meningitis Does anyone know the relevance of the stem saying: "during this time she also has been crying frequently"? +49

usmleuser007 Think the postrenal azotemia is d/t her pregnancy. With the increasing in size fetus, the pelvic cavity is being compressed and thus there is pressure on the ureters. This leading to the presentation. As per above --- the crying maybe just d/t her pain and emotional stress caused by worrying about possible complications regarding her fetus. +4

maxillarythirdmolar My gut tells me it must be some sort of transient change in placental size with hormonal changes. It's reminiscent of what you might expect for breast changes during the menstrual cycle, imo +

j44n or maybe the fetus is literally crushing her ureters into the wall of her pelvis and shes got an infected kidney +3

I feel like part of this is them seeing if you can recognize those are tubules.

So if you say ok these are tubules, chorioamnionitis, endometritis, and PID are probably not right.
Glomerulonephritis in my experience so far, they should probably show a glomeruli, not tubules.

Between hematgoneous spread and obstructive uropathy, I feel like I don't have enough info - but sometimes a 50/50 guess is better than playing Battleship.

This question was a little tricky, but the way I went about it was process of elimination. You don't see costophrenic angle tenderness in A,B, C, or D.

She has fever and back pain, definitely don't see that in PID, which presents with cervical motion tenderness, and purulent discharge. Micrograph also isn't showing cervical histology.

As an added bonus: urinary stones cause excruciating pain when you're trying to pass it through your ureters, basically dragging alongside. Hence the patient crying.

You didn't need the micrograph, other than to see all those neutrophils, but we've all seen glomerulonephritis histology slides, and it doesn't even look close.

diegolc26 I thought it could be D or E at first. But the picture is really clear. There is inflammation within the tubules, not in the interstitium, that points more for Obstructive Uropathy which is also painful, can cause fever, and a risk factor could be compression due to elarged uterus. +
