Here’s a medical conundrum for all of you faithful viewers of “House” out there.
I’m throwing this out there because I have never seen it before. I did some internet searching and think that I came up with the answer (.pdf file) but I’m not positive.
The basic history is that the patient is a bed-bound nursing home resident who has had a conic Foley catheter. The nursing home stated that the urine had started to turn purple over the past 2 weeks. The degree of purple discoloration got more and less, but never went away. It had become particularly bad recently, prompting the call to the ambulance. Notice how even the tubing is purple-colored.
Labs and a UA were sent from the nursing home a week prior and showed some minor renal insufficiency, but were otherwise pretty normal (except for urine color).
Labs done in the ED showed continued renal insufficiency, a mildly elevated WBC count and a UTI. Remember – the patient had no UTI on a UA performed one week prior while she was still having symptoms.
So what is causing the Case of the Purple Urine?
