urine for 24 hours. I had bottles and jars all over the place until I realized he only wanted mine. ---

You had to defecate into a hat, but you’re still kind of hazy in your recollection of the event? How is that possible? ---

Well, came back from the study, and got the urinal to go with the bottle. As far as I know, sit down, penis in urinal, and just move up a bit. ---

Actually, I am quite clear on shitting in the hat and transferring the results into tubes. I gag just thinking about it. It was the urine collection I was less certain about. We used them in the hospital. I wasn’t sure if the OP would be sent home with one. ---

OP was actually quite lucky today. Large intestine’s going to be quite empty tonight as I ended up having two huge movements today. (One before I left, and one just after collecting the urine sample.) ---
