 Hey guys, welcome to day 21 of our pants review series, our 30 day series where I select an O-Card at random that I personally use to study for the pants to hopefully help you guys study for the pants with this pants review series. Today's question is going to be all about kidney stones. They suck. They're painful. I've never had one, but people say they're the worst. Okay? So, all about kidney stones. I'm going to ask you a couple of quick questions about kidney stones. Question number one, what is the most common type of kidney stone? Question number two, what is the most common location to have a kidney stone? Question number three, what is the way to diagnose the kidney stone? What is the best way to diagnose a kidney stone? Oh, and then bonus question number four, sizes of kidney stones. What size of kidney stone usually is able to pass on its own, this size or smaller, and then what size usually needs a procedure for it to be taken out or possibly broken up using lithotripsy? All right, so I just gave you a lot of questions. I'm going to give you guys a few seconds to think about the most common type of kidney stone, the most common composition of kidney stone, the most common location, how it's diagnosed, and also sizes, what size of kidney stone will pass on its own usually, and what kind needs a lithotripsy or some sort of procedure to get it out of there. All right, give you guys a few seconds to think about it. Okay, anyway, so the most common type of kidney stone is calcium oxalate. The most common type of kidney stone is calcium oxalate. The most common location is the UVJ, the urethro, what is the, I'm going to Google that real quick, the urethro, oh my God, I can't even say it. I'm not a urologist. Okay, so the most common location to have a kidney stone is the UVJ, the urethro vesicular junction, and I'll post a picture of it right now, the urethro vesicular junction, where the ureter and the vesicle, in this case the bladder, kind of meet. So it's the junction of the ureter and the bladder, the urethro vesicular junction. That's a bad picture. I want to find another one. Let's see the urethro pelvic junction. There it is. Okay, urethro vesicular junction. Okay, so I'll post a picture of the UVJ, the urethro vesicular junction, and if you look at the anatomy, it kind of makes sense why it's more common to have it lodged there. So take a look at that, and then we're going to move on. So sorry about that. Hey, if I don't know something, I don't know something. I am not above Googling things. So most common type of stone is the calcium oxalate stone. The most common location is the UVJ, the urethro vesicular junction. The way you diagnose it was with a CAT scan, a CT scan. And then the size is, at least according to my note card, less than five millimeters, a stone less than five millimeters, half a centimeter, usually passes on its own quite painfully, but passes on its own. And then a stone larger than eight millimeters, eight millimeters, usually needs a lithotripsy or some sort of procedure to get it out of there. Alright, so last but not least, let's repeat that one more time because that was a lot of information for kidney stones. The most common type of kidney stone is the calcium oxalate stone. The most common location is the UVJ, urethro vesicular junction. You diagnose kidney stones with a CT scan and sizes under five millimeters generally passes on its own over eight millimeters generally needs a procedure to get it out.
