Kidding aside, is a four-hour erection in an adolescent to be expected and thus not cause for concern?

Any pediatric urologists in the house? Is pediatric urology even a specialty? 😕

Not, it is not expected and is still a cause for concern. The most common causes of priaprism in adolescents (and children) are sickle cell and perineal trauma.

Adolescents may get more \*frequent \*erections than adults (although I’m not entirely sure about that, that’s based on water cooler talk rather than research), but they still shouldn’t be unremitting.

Yup, and just like regular ones, you don’t want to have to meet them. My baby son had posterior urethral valves, we have his 6 month follow up visit with, no joke, Dr. Huang, next week.

With low flow priaprism, the least invasive interventions are ice to the groin and perineum, pressure on the perineum and having the man walk up some stairs.

If ice, pressure and stairs don’t do it, they’ll probably give you one or more drugs which may make the erection go away - terbutaline taken orally resolves about one third of the cases. Some docs will use oral pseudoephedrine, but I’m not sure how widely that’s accepted yet. If that doesn’t work within 30 minutes, an injection of an alpha-adrenergic blocker will be attempted. Third line of intervention is the aforementioned aspiration of the blood in the corpus carvernosum with a needle. If this doesn’t work they’ll also inject alpha-adrenegeric blockers or methyline blue into the cavernosum itself

I love it when you talk nerdy to us.

I’ll be in my bunk.

Ok, see you in 3 hours and 59 minutes, or we’re sending a urologist in there with a needle!  
(Sorry if my nerdiness is too much. I actually use this site (and a couple of others) to practice my 'splaining skills. Someday I may actually need to nerd out at a patient or his wife in real life, and having some things rehearsed in layspeak like “blood can’t get out” will, I hope, make me a better nurse!)

Sometimes, there’s a fistula (opening) where it shouldn’t be that’s causing the blood to keep coming into the penis, and a simple procedure is needed to close the fistula, either with angiography or surgical incision.

This may also be treated with drugs that cause the blood vessels of the penis to constrict, thereby reducing the amount of blood that can flow into the penis. Said drugs may be administered intravenously or by injection directly into the penis.

If the urologist suspects that ischemic (low flow) priapism is caused by a blood clot, anti-clotting drugs may be used.

Do they use thrombolytics to actually break up the clot, or things like heparin to prevent more? Or both? Do you have any more information on clots and priapism? We didn’t cover that cause in class, except tangentially r/t sickle cell.

Obligatory TSA witty comment here.

The last “Untold Stories of the ER” had just such a patient, as well as the dudes wife rushing to the ER only to discover her hubby holding hands with his mistress waiting the Urologist exam.  
They took him to surgery and attacked his warrior with a needle.

I’m 30 going on 12. This made my morning, after I sat for a moment sounding it out. (Hope your son’s okay, of course. But still, thanks for the lol.)

Looks like both approaches have been tried - I found references to the use of streptokinase, heparin, and warfarin.

This seems to associated with sickle-cell disorder more than anything else. Sickling can make the blood more liable to clot anywhere in the body. The penis, or the blood vessels associated with it, are no exception.

I believe our \*\*Qadgop \*\*has treated a couple of men with priapism related to sickle cell disease.

You could watch that episode of True Blood where the brother drinks all the vamp blood… It describes the needle thing pretty squickishly.
